In my project I am using telerik RadComboBox version 2.6.0, RadAjax.Net2.dll version 1.6.0 and ajaxcontroltoolkit version 3.0.20820.31333 and .net 3.5
- on my page I have a asp.net drop down control inside a ajax update panel,and the second update panel which contain the AsyncPostBackTrigger attached with the drop down to update the content of the second update panel.
- RadComboBox inside the RadAjaxPanel.
- when the selectedindex changed of drop down is fired I got the error “sys.WebForms.PageReuestManagerServerErrorException: Ambiguous match found”.
Can you please let me know what is the issue.
