n displays map on right and buttons on left but with RadAjax Manager my map panel is empty. How can I ajaxify my application with Ajax Manager. Given below is my code and mark up.

I have another issue with RadAjax manager. I wanted to set "Initiater control" and "Update control" using visual builder but I cannot see my user control in visual builder. Is it normal or am I missing something?

Thanks

Hello Prava,

I noticed that you add MapDivSplitter as updated control into the RadAjaxManager settings. However this control have VisibleDuringInit="false" set for the splitter. Note that adding initially invisible controls into the ajax settings is not supported scenario. The initiator and target controls should always be visible on the page. Therefore I suggest you to add in the ajax setting a container which is always visible on the page instead of the splitter.
Regarding the property builder question you have - yes not seeing the UserControl into the PropertyBuilder is normal behavior. You could use only the user control's container in the designer settings.
