custom user control added to a parent panel not firing Pointer Events

Question

Hi,

i have a custom control derived from UserControl like the following - Note: i dont have a Xaml control defined for this, this is all done in C++ code.

public ref class ToolUserControlBase: public UserControl { //other functions omitted for brevity }

and in the constructor of this, i am doing the following 

PointerPressed += ref new PointerEventHandler(this, &ToolUserControlBase::OnPointerPressed);	
Loaded += ref new RoutedEventHandler(this, &ToolUserControlBase::OnLoaded);

i am adding this control to a Grid element (which raises the OnLoaded event)

in the OnLoaded event i am setting the width and height of the control to the parents width and height

the problem is that the pointer events are not firing at all on this user-control.

i tried checking the visibility , IsHitTestVisible , IsEnabled properties and everything is fine. 

Note: If i create a Xaml control derived from this usercontrol and then add that xaml control to parent then things work fine but if i just directly create and add this user-control then the events dont fire at all.

Am i missing anything here? do i need to initialize any appropriate members variables of the UserControl in the constructor ? 

Thanks,

Hi Raj,

Can you please provide a minimal sample demonstrating the working and non-working scenarios so we can see more clearly what your code is doing?
