[EswaranSyncfusion]

Description

I used ContentView to construct a custom control, and I override the OnTouchEvent event to handle touch input. All are worked as expected. But after I have added a grid layout with a tap gesture as a content of my control, the OnTouchEvent override method in my CustomControl not getting called when I try to interact with grid layout. The OnTouchEvent override method calls properly if I remove the tap gesture from the grid.

Steps to Reproduce

1. Run the attached sample
2. Touch the content view
3. Check whether the OnTouchEvent is called or not.

Expected Behavior

The OnTouchEvent override method should be called.

Actual Behavior

The OnTouchEvent is not called.
