After updating dll update, adding script files and everything, still there found to be some problems.

I have some  pages in my project that use sendcustomrequest of webgrid. And does some calculations in the server initialise postback event. After that a response.redirect(or server.transform) is made based on the calculations. After updating to Webgrid 7, the redirection is not working. It doesnt throw any error. In fact i put a breakpoint in the second page and found that the control is actually transferring to the second page and it runs as well. However its not getting live. So if i perform any further operation on the first page again, the operation is done on the context of the first page itself. In fact it should have shown error if the context is switched to the first page. '

Protected Sub WGAccountCategory_InitializePostBack(ByVal sender As Object, ByVal e As ISNet.WebUI.WebGrid.PostbackEventArgs) Handles 		WGAccountCategory.InitializePostBack
        If e.Action = PostBackAction.Custom Then
            If (hfDelActive.Value = "Delete") Then
                ChangeStatWebGrid(hfDelId.Value, "Y")
                WGAccountCategory.ClientAction.Refresh()
            Else
                ChangeStatWebGrid(hfDelActive.Value, "N")
                Response.Redirect("EditAccountCategory.aspx?ACId=" + hfDelActive.Value, True)
                'HttpContext.Current.ApplicationInstance.CompleteRequest()
            End If
        End If
End Sub

In short after updating, calling response.redirect or server.transfer in the initialise postback event doesnt switches the context to the second page. Suppose i put an alert just after the grid.sendCustomRequest() event in javascript, the response.redirect works and switches to the second page. Voila!. So i suppose the javscripts causing some error. The error is critical for our project. so pls respond immediately.
