Datakeyvalue in ListView

[Ingo Oltmann]

Hi,

I am using the Datagrid as Listview as in this example:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/listview/defaultcs.aspx
I added a DataKeyField and created an ItemCommand eventhandler which fires fine using EnablePostbackOnRowClick. The problem is that I get the same DataKeyValue codebehind for each source record I click on. Can you show me a way out of this problem?

Regards,
Ingo

Can you post the solution to this on the forum for everyone else?  I'm interested in a workaround for this too.

Hi Adam,

The behavior you are observing is expected, since when using ItemTemplate only one dataitem is rendered on the client. Still there is a way to get the data key value for the item clicked. Here are the steps for this:

1. Attach a client event handler to the asp:Panel control for the ItemTemplate of the grid and pass to it the current item's index:

                    <asp:Panel ID="ItemContainer" ... onclick='<%#"sendID(" +((GridDataItem)Container).ItemIndex + ")" %>'>
                    ...
                    </asp:Panel>

2. Add an AjaxManager control to your page and attach an event handler to its AjaxRequest server event.

3. Go back to your aspx and add the client event handler for the panel click:

    <telerik:RadCodeBlock ID="Codeblock" runat="server">
    <script type="text/javascript">



        function sendID(index)
        {

           var manager = $find('<%=RadAjaxManager1.ClientID %>');

           manager.ajaxRequest(index);
        }


    </script>
    </telerik:RadCodeBlock>

4. Add the following code to the server-side event handler for the AjaxRequest event of the RadAjaxManager control:

        protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
        {
            string Id = RadGrid1.MasterTableView.DataKeyValues[4]["MediaID"].ToString();
        }
