Simple Dialog

[AnthonyLatty]

This is more of a question than a issue, how do i get the click events on each of the string in

MaterialDialog.Instance.SelectActionAsync()

Hi. Unfortunately you can't. Once a choice is clicked, the dialog dismisses and returns the string that was selected. May I ask why you needed the click events and what are you trying to achieve?

[AnthonyLatty]

Hi. What i am trying to achieve is the click event of one dialog triggers a next dialog. So i taught there was a click event that was associated with the Dialog control

[contrix09]

You can check the returned string value of the dialog. It returns string.Empty if the dialog was dismissed other than when a choice was clicked. If the string is not empty, then show the other dialog.

This is what i am attempting to do :

var actions = new string[] { "Test1", "Test2" };

var result = MaterialDialog.Instance.SelectActionAsync("Select an option", actions);
if(actions[0] == "Test1"
{
   //Do something
}
else
{
    //Do something else
}

Hi, my mistake. SelectActionAsync returns only the index of the selected choice. If the dialog was dismissed, it returns -1. You need to detect the negative index to avoid an exception.

var actions = new string[] { "Test1", "Test2" };
var result = MaterialDialog.Instance.SelectActionAsync("Select an option", actions);

if(result >= 0)
{
    switch(actions[result])
    {
        case "Test1": 
              MethodForSomething();
              break;
        case "Test2": 
              MethodForSomethingElse();
              break;
    }
}

You can also use this.

var actions = new string[] { "Test1", "Test2" };
var result = MaterialDialog.Instance.SelectActionAsync("Select an option", actions);

switch(result)
{
    case -1:
          MethodForNoAction();
          break;
    case 0: 
          MethodForSomething();
          break;
    case 1: 
          MethodForSomethingElse();
          break;
}

Would i have to Dispose() of the previous dialog to see the new one?? I added a method with the same code:

var actions = new string[] { "Test3", "Test4" };

var result = MaterialDialog.Instance.SelectActionAsync("Select an option", actions);

and i am not seeing this dialog when i tapped on "Test1"

[contrix09]

No need to call dispose, the dialog automatically disposes when it is dismissed.
Add the await keyword before calling the method.

var result = await MaterialDialog.Instance.SelectActionAsync("Select an option", actions);

This is the code i have

var actions = new string[] { "Residents 1", "Residents 2" };

var result = await MaterialDialog.Instance.SelectActionAsync("Select an option", actions);

switch (result)
{
   case -1:
       break;
   case 0:
       var resident1 = new string[] { "Home", "Away" };
       var result1 = await MaterialDialog.Instance.SelectActionAsync("Residents 1", resident1);
       break;
   case 1:
       var resident2 = new string[] { "Local", "Away" };
       var result2 = await MaterialDialog.Instance.SelectActionAsync("Residents 2", resident2);
       break;
}

No new dialog appears

Hi. After some investigation, I saw the problem. The result is being returned but before showing the next dialog, it was dismissed immediately since the disappearing animation of the first dialog was still not finished.

[AnthonyLatty]

Ok thats good because i taught i was misusing the library. Is is possible to allow the animation of the first dialog to disappear on click?

[contrix09]

Yes, I already have a solution. The dialog will first dismiss before it will return the result. The current implementation is that the result was first returned before dismissing the dialog.

To ensure that the old dialogs are removed from the modal stack before returning a result and showing another dialog of the same type, a delay of 100 milliseconds, which is the disappearing animation duration of all dialogs, will be seen.

I can release a new version may be later this day.

[AnthonyLatty]

Will test when its released

[AnthonyLatty]

Tested it, works as expected. Any further issue i will update accordingly.
