we have a RadGrid which Has 1 RadCombo with LoadonDemand and 2buttons to "ADD" and "DEL" Rows
to avoid Postback we are using RadAjaxManager on RadGrid
Issue here is while clicking Add button for first 5 times we are able to ADD records.
after that if we click ADD button it is not firing one more thing we observed id before clicking ADD button if we open the RadComboBox it is throwing error like "The Target <ID> for the Callback could not be found or did not implement IcallBackeventHandler"
same thing is happening when we use ASP UpdatePanel
if we Remove the RadAjaxManager or UpdatePanel every thing is working Fine.
Please Help! Quick reply will be highly appreciated
