Select Row and Enter in a Server Side Code

[lupotana]

Hi, I've a small problem with RadGrid.
I must transform old code with ASP.NET GridView in a new code with Telerik RadGrid.

In old version I've two TemplateField in my GridView : in first column  there is a label with the code of row (hide) and in the second column there is an ImageButton with an Handler with the function btnUpdate_Click.

....

<asp:TemplateField Visible="false">
 <ItemTemplate>
         <asp:Label ID="lblCode" runat="server" Text='<%# Bind("Code") %>' />
        </ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
 <ItemTemplate>
         <asp:ImageButton ID="btnEdit" runat="server"  ImageUrl="~/edit.png" OnClick="btnEdit_Click" CausesValidation="false" />
 </ItemTemplate>
</asp:TemplateField>

......

In function btnEdit_Click I cast the row and the Label control in the row and with the code I transfer the page.

protected void btnEdit_Click(object sender, EventArgs e)
{
 GridViewRow row = ((GridViewRow)((ImageButton)sender).NamingContainer);
 Label lblCode = (Label)row.Cells[0].Controls[1];
 Server.Transfer("~/Detail.aspx?Code="+lblCode.Text);
}

How do I do this operation with RadGrid?
I don't want use the the Inline solution or client scripts.
I need that when the user click on an imageButton or button in a row I enter in a server side code.

Thanks,
Marco

Hello Marco,

You can try out the following code to access the label in a TemplateColumn on clicking a button inside another TemplateColumn:
c#:

 protected void btnEdit_Click(object sender, ImageClickEventArgs e)
    {
        GridDataItem row = ((GridDataItem)((ImageButton)sender).NamingContainer);
        Label lblCode = (Label)row.FindControl("lblCode");
        Server.Transfer("~/Detail.aspx?Code=" + lblCode.Text);
    }

Also go through the following help document which you may find helpful:

Thanks
Princy.

My problem is not the server code... the problem is that in RadGrid don't have a Template Column.
How I manage an event click in an imagebutton in the row ?

For example : a Row have an image for the update and an image for the delete.
I don't want use the example of telerik..
I want that after click the imagebutton I enter in a server code with the index row slected.

Is possible ?

Hi lupotana,

RadGrid does have a template column and it is called GridTemplateColumn:

In addition, the solution Princy has offered is the valid one in your case.

Hi, with new versions of Telerik I able to do this operation.
Now my question is : Server.Transfer work if I not use RadGrid with RadAjaxManager. Is not possible use Ajax with Server.Transfer ?

protected void gvList_SelectedIndexChanged(object sender, EventArgs e)
 {
 GridItem row = gvList.SelectedItems[0];
 HttpContext.Current.Items.Add("Operation", EventContext.Update.ToString());
 HttpContext.Current.Items.Add("CustomerCode", row.Cells[2].Text);
 Server.Transfer("~/Desktop/Function/Customer/CustomerDetail.aspx");
}

Hello Marco,

Basic server transfer couldn't be achieved during Ajax request. I would suggest you to revise the discussion below for more information on possible alternative approaches:
