get mouse poisition when hovering map element
posted

I am trying to get a silverlight popup to display near the mouse when I hover over a map element.

Is there a way of getting the mouse position from the elements symbol position?

    this is not exposed as a feature of the map; however, you can use the RenderTransform of the Map Viewport's RootCanvas to translate the coordinate.

         private void XamWebMap_ElementHover(object sender, MapElementHoverEventArgs e)
            {
                XamWebMap theMap = (XamWebMap)sender;
                Point pos = e.Element.ActualSymbolOrigin;
                pos = theMap.Viewport.RootCanvas.RenderTransform.Transform(pos);
                Popup pop = new Popup();
                pop.Child = new TextBlock() { Text = "hello" };
                pop.HorizontalOffset = pos.X;
                pop.VerticalOffset = pos.Y;
                pop.IsOpen = true;
            }

    alternatively, you could just use the MouseMove event, and avoid referencing any MapElement.
