What event should be used to handle "clicking" a button in a WPF application on a touchscr-CodePudding

I am developing a solution that will be used solely on touch computers. Should I use Click, TouchDown, PreviewTouchDown to listen to the event of clicking the button on the touchscreen using touch? Originally I was using Click but I noticed in some cases that the event didnt fire on first finger tap on the touch screen and had to touch it again to fire. I am using .NET 4.8. Thanks!

CodePudding user response：

If you handle the TouchDown and also set the Stylus.IsPressAndHoldEnabled attached property of the Button to false, the event should be raised as soon as the finger touches the screen:

<Button Content="Touch" TouchDown="Button_TouchDown" Stylus.IsPressAndHoldEnabled="False" />

By default and as stated in the docs, the event doesn't occur until a finger touches the screen and moves.
