add MouseButtonEventArgs to userControl in wpf-CodePudding

I have a usercontrol. This usercontrol has a button that when you click on it, It has to get the mouse position for mainWindow and show a message. the problem is that for getting the mouse position, The event has to be a "MouseButtonEventArgs" event but you can only add "RoutedEventArgs" to user control.

CodePudding user response：

You can get the mouse position relative to your app's MainWindow whenever you want and wihtout using event-handlers at all..

Point mousePosition = Mouse.GetPosition(Application.Currect.MainWindow);

If you want the position relative to some other UIElement

// element can be usercontrol, window dialog, etc..
// it would return negative x,y values if the mouse is out of the element
Point mousePosition = Mouse.GetPosition(element);
