Public Sub ReleaseMouseCapture

If this element did not hold the capture, calling this method has no effect. Consider checking the value of IsMouseCaptured before you call this method.

The following handler captures or releases mouse capture according to mouse button states. The example shows how to use captured mouse movement for alternative purposes other than moving the mouse pointer in the UI.

Private Sub MouseDownHandler(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
	Dim el As ContentElement = CType(sender, ContentElement)
	If Not el.IsEnabled Then
		Return
	End If
	e.Handled = True
	el.CaptureMouse()
	_point = e.MouseDevice.GetPosition(el)
End Sub

Private Sub MouseUpHandler(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
	Dim el As ContentElement = CType(sender, ContentElement)
	If Not el.IsEnabled Then
		Return
	End If
	e.Handled = True
	el.ReleaseMouseCapture()
End Sub
