just like the Question title, i need add markers on my Google Map Canvas using AJAX but calling methods on ASP.net server side.
i tried with update panels , and calling javascript functions on server side using ScriptManager.RegisterClientScriptBlock, but it didn't work.
(even when I put the map in a container of updatepanel, it disappeared and did not return to show pictures)
i'd like to create a custom asp user control which can make those asyncronic calls and handle map events on server side.
How I can deal with this problem? There are many solutions that confuses me and I do not know where to start
