Ajax Error with Microsoft's ReportViewer

[Robert O'Dell]

I'm required to use rdl or rdlc for my reports, so when presenting I use the Microsoft ReportViewer control as I believe that Telerik's ReportViewer does not support those extensions.  My problem is I have a checkboxlist that I need to populate based on a drop down list.  These controls are in RadMultiPage.  I've surrounded the two fields with a RadAjaxPanel.  When I run the page, it comes up correctly, the Ajax works in that I can populate the checkboxlist. But then when I press the button to build the report, I get the following error.

Specified argument was out of the range of valid values.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

[ArgumentOutOfRangeException: Specified argument was out of the range of valid values.] Microsoft.Reporting.WebForms.ReportViewer.set_CurrentPage(Int32 value) +137 Microsoft.Reporting.WebForms.ReportViewer.ClientSidePageNumberChanged(Object sender, EventArgs e) +69 System.Web.UI.WebControls.HiddenField.OnValueChanged(EventArgs e) +111 System.Web.UI.WebControls.HiddenField.RaisePostDataChangedEvent() +31 System.Web.UI.WebControls.HiddenField.System.Web.UI.IPostBackDataHandler.RaisePostDataChangedEvent() +10 System.Web.UI.Page.RaiseChangedEvents() +165 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1485

If I remove the RadAjaxPanel, the page works correctly.  The ReportViewer is not within the RadAjaxPanel and in fact is in a different RadPageView.  Do you have any thoughts on this?
Thanks,

Hi Robert,

Could you please test the application by using regular asp UpdatePanel instead of RadAjaxPanel and let me know whether the problem still persists?
