[CLOSED] itemdblclick event redirect request failure

[redi]

I have a grid with row expander, the row expander has before expand direct events, calling a function on code behind.

The expanded grid also has itemdblclick and itemclick direct events. itemdblclick calls redirect function from code behind.

When I double-click on the row to activate the itemdblclick event, there's an error communication failure pop up, but the pop up will close immediately and redirect the page (as what the event should be doing).

So it pop up error, but there's no actual error happens. Is there something I am doing wrong? Please help me with this. Thanks.

Here's my aspx code

Hi @redi,

Please demonstrate how you do redirection. In other words, please show the CellDblClickHandler server method.

This is how I do it,

  Public Sub CellDblClickHandler(ByVal sender As Object, ByVal e As DirectEventArgs)
        If X.IsAjaxRequest Then
           
            Dim TextDocNo As String = e.ExtraParams("filename")

                    Dim iUserID As String = Me.Session("UserID")
                    TextDocNo = TextDocNo.Replace("&", ";amp")

                    Dim url As String
                url = "frmISO_DocFileList.aspx?FileName=" & TextDocNo & "&UserID=" & iUserID

                ExtNet.Redirect(url)

                    Exit Sub

        End If
    End Sub

Hmm, it should be OK. I mean that I don't quite understand why you see a request failure.

Please provide a standalone, runnable test case to reproduce the problem.
