I have a report with a datetime parameter and it is in a ReportViewer control (remote mode). Whenever the parameter is changed, the following error message pops up:
'this._postbackSettings.async' is null or not an object
The report shows up fine after the error window is clicked away. I believe I can suppress the window by disabling script debugging, but I need this and users may have the enabled also. The the report is viewed directly on the report server, everything
Any tip to get rid of the error message will ge greatly appreciated.

The porblem is gone after removing ScriptManager and UpdatePanel. This is reproducible. Please let me know if you can use a Datetime parameter which comes with dropdown calendar while using UpdatePanel.

I had this same error on my site but wasn't using the AjaxControlToolkit.
Here's what I had to do to fix it...
