I need some help here.
I have a page which I am using the ToolkitScriptManager for the use of some AJAX Calendar Control Extenders, and that works fine.
Where I am running into a problem is using the UpdatePanel. I am not getting a partial or any postback on a listbox control.
I have tried adding the regular ScriptManager and I get errors and when I have both of them loaded, ToolkitScriptManager and ScriptManager, I get an error saying that you can only have one Scriptmanager on the page.
Thanks in advance
