ContentElement.ReleaseMouseCapture Method

Releases the mouse capture, if this element held the capture.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

public void ReleaseMouseCapture()

Implements

IInputElement.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 void MouseDownHandler(object sender, MouseButtonEventArgs e)
{
    ContentElement el = (ContentElement)sender;
    if (!el.IsEnabled) return;
    e.Handled = true;
    el.CaptureMouse();
    _point = e.MouseDevice.GetPosition(el); 
}

private void MouseUpHandler(object sender, MouseButtonEventArgs e)
{
    ContentElement el = (ContentElement)sender;
    if (!el.IsEnabled) return;
    e.Handled = true;
    el.ReleaseMouseCapture();
}
