Hi Team,

I have an issue with RadCombobox.
Currently we are using Telerik Version - 2015.3.1111.35 and Upgraded .NetFramework 3.5 to .NetFramework 4.8.

Tested in IE,edge and chrome - Not working.

Radcombobox dropdown click events are not firing after apppool changed to 4.0 for the first postback and 

It works for other controls in further postbacks.

Can anyone please help on this?

Hi Kumar,

Can you confirm that there are no any JavaScript errors thrown on the page when the problem occurs?

If there are no such, please, send me the problematic RadComboBox for ASP.NET AJAX setup as well as the web.config of you application and I will examine the issue further.

Hello Sachita,

RadComboBox.Net2.dll is part of our classic controls which are deprecated about 10 years ago. You can see how to migrate the Classic RadComboBox to RadComboBox for ASP.NET AJAX here:

https://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/migrating-from-radcombobox-classic-to-asp.net-ajax-version
