I try to use a Reportviewer 10.0.0.0 in a project that uses AJAX controllers. If I first add a ScriptManager and a reportviewer there is no problem, the Reportviewer is shown. If I then add another AjaxToolboxScript I need to use the ToolkitScriptManager. But if I use the ToolkitScriptManager the page starts with depugger error:
"Microsoft JScript runtime error: Sys.ArgumentNullException: Value cannot be null.Parameter name: panelsCreated"
(There is no poblem to use the RepoertViewer, but the error reoccur every postback.)
If I then change back to standard ScriptManager the same error occur. I have to generate a new project before I get rid of the error, a project without ToolkitManager.
I think this is a problem with AJAX toolkit, any thoughts?
