Hi guys,
I would like to get the 4 coordinates for the displayed map on RadMap
Top Right (x, y) , Top Left (x, y) , Bottom Left (x, y) , Bottom Right (x, y)
those values should change different when a user zoom in/out, or move the map with mouse.
is there a way to do that?

Hello, Ammar,
The MapElement.ViewportChanged event allows you to detect when the map view is changed. In the ViewportChangedEventArgs you have access to the Viewport from where you can get its Center property giving you the center PointG. The CenterPixel gives you the center PointL. The Viewport offers the Viewport property which returns the RectangleG of the current view. Thus, you can get the necessary information for the map boundaries, e.g. by using the Viewport.Viewport.NorthWest and Viewport.Viewport.SouthEast properties. The Viewport also offers the ViewportInPixels property giving the RectangleL (viewport in pixels).
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
