If parent element have gesture and child element have touch effect disabled the child element override parent's gesture

[KyrillosS25]

Hello,
I have 2 stacklayout the parent stack have tap gesture and child stack have touch effect with "IsAvailable = 'False'", when tapping on child stack nothing happens.

could I add/remove touch effect form code behind?

Code :
`

<StackLayout BackgroundColor="Red" HeightRequest="100" WidthRequest="100"> 

    <StackLayout  BackgroundColor="Blue" HeightRequest="50" WidthRequest="50" 
                     touch:TouchEff.NativeAnimation="False"
                     touch:TouchEff.IsAvailable="False"
                     touch:TouchEff.NativeAnimationShadowRadius="10"
                     touch:TouchEff.NativeAnimationColor="Gray">
        
    </StackLayout>
    <StackLayout.GestureRecognizers>
        <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"></TapGestureRecognizer>
    </StackLayout.GestureRecognizers>
</StackLayout>

Try to set InputTransparent to your child StackLayout

That's not TouchEff problem. If you remove TouchEffect at all and just leave a child stack layout the behavior will remain the same

I tried it and got the same behavior

I removed TouchEff from child stack and got the tapped event of the parent, I think that TouchEff somehow override the parent event event if "IsAvailable='False'"

`

    <StackLayout  BackgroundColor="Blue" HeightRequest="50" WidthRequest="50" 
                  
                     >
        
    </StackLayout>
    <StackLayout.GestureRecognizers>
        <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"></TapGestureRecognizer>
    </StackLayout.GestureRecognizers>
</StackLayout>

Have you tried to set InputTransparent = true?

[KyrillosS25]

yes

[AndreiMisiukevich]

Confirmed that's a bug.

Well, there is a workaround. You can remove the effect from code

var effects = view.Effects.OfType<TouchEff>().ToArray();
foreach (var effect in effects)
    view.Effects.Remove(effect);

okay thanks, I'll try that.

@AndreiMisiukevich
the workaround worked. but can I add effects to view from code instead of removing them ?

Yes, sure you can :)

view.Effects.Add(new TouchEff());
TouchEff.SetCommand(view, new Command()); // etc.

Now works fine with IsAvailable=False
