XamDataChart raises no PreviewMouseDown / MouseDown event when using a touch screen
posted

Hi,

 

I am using a XamDataChart in my WPF application and I am using Infragistics WPF 2015.2.

When I am using the XamDataChart with the mouse all events are fired as expected.

When I am doing the same with a touch screen then I expect the same behavoir like for a standard WPF control (e.g. label) but with the XamDataChart I am missing the PreviewMouseDown / MouseDown event.

Standard behavior on touch:

  • PreviewStylusDown
  • StylusDown
  • PreviewTouchDown
  • TouchDown
  • PreviewMouseDown
  • MouseDown

XamDataChart behavior on touch:

  • PreviewStylusDown
  • StylusDown
  • PreviewTouchDown
  • TouchDown

Is this an intentional behavior (e.Handled = true in TouchDown?) or a bug in XamDataChart? If it is an intentional behavior is it possible to suppress this behavior?

Thank you in advance

André
