 To set up the `DelegateAggregateDescriptor`, use the following properties:
 
 * `ValueLookup`—Defines an `IKeyLookup` instance, which retrieves the value from the underlying `ViewModel` that is used for computing the aggregated value.
+
 * `Function`—Defines an `IAggregateFunction` instance that performs the aggregation of the values as specified by the `ValueLookup` property.
+
 * `Format`—Defines the string format that will be applied over the aggregated value.
 
+The `IAggregateFunction` interface exposes the following methods:
+
+* `GetValue()`—Gets the computed value.
+
+* `Accumulate(object value)`—Applies the function logic to the provided value (the provided value is the extracted value from the `ViewModel`).
+
+* `Merge(IAggregateFunction aggregateFunction)`—Merges this function with another one. Used when calculating Grand Totals.
+
+* `Update(object oldValue, object newValue)`—Updates the aggregate function by removing the contribution of an old value and adding a new value. This allows for efficient recalculation when data items are modified without recomputing the entire aggregation.
+
+* `Clone()`—Clones the current instance of the `IAggregateFunction`.

 The following example uses the `DelegateAggregateDescriptor` and a custom implementation for a `SumIf` function which sums the values in a range that meet a certain criteria:
 
 **1.** Create a class that inherits from the `IKeyLookup` interface. It returns the values of a `Price` property declared in the business model that is of type `double`.

+## Scroll to Item
+
 For implementing programmatic scrolling to a specific item, the DataGrid exposes the `ScrollItemIntoView(object item)` method, which brings the specified data item into view. Note that `ScrollItemIntoView` works in scenarios where the DataGrid Rows are with the same height. For more details, review the article on [setting the .NET MAUI DataGrid rows]({%slug datagrid-row-height%}).
 
 The following example shows how to scroll to the last item of the DataGrid. The code executes on a button click.
 
-```C#
-private void Button_Clicked(object sender, System.EventArgs e)
-{
-    var item = this.vm.Clubs[this.vm.Clubs.Count - 1];
-    this.grid.ScrollItemIntoView(item);
-}
-```
+1. Define the DataGrid in XAML:
+
+<snippet id ='datagrid-scrolling'/>
+
+1. Define the button, which will execute the scroll-to-item action:
+
+<snippet id ='button-scrolling-to-item'/>
+
+1. Add the `telerik` namespace:
+
+`xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"`
+
+1. 1. On button click, call the `ScrollItemIntoView` method:

+
+## Scroll to Column
+
+For implementing programmatic scrolling to a specific column, the DataGrid exposes the `ScrollColumnIntoView(DataGridColumn column)` method, which brings the specified column into the visible viewport.
+If the column is frozen or not part of the grid, no scrolling will occur. The scrolling operation adjusts the horizontal scroll position to make the column visible while maintaining the current vertical scroll position.
