RadGrid for ASP.NET AJAX and GridButtonColumn

[Bob]

I have a RadGrid in a DNN module which the first column is a GridButtonColumn called Report.  If the user clicks Report button a Crystal Report is displayed on seperate window not within DNN.  The user can view print or export the report.

Well this worked fine until I finally got AJAX working in DNN.  I was registering a startup script after capturing in a session variable the row clicked identified.  In the RadGrid ItemCommand event I identified it was the button pressed which still works but now I can not because of AJAX register a script to run.  I tried just adding a function on the User Control but have not figured out how I can call this function from the ItemCommand event.  I read how to do Callbacks and they act like I need...the client passes back to the server information on what was requested and them the callback fires back a function on the client with passed arguments. 

It would be nice if I could make RadGrid fire a function OnClicked for GridButtonColumn but have found no way of redirecting the event to a client function.  The javascript on the client is:

<script type="text/javascript">
    function OpenReport(arg, context)
    {
         window.open(arg, "_blank","width=700, height=500, scrollbars=yes, menubar=no, resizable=1");
    }
</script>

and the partial code behind for RadGrid ItemCommand is:

If e.CommandName = "Report" Then
    Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
    If dataItem("Rev").Text <> "1" Then
        Dim pagePath As String = Me.ResolveUrl("Report.aspx")
        Session("rptID") = dataItem("ID").Text
        Session("rptRev") = dataItem("Rev").Text

        ????????? DO NOT KNOW HOW TO CALL FUNCTION OpenReport ???????

    End If
End If

Can you please lead me in the right direction?

Hi Bob,

Try the following code snippet.


ASPX:

<telerik:GridButtonColumn HeaderText="Click" Text="Click" UniqueName="Click">
                    </telerik:GridButtonColumn>

CS:

 protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            item["Click"].Attributes.Add("OnClick", "return OpenReport();");

        }

    }

JS:

     <script type="text/javascript" language="javascript">
      function OpenReport()
       {

       }

   </script>

Thanks
Princy.

I have some reformating to do but that will definitely work.  Can I do this on the ItemCreated event?

Item["Click"]Attributes("Onclick") = [String].Format("return ShowForm('{0}','{1}','{2}');", e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("ID"), e.Item.ItemIndex, pagePath)

Hi Bob,

Have a look at the following KB article.
