Description

Angular-Slickgrid ships with a few default inline editors (checkbox, dateEditor, float, integer, text, longText, slider). You can see the full list here.

Note: For the Float Editor, you can provide decimal places with your column definition, defaults to 0 decimal places (e.g. editor: { params: { decimalPlaces: 2 }})

Required Grid Option

Editors won't work without these 2 flags enableCellNavigation: true and editable: true enabled in your Grid Options, so make sure to always to always defined them. Also note that you can toggle the grid to read only (not editable) via the editable grid option flag.

How to use Inline Editors

Simply call the editor in your column definition with the Editors you want, as for example (editor: { model: Editors.text }). Here is an example with a full column definition:

this.columnDefinitions = [
  { id: 'title', name: 'Title', field: 'title', type: FieldType.string, editor: { model: Editors.longText } },
  { id: 'duration', name: 'Duration (days)', field: 'duration', type: FieldType.number, editor: { model: Editors.text } },
  { id: 'complete', name: '% Complete', field: 'percentComplete', type: FieldType.number, editor: { model: Editors.integer } },
  { id: 'start', name: 'Start', field: 'start', type: FieldType.date, editor: { model: Editors.date } },
  { 
    id: 'finish', name: 'Finish', field: 'finish', type: FieldType.date, 
    editor: { 
      model: Editors.date,
      
      // you can also add an optional placeholder
      placeholder: 'choose a date'
    }
  },
  { 
    id: 'effort-driven', name: 'Effort Driven', field: 'effortDriven', formatter: Formatters.checkmark, 
    type: FieldType.number, editor: { model: Editors.checkbox } 
  }
];

this.gridOptions {
  enableCellNavigation: true, // <<-- VERY IMPORTANT, it won't work without this flag enabled
  editable: true,
};

Demo with Float Editor and Dollar Currency Formatter

This probably comes often, so here's all the setting you would need for displaying & editing a dollar currency value with 2 decimal places.

this.columnDefinitions = [
  { 
    id: 'cost', name: 'Cost', field: 'cost', 
    type: FieldType.float, 
    formatter: Formatters.dollar, // the Dollar Formatter will default to 2 decimals unless you provide a minDecimal/maxDecimal
    // params: { minDecimal: 2, maxDecimal: 4, }, // optionally provide different decimal places

    // the float editor has its own settings, `decimal` that will be used only in the editor 
    // note: that it has nothing to do with the Dollar Formatter
    editor: { model: Editors.float, decimal: 2 },
  },
];

Editor Output Type & Save Output Type

You could also define an outputType and a saveOutputType to an inline editor. There is only 1 built-in Editor with this functionality for now which is the dateEditor. For example, on a date field, we can call this outputType: FieldType.dateIso (by default it uses dateUtc as the output):

this.columnDefinitions = [
 {
   id: 'start', name: 'Start', field: 'start',
   type: FieldType.date,
   editor: { model: Editors.date }, 
   type: FieldType.date,              // dataset cell input format
   // outputType: FieldType.dateUs,   // date picker format
   saveOutputType: FieldType.dateUtc, // save output date format
  }
];

So to make it more clear, the saveOutputType is the format that will be sent to the onCellChange event, then the outputType is how the date will show up in the date picker (Flatpickr) and finally the type is basically the input format (coming from your dataset). Note however that each property are cascading, if 1 property is missing it will go to the next one until 1 is found... for example, on the onCellChange if you aren't defining saveOutputType, it will try to use outputType, if again none is provided it will try to use type and finally if none is provided it will use FieldType.dateIso as the default.

Date Picker - Flatpickr Localization

In order to use different locale, you will have to import whichever Flatpickr locale you need. The best place to do these imports is in your App Module so it's global and you do it only once.

import { AngularSlickgridModule } from 'angular-slickgrid';

// load necessary Flatpickr Locale(s), but make sure it's imported AFTER the SlickgridModule import
import 'flatpickr/dist/l10n/fr';

@NgModule({
  declarations: [/*...*/],
  imports: [
    // ...
    AngularSlickgridModule.forRoot({
      // add any Global Grid Options/Config you might want
    })
  ],
  providers: [/*...*/],
  bootstrap: [AppComponent]
})
export class AppModule { }

AutoComplete Editor

The AutoComplete Editor has the same configuration (except for the model: Editors.autoComplete) as the AutoComplete Filter, so you can refer to the AutoComplete Filter Wiki for more info on how to use it.

Select Editors

The library ships with two select editors: singleSelectEditor and the multipleSelectEditor. Both support the multiple-select library, but fallback to the bootstrap form-control style if you decide to exclude this library from your build. These editors will work with a list of foreign key values (custom structure not supported) and can be displayed properly with the collectionFormatter. example 3 has all the details for you to get started with these editors.

Here's an example with a collection, collectionFilterBy and collectionSortBy

this.columnDefinitions = [
  {
    id: 'prerequisites', name: 'Prerequisites', field: 'prerequisites',
    type: FieldType.string,
    editor: {
      model: Editors.multipleSelect,
      collection: Array.from(Array(12).keys()).map(k => ({ value: `Task ${k}`, label: `Task ${k}` })),
      collectionSortBy: {
        property: 'label',
        sortDesc: true
      },
      collectionFilterBy: {
        property: 'label',
        value: 'Task 2'
      }
    }
  }
];

Editor Options (MultipleSelectOption interface)

All the available options that can be provided as editorOptions to your column definitions can be found under this multipleSelectOption interface and you should cast your editorOptions to that interface to make sure that you use only valid options of the multiple-select.js library.

editor: {
  model: Editors.SingleSelect,
  editorOptions: {
    maxHeight: 400
  } as MultipleSelectOption
}

Collection Async Load

You can also load the collection asynchronously, but for that you will have to use the collectionAsync property, which expect an Observable (HttpClient) to be passed.

Load the collection through an Http call

this.columnDefinitions = [
    {
    id: 'prerequisites', name: 'Prerequisites', field: 'prerequisites',
    filterable: true,
    editor: {
      collectionAsync: this.http.get<{ value: string; label: string; }[]>('api/data/pre-requisites'),
      model: Editors.multipleSelect,
    }
  }
];

Modifying the collection afterward

If you want to modify the collection afterward (can be collection or even collectionAsync), you can simply push or modify the collection directly. You just need to find in your Column Definition and Angular-Slickgrid will take care of the rest for you.

For example

  addItem() {
    const lastRowIndex = this.dataset.length;
    const newRows = this.mockData(1, lastRowIndex);

    // wrap into a timer to simulate a backend async call
    setTimeout(() => {
      const requisiteColumnDef = this.columnDefinitions.find((column: Column) => column.id === 'prerequisites');
      if (requisiteColumnDef) {
        const collection = requisiteColumnDef.editor.collection;

        if (Array.isArray(collection )) {
          // add the new row to the grid
          this.angularGrid.gridService.addItemToDatagrid(newRows[0]);

          // then refresh the Filter "collection", we have 2 ways of doing it

          // 1- Push to the Filter "collection"
          collection.push({ value: lastRowIndex, label: lastRowIndex, prefix: 'Task' });

          // or 2- replace the entire "collection"
          // requisiteColumnDef.editor.collection = [...collection, ...[{ value: lastRowIndex, label: lastRowIndex }]];
        }
      }
    }, 250);
  }

Collection Label Prefix/Suffix

You can use labelPrefix and/or labelSuffix which will concatenate the multiple properties together (labelPrefix + label + labelSuffix) which will used by each Select Filter option label. You can also use the property separatorBetweenTextLabels to define a separator between prefix, label & suffix.

Note If enableTranslateLabel flag is set to True, it will also try to translate the Prefix / Suffix / OptionLabel texts.

For example, say you have this collection

const currencies = [ 
  { symbol: '$', currency: 'USD', country: 'USA' }, 
  { symbol: '$', currency: 'CAD', country: 'Canada' }
];

You can display all of these properties inside your dropdown labels, say you want to show (symbol with abbreviation and country name). Now you can.

So you can create the multipleSelect Filter with a customStructure by using the symbol as prefix, and country as suffix. That would make up something like this:

  • $ USD USA
  • $ CAD Canada

with a customStructure defined as

editor: {
  collection: this.currencies,
  customStructure: {
    value: 'currency',
    label: 'currency',
    labelPrefix: 'symbol',
    labelSuffix: 'country',
  },
  collectionOptions: {
    separatorBetweenTextLabels: ' ' // add white space between each text
  },
  model: Editors.multipleSelect
}

Collection Label Render HTML

By default HTML is not rendered and the label will simply show HTML as text. But in some cases you might want to render it, you can do so by enabling the enableRenderHtml flag.

NOTE: this is currently only used by the Editors that have a collection which are the MultipleSelect & SingleSelect Editors.

this.columnDefinitions = [
  { 
    id: 'effort-driven', name: 'Effort Driven', field: 'effortDriven',
    formatter: Formatters.checkmark,
    type: FieldType.boolean,
    editor: {
      // display checkmark icon when True
      enableRenderHtml: true,
      collection: [{ value: '', label: '' }, { value: true, label: 'True', labelPrefix: `<i class="fa fa-check"></i> ` }, { value: false, label: 'False' }],
      model: Editors.singleSelect
    }
  }
];

Default Sanitize-Html Options

If you find that the HTML that you passed is being sanitized and you wish to change it, then you can change the default sanitizeHtmlOptions property defined in the Global Grid Options, for more info on how to change these global options, see the Wiki - Global Grid Options. The current defaults are:

sanitizeHtmlOptions: {
    allowedTags: [ 'h3', 'h4', 'h5', 'h6', 'blockquote', 'p', 'a', 'ul', 'ol',
    'nl', 'li', 'b', 'i', 'strong', 'em', 'strike', 'code', 'hr', 'br', 'div',
    'table', 'thead', 'caption', 'tbody', 'tr', 'th', 'td', 'pre', 'iframe', 'span' ],
    allowedAttributes: { '*': ['*'] }
},

multiple-select.js Options

You can use any options from Multiple-Select.js and add them to your filterOptions property. However please note that this is a customized version of the original (all original lib options are available so you can still consult the original site for all options).

Couple of small options were added to suit Angular-SlickGrid needs, which is why it points to angular-slickgrid/lib folder (which is our customized version of the original). This lib is required if you plan to use multipleSelect or singleSelect Filters. What was customized to (compare to the original) is the following:

  • okButton option was added to add an OK button for simpler closing of the dropdown after selecting multiple options.
    • okButtonText was also added for locale (i18n)
  • offsetLeft option was added to make it possible to offset the dropdown. By default it is set to 0 and is aligned to the left of the select element. This option is particularly helpful when used as the last right column, not to fall off the screen.
  • autoDropWidth option was added to automatically resize the dropdown with the same width as the select filter element.
  • autoAdjustDropHeight (defaults to true), when set will automatically adjust the drop (up or down) height
  • autoAdjustDropPosition (defaults to true), when set will automatically calculate the area with the most available space and use best possible choise for the drop to show (up or down)
  • autoAdjustDropWidthByTextSize (defaults to true), when set will automatically adjust the drop (up or down) width by the text size (it will use largest text width)
  • to extend the previous 3 autoAdjustX flags, the following options can be helpful
    • minWidth (defaults to null, to use when autoAdjustDropWidthByTextSize is enabled)
    • maxWidth (defaults to 500, to use when autoAdjustDropWidthByTextSize is enabled)
    • adjustHeightPadding (defaults to 10, to use when autoAdjustDropHeight is enabled), when using autoAdjustDropHeight we might want to add a bottom (or top) padding instead of taking the entire available space
    • maxHeight (defaults to 275, to use when autoAdjustDropHeight is enabled)
Code
this.columnDefinitions = [
  {
    id: 'isActive', name: 'Is Active', field: 'isActive', 
    filterable: true,
    editor: {
      collection: [{ value: '', label: '' }, { value: true, label: 'true' }, { value: false, label: 'false' }],
      model: Editors.singleSelect, 
      elementOptions: {
        // add any multiple-select.js options (from original or custom version)
        autoAdjustDropPosition: false, // by default set to True, but you can disable it
        position: 'top'
      }
    }
  }
];

Perform an action after inline edit

Recommended way

What is ideal is to bind to a SlickGrid Event, for that you can take a look at this Wiki - On Events

Not recommended

You could also, perform an action after the item changed event with onCellChange. However, this is not the recommended way, since it would require to add a onCellChange on every every single column definition (while you can do with 1 onEvent).

Custom Inline Editor

To create a Custom Editor, you need to create a class that will extend the Editors interface and then use it in your grid with editor: { model: myCustomEditor } and that should be it.

NOTE Custom Editor accepts only regular HTML and/or jQuery 3rd party lib. It will not work with any Angular lib or template. I have no time to invest in this and not much use either since all embedded Editors are enough for my usage. However, if you wish to create a PR to support Angular lib/template, I certainly welcome PR (Pull Request).

Once you are done with the class, just reference it's class name as the editor, for example:

Class implementing Editor
export class IntegerEditor implements Editor {
  constructor(private args: any) {
    this.init();
  }

  init(): void {}
  destroy() {}
  focus() {}
  loadValue(item: any) {}
  serializeValue() {}
  applyValue(item: any, state: any) {}
  isValueChanged() {}
  validate() {}
}
Use it in your Column Definition

For Custom Editor class example, take a look at custom-inputEditor.ts

this.columnDefinitions = [
  {
    id: 'title2', name: 'Title, Custom Editor', field: 'title',
    type: FieldType.string,
    editor: {
      model: CustomInputEditor // reference your custom editor class
    },
  }
];

Custom Editor with Angular Components

You can see them in Example 22 which have both Custom Editors & Filters which uses Angular Components. The 2nd column "Assignee" is the column that uses both (it uses ng-select 3rd party lib wrapped in an Angular Components here) and you need to create a Custom Editor like here and use that Custom Editor in your column definition like here.

Personally I don't find this very straightforward and I don't recommend using Angular Components for Editors/Filters as it adds a lot of boilerplate (compare to 1 step with a jQuery Custom Editor) but if you really wish to go that route, it's now possible following the steps shown below.

The steps to use an Angular Component as a Custom Editor are the following:

  1. Create a Custom Editor that will handle the creation or compilation of the Angular Component into a SlickGrid Editors. For that you can take a look at this Custom Editor
  2. Define your Angular Component, for example take a look at this simple ng-select Editor
  3. Use the Custom Editor inside your Column Definitions, for that you can see previous paragraph here

How to prevent Editor from going to the next bottom cell?

The default behavior or SlickGrid is to go to the next cell at the bottom of the current cell that you are editing. You can change and remove this behavior by enabling autoCommitEdit which will save current editor and remain in the same cell

this.gridOptions = {
  autoCommitEdit: true,
  editable: true,
}

OnClick Editor (icon click)

Instead of an inline editor, you might want to simply click on an edit icon that could call a modal window, or a redirect URL, or whatever you wish to do. For that you can use the inline onCellClick event and define a callback function for the action (you could also create your Custom Formatter).

  • The Formatters.editIcon will give you a pen icon, while a Formatters.deleteIcon is an "x" icon
this.columnDefinitions = [
   {
      id: 'edit', field: 'id',
      formatter: Formatters.editIcon,
      maxWidth: 30,
      onCellClick: (args: OnEventArgs) => {
        console.log(args);
      }
   },
   // ...
];

The args returned to the onCellClick callback is of type OnEventArgs which is the following:

export interface OnEventArgs {
  row: number;
  cell: number;
  columnDef: Column;
  dataContext: any;
  dataView: any;
  grid: any;
  gridDefinition: GridOption;
}

Event through Slick Grid object

You can also use the Slick Grid events as shown below

View
<angular-slickgrid gridId="grid2"
     (onAngularGridCreated)="angularGridReady($event.detail)"
     (onCellChange)="onCellChanged($event.detail.eventData, $event.detail.args)"
     (onClick)="onCellClicked($event.detail.eventData, $event.detail.args)"
     [columnDefinitions]="columnDefinitions" [gridOptions]="gridOptions" [dataset]="dataset">
</angular-slickgrid>
Component
  onCellChanged(e, args) {
    this.updatedObject = args.item;
    this.angularGrid.resizerService.resizeGrid(10);
  }

  onCellClicked(e, args) {
    const metadata = this.angularGrid.gridService.getColumnFromEventArguments(args);

    if (metadata.columnDef.id === 'edit') {
      this.alertWarning = `open a modal window to edit: ${metadata.dataContext.title}`;

      // highlight the row, to customize the color, you can change the SASS variable $row-highlight-background-color
      this.angularGrid.gridService.highlightRow(args.row, 1500);

      // you could also select the row, when using "enableCellNavigation: true", it automatically selects the row
      // this.angularGrid.gridService.setSelectedRow(args.row);
    } else if (metadata.columnDef.id === 'delete') {
      if (confirm('Are you sure?')) {
        this.angularGrid.gridService.deleteDataGridItemById(metadata.dataContext.id);
      }
    }
  }

Validators

Each Editor needs to implement the validate() method which will be executed and validated before calling the save() method. Most Editor will simply validate that the value passed is correctly formed. The Float Editor is one of the more complex one and will first check if the number is a valid float then also check if minValue or maxValue was passed and if so validate against them. If any errors is found it will return an object of type EditorValidatorOutput (see the signature on top).

Custom Validator

If you want more complex validation then you can implement your own Custom Validator as long as it implements the following signature.

export type EditorValidator = (value: any, args?: EditorArgs) => EditorValidatorOutput;

So the value can be anything but the args is interesting since it provides multiple properties that you can hook into, which are the following

export interface EditorArgs {
  column: Column;
  container: any;
  grid: any;
  gridPosition: ElementPosition;
  item: any;
  position: ElementPosition;
  cancelChanges?: () => void;
  commitChanges?: () => void;
}

And finally the Validator Output has the following signature

export interface EditorValidatorOutput {
  valid: boolean;
  msg?: string | null;
}

So if we take all of these informations and we want to create our own Custom Editor to validate a Title field, we could create something like this:

Component

const myCustomTitleValidator: EditorValidator = (value: any, args: EditorArgs) => {
  // you can get the Editor Args which can be helpful, e.g. we can get the Translate Service from it
  const grid = args && args.grid;
  const columnDef = args.column;
  const dataContext = args.item;
  const gridOptions = (grid && grid.getOptions) ? grid.getOptions() : {};
  const i18n = gridOptions.i18n;

  if (value == null || value === undefined || !value.length) {
    return { valid: false, msg: 'This is a required field' };
  } else if (!/^Task\s\d+$/.test(value)) {
    return { valid: false, msg: 'Your title is invalid, it must start with "Task" followed by a number' };
    // OR use the Translate Service with your custom message
    // return { valid: false, msg: i18n.tr('YOUR_ERROR', { x: value }) };
  } else {
    return { valid: true, msg: '' };
  }
};

and use it in our Columns Definition like this:

this.columnDefinition = [
  {
    id: 'title', name: 'Title', field: 'title',
    editor: {
      model: Editors.longText,
      validator: myCustomTitleValidator, // use our custom validator
    },
    onCellChange: (e: Event, args: OnEventArgs) => {
      // do something
      console.log(args.dataContext.title);
    }
  }
];

Disabling specific cell edit

This can be answered by searching on Stack Overflow Stack Overflow and this is the best answer found.

Based on that, the only difference in Angular-Slickgrid is that all SlickGrid event needs the sg prefix to differentiate SlickGrid Events (sg prefix) versus Angular-Slickgrid Events (asg prefix). More info can be found in this Wiki - Grid & DataView Events.

With that in mind and the code from the SO answer, we end up with the following code.

View

    <angular-slickgrid gridId="grid1"
      [columnDefinitions]="columnDefinitions"
      [gridOptions]="gridOptions"
      (onBeforeEditCell)="verifyCellIsEditableBeforeEditing($event.detail.eventData, $event.detail.args)"
      >
    </angular-slickgrid>

Component

verifyCellIsEditableBeforeEditing(e, args): boolean {
    // you can call `event.preventDefault()` to make cell not editable
    // args contains the dataContext and other Slickgrid arguments
}

Editors on Mobile Phone

If your grid uses the autoResize and you use Editors in your grid on a mobile phone, Android for example, you might have undesired behaviors. It might call a grid resize (and lose input focus) since the touch keyboard appears. This in term, is a bad user experience to your user, but there is a way to avoid this, you could use the pauseResizer

View
<div id="grid1">
   <angular-slickgrid gridId="grid1"
         [columnDefinitions]="columnDefinitions"
         [gridOptions]="gridOptions"
         [dataset]="dataset"
         (onBeforeEditCell)="onBeforeEditCell($event)"
         (onBeforeCellEditorDestroy)="onAfterEditCell($event)"
         (onAngularGridCreated)="angularGridReady($event.detail)">
   </angular-slickgrid>
</div>
Component
 angularGridReady(angularGrid: AngularGridInstance) {
    this.angularGrid = angularGrid;
  }

  onAfterEditCell($event) {
    // resume autoResize feature,  and after leaving cell editing mode
    // force a resize to make sure the grid fits the current dimensions
    this.angularGrid.resizerService.pauseResizer(false);    
    this.angularGrid.resizerService.resizeGrid();
  }

  onBeforeEditCell($event) {
    this.angularGrid.resizerService.pauseResizer(true);
  }
Add a custom footer
