Move the Cursor Away From the RadButton Control

Environment

Product Version	2020.3.915
Product	Buttons for WPF

Description

Using a device that supports both mouse and touch input, can cause the mouse to go to the tapped location, causing the button to apply a trigger for the IsMouseOver property.

Solution

Subscribe to the TouchUp event of the RadButton control, and use the Win32 API to manually move the cursor away from the button.

[DllImport("User32.dll")] 
private static extern bool SetCursorPos(int X, int Y); 
 
private void RadNumericUpDown_TouchUp(object sender, TouchEventArgs e) 
{ 
    SetCursorPos(0, 0); 
} 

<DllImport("User32.dll")> 
Private Shared Function SetCursorPos(ByVal X As Integer, ByVal Y As Integer) As Boolean 
 
Private Sub RadNumericUpDown_TouchUp(ByVal sender As Object, ByVal e As TouchEventArgs) 
    SetCursorPos(0, 0) 
End Sub
