    Hello,

    I have a radGrid inside a XmlHttpPanel and when I call panel.set_value() I am getting the following error:

    XmlHttpPanel Callback Loading error:
    Exception=Script control 'rfltMenu' is not a registered script control.
    Script controls must be registered using RegisterScriptControl() before
    calling RegisterScriptDescriptors().
    Parameter name: scriptControl


    I have downloaded and installed the latest build ( 2009_2_927) which seems to have fixed a similar error I was getting before with the GoToPageTextBox. 

    Thanks

    Ernie

    Hi Ernie,

    Can you please send me the source code of the project you are testing? I do not seem to get this error on my side, when testing with the latest internal build (2009_2_928).

    Thanks Pero

    After reading the documentation a bit more thoroughly I came to the conclusion that the XmlHttpPanel was not the right control for a grid with AllowFilteringByColumn set to "True" and have gone back to using a radAjax request.  

    BTW the version I was using was 927.35 (which was the latest on the day).  I have a stripped down version of the source code which I can send if it helps.  Please let me know how to send it as the Attach file option below only accepts image files.

    Cheers

    Hi Pero, 

    I am experiencing the same error while enabled AllowFilteringByColumn  for RadGrid in RadXMLHttpPanel.

    As Ernie says "After reading the documentation a bit more thoroughly I came to the conclusion that the XmlHttpPanel was not the right control for a grid with AllowFilteringByColumn set to "True" and have gone back to using a radAjax request.  "

    Where in documentation I see, Filtering is not supported by RadXMLHttpPanel for RadGrid?

    Thanks
    Hari

    Hi Hari,

    We haven't explicitly said that filtering of the RadGrid is not supported by the RadXmlHttpPanel, but the simple fact that the RadXmlHttpPanel does not load and save Viewstate during updates, causes the RadGrid's filtering to not work correctly. RadGrid depends on the Viewstate and many of its features will not work if it is not saved and loaded correctly.

    Kind regards,
