PointerRoutedEventArgs.Pointer is null?

Postby takabo » Mon May 11, 2020 12:01 am

Hi, I'm trying to create a custom control using Windows.UI.Xaml.Controls.Canvas.
I want to do something different with touch, mouse click, and pen.
So, I tried to use PointerRoutedEventArgs.Pointer.PointerDeviceType in PointerPressed event, but Pointer is null.

Is it impossible to judge touch or mouse click?

Hi,

The Pointer property is indeed never assigned at the moment:
https://github.com/OpenSilver/OpenSilve ... entArgs.cs

To add additional information such as the pointer type, one needs to retrieve it from "jsEventArg" (search for "jsEventArg" in the class above to see some examples).

Thanks for the answer.
It seems difficult for me to fix it, so I give up.
