Fail operation of Drag To Group, Filtering, go to Second page of Grid

[Karen]

I have remove the below Script:

<%@ Register TagPrefix="telerik" Namespace="Telerik.QuickStart" %>
<%@ Register TagPrefix="telerik" TagName="Header" Src="~/Common/Header.ascx" %>
<%@ Register TagPrefix="telerik" TagName="HeadTag" Src="~/Common/HeadTag.ascx" %>
<%@ Register TagPrefix="telerik" TagName="Footer" Src="~/Common/Footer.ascx" %>
<%@ Register TagPrefix="sds" Namespace="Telerik.Web.SessionDS" %>

then, when I added these functions (as title), it has an error at the run time. the error occur when I do the action both Drag To Group, Filtering, go to Second page of Grid. it said:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

But, it is work if I select row, resize the column width and my other function in my web, so I can confirm that is only error occur when Drag To Group, Filtering, go to Second page of Grid.

Hello Karen,

Could you confirm if what is described in the error message does not apply to your code - having Response.Write(), response filters, etc. in your source? Also, do you have any custom code in your ItemCommand event handler? If you are running source code that is similar to a demo of ours, could you please let us know which demo exactly it is and what are the differences between your code and ours?

Sincerely yours,
