Identifying Dynamically created ImageButton click and its properties in Xamarin.forms

Question

I have used Xamrin.forms.labs to create Imagebutton in shared code. Number of imagebuttons varies according to the number of elements in the list. My questions are

1. How can I identify which button is clicked? (I need the text of the Imagebutton for identification)
2. I have to change the image to Source_on.png on the first click of the image button and change back to Source.png on second click. (Just like select and unselect)

How can I acheive it??

The code I have used to create ImageButtons is given below.

            StackLayout Holder = new StackLayout {
            HorizontalOptions=LayoutOptions.FillAndExpand,
            VerticalOptions=LayoutOptions.Center,
            Orientation=StackOrientation.Horizontal,
            Spacing=2,
            };

        foreach (var options in list)
        {

                var Icon = new ImageButton () {
                    Source=Source.png,
                    BackgroundColor=Xamarin.Forms.Color.Transparent,
                    HorizontalOptions=LayoutOptions.CenterAndExpand,
                    VerticalOptions=LayoutOptions.CenterAndExpand,
                    Orientation=Xamarin.Forms.Labs.Enums.ImageOrientation.ImageOnTop,
                    Text=labeltxt,
                };

                Icon.Clicked += OnSelected;

                Holder.Children.Add (Icon );

            }
        }

Providing a helpful link or sample code will be really helpful.. Thanks in Advance..

Answer 1

It would help a lot if you share the code of your ImageButton .

That being said... if your ImageButton has a Command property it would also have a CommandParameter property. If it doesn't have that - make them.

You'd set the CommandParameter property with some ID and then bind the Command to the same code, such as

ImageButton icon = null;
icon = new ImageButton{
...
  Command= new Command((tag)=>{
     icon.Source = ImageSource.FromFile("...");// see other .FromXYZ methods too
  },
  CommandParameter="<your tag here>",
}

BUT... before you do all of that check out the Xamarin.Forms.Labs , there's an ImageButton there already and you can add that project from NuGet by searching for "Xamarin Forms Labs" in the package manager
