Hello,
I have a XamMap with a layer which consists of a number of points and I need to output a dialog at this point's position by ElementClick. I can get WorldRect of the clicked MapElement. How can I convert it to window coordinates? Or is there any other way to get coordinates of the clicked point?
Thank you.
Hi Sergey,The following article provides information on point coordinates projecting to xamMap: link. In your case, you want to unproject the coordinates, so UnprojectFromMap could be used, for example: private void theMap_ElementClick(object sender, MapElementClickEventArgs e) { Point pt1 = theMap.MapProjection.UnprojectFromMap(new Point(e.Element.SymbolOrigin.X, e.Element.SymbolOrigin.Y)); ... }Best Regards,Milana Zhileva
Thanks for your response. But how can I get window coordinates of the clicked element?
Hi Sergey,If I am able to understand your scenario correctly, then you could try unprojecting element's WorldRect's coordinates like this:Point pt1 = theMap.MapProjection.UnprojectFromMap(new Point(e.Element.WorldRect.X, e.Element.WorldRect.Y));
or use its Width and Height for a more precise calculation.Hope this helps,Milana Zhileva
Thanks a lot for your help!
Hello Sergey,
I have been further looking into your requirement and have managed to use some internal code to achieve the functionality you wanted. Here is a sample project (XamMap_translate_from_map.zip) that shows how you can pin point a MapElement’s window location.
Please let me know, if you require any further assistance on the matter.
I have been looking into your requirement and even though I managed to get a list of the Paths representing the MapElemenets there doesn’t seem to be a way to relate them to an element outside the XamMap.

Thank you for your request.
Regarding your requirement I can suggest you either use the mouse positions at the time of the click for your new window, or better yet create a value template of your liking with an actual ToolTip: http://help.infragistics.com/NetAdvantage/WPF/2012.2/CLR4.0/?page=xamWebMap_Customize_Map_with_Value_Templates.html , which would not interfere with your dragging.
Please let me know, if I can be of any further assistance on the matter.
Using the code you provided I can get geodetic coordinates of the MapElement. But I need to obtain window coordinates of the clicked element (in my case elements' width and height equals 0) so that I could output seperate window in the same position as tooltip appears. Also I need to take into account that the map can be dragged. Is it possible to achieve such behaviour?
