MouseLeftButtonDown Event at Runtime

AgatinoLa_Rosa — Thu, 14 Apr 2011 18:02:02 GMT

I have a GraphicsLayer managed at runtime, it is not coded in xaml. I have tried to add a click event
in the InitializeComponent() section of the cs for this layer:
myGraphicsLayer.MouseLeftButtonDown +=new GraphicsLayer.MouseButtonEventHandler(myGraphicsLayer_MouseLeftButtonDown);

and I get of delegate error. Any suggestion?

Difficult to guess anything without seeing the handler.

I am not sure if I follow you. Do you mean for handler:

private void myGraphicsLayer_MouseLeftButtonDown(object sender, MouseButtonEventHandler args)
        {
            ///zoom to selected graphic
        }

The second argument of your handler should be of type GraphicMouseButtonEventArgs

 
private void myGraphicsLayer_MouseLeftButtonDown(object sender, GraphicMouseButtonEventArgs args)
        {
            ///zoom to selected graphic
        }

This has been changed a few time ago, hence the confusion.
