I am trying to display a ThinkGeoMap inside radsplitter and ajaxify it using RadAjax Manager. The map works fine if I use Asp.Net UpdatePanels. Once I remove Updatepanels and use RadAjax Manager my map is invisible.

If I replace map with Image everything works fine. Why  am I having problem with a dynamic control like map? Given below is my code and mark up.

Hi Prava,

Does it makes any difference if you add an ajax setting where the Map1 control updates itself?
Also try calling the openMap() method on each Page_Load instead of on initial page load. Note that when controls are added dynamically with ajax, they should be recreated on each page load.

Let me know how it goes.

Best wishes,
