sfChipGroup SelectionChanged event not firing for Trigger type with ItemTemplate

[Ben Fidge]

Hi

This is a follow for threadhttps://www.syncfusion.com/forums/156942/sfchipgroup-selection-indicator-not-showing-when-using-a-custom-itemtemplate

I downloaded the sample in that thread, as was having the same problem using a chip template, and it works fine

However if you upgrade the project use Syncfusion v19.1.0.55, Xamarin Forms v5.0.0.2012, and target Android 10 (API 29), it no longer works.

The `SelectionChanged` event doesnt get triggered and you can't change the state of the selected items. Removing the ItemTemplate and accompany sfChip, selection/deselection works again

Hi Ben, 

 

Greetings from Syncfusion support.  

 

We would like to let you know that we have enabled touch/mouse recognizer support for ChipGroup’s ItemTemplate. So, the touch was handled by template element instead of ChipGroup.  

 

Release notes: https://help.syncfusion.com/xamarin/release-notes/v18.4.0.30?type=all#sfchipgroup  

 

And we can achieve the recommended behavior by setting InputTransparent as true for template element.  

 

<buttons:SfChipGroup.ItemTemplate> 

    <DataTemplate> 

        <StackLayout Orientation="Horizontal" InputTransparent="True"> 

            <buttons:SfChip WidthRequest="40" 

                            ShowSelectionIndicator="{Binding IsChecked}" > 

            </buttons:SfChip> 

        </StackLayout> 

    </DataTemplate> 

</buttons:SfChipGroup.ItemTemplate> 

 

 

 

Regards, 

Saravanan.
