    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:
    Accessing cells and rows

    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:
