    i created a page similiar to the demo in http://demos.telerik.com/aspnet-ajax/xmlhttppanel/examples/clientsidecontentload/defaultcs.aspx

    made a few changes in that 

    1. replaced the  asp:Repeater  with a radgrid with the same properties as the radgrid1 in the demo 
    2. added an event RadGrid2_NeedDataSource for the radgrid2 
    3. added a textbox in the page and stored the value got from XmlHttpPanel_ServiceRequest in the page.
    4. the second grid has a pagesize of 10. 

    it works without any problem if the 2nd grid has less than 10 records or if the paging is set to false. but if the paging is set to true and if the record count is more than 10(the pagesize) , it shows the following error

    eScript control 'PageSizeComboBox' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
    Parameter name: scriptControl

    this is my code

    Hi Jikesh,

    This is a known issue of the XmlHttpPanel, when the Grid is using advanced paging. The complexity of the RadGrid does not allow to make it work correctly in all scenarios with the RadXmlHttpPanel. Basically when the Mode of the PagerStyle is set to one of the values - Slider, Advanced, NextPrevAndNumeric, NextPrevNumericAndAdvanced - the Grid will not work as expected. That's why we are using NumericPages in the "Grid in XmlHttpPanel Demo".
