Mouse capture state is related to in-process drag-and-drop operations.

The following example turns the mouse capture state on or off based on whether the mouse is already captured for the element.

If mouse capture is elsewhere, the mouse capture is set to that element. If the element had mouse capture, it is cleared by calling Mouse.Capture with a null input.

private void CaptureMouseCommandExecuted(object sender, ExecutedRoutedEventArgs e)
    MessageBox.Show("Mouse Command");
    IInputElement target = Mouse.DirectlyOver;
    target = target as Control;
    if (target != null)
        if (!target.IsMouseCaptured)
