I've created a WPF touchscreen application at work.
When I use a mouse, it behaves as you would expect. However, when using the touchscreen it doesn't behave as it should. It will regularly lag on a PreviewMouseDown touch event, and sometimes won't actually respond at all. Other times it works fine.
Does anybody know what could cause this behaviour, and what can I do to resolve it?
Many thanks
In researching the issue for someone over at EE, I ran across this post. Essentially, the PreviewTouchDown event does not occur until a finger touches the screen and moves. The answering post author goes on to say
To cause the PreviewTouchDown event to occur as soon as a finger touches the screen, set the Stylus.IsPressAndHoldEnabled attached property to false for this element.
This solution was posted in early 2014 and hasn't been rebutted, so it should work.
