I am using SSRS Report Viewer Control (VS2008) within a RADAJAXPanel. Parameters to the report are passed from controls within the same RADAJAXPanel. If a parameter value is changed, all text content within the report refreshes but not the charts when AJAX is enabled. The updated charts are visible if AJAX is disabled or after a manual IE page refresh.

This issue only occurs in IE7 and IE8. AJAX refresh in IE6 works fine.

Hello Sattish,

Could you please test the application by using regular asp UpdatePanel instead of RadAjaxPanel and verify of it behaves the same way?

Thanks for the suggestion. This is what I tried out:
1) Used UpdatePanel instead of RADAJAX panel: Issue still exists
2) Updated the SSRS Report Viewer Control to 2010 version and used UpdatePanel: Issue does not occur. This fixes the images.
3) Updated the SSRS Report Viewer Control to 2010 version and used RADAJAX panel: I am getting a javascript exception and the report does not get updated. The exception that I get is:
    "Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object."

Is this possibly an issue with the older version SSRS Report Viewer control? If upgrading the SSRS control is the only option, is there any additional configuration changes needed for RADAJAX panel to work with the new Report Viewer Control?

Thanks in advance

Hello Sattish,

I tried to replicate the described error using ReportViewer2010 and RadAjaxPanel on my side but to no avail. Please find attach small runnable application which represents the correct behavior of this scenario. Test it locally and let me know what the difference in your side is.
