    Hello,
    I'm writing a custom control and got problem with a null value for the RadGridView (and also others controls)
    Here's my ascx :

    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="SearchPage.ascx.cs"
        Inherits="SitefinityWebApp.SearchPage" %>
    <%@ Register TagPrefix="telerik" Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" %>
    <%@ Register TagPrefix="sitefinity" Namespace="Telerik.Sitefinity.Web.UI" Assembly="Telerik.Sitefinity" %>
    <%@ Register TagPrefix="sf" Namespace="Telerik.Sitefinity.Web.UI.PublicControls.BrowseAndEdit"
        Assembly="Telerik.Sitefinity" %>
    <div id="itemsContainer" runat="server">
    <asp:Label runat="server" Text="prova" ID="jason"></asp:Label>
        <telerik:RadGrid runat="server" ID="gvResult" AutoGenerateColumns="false">
            <MasterTableView>
                <Columns>
                    <telerik:GridBoundColumn UniqueName="FileName" DataField="Title">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn UniqueName="DateCreated" DataField="DateCreated">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn UniqueName="FileName" DataField="Title">
                    </telerik:GridBoundColumn>
                </Columns>
            </MasterTableView>
        </telerik:RadGrid>
    </div>

    and here's the cs:

    public partial class SearchPage : System.Web.UI.UserControl
       {
           private string queryString = string.Empty;
           private bool searchTagOnly = false;
     
           protected void Page_Load(object sender, EventArgs e)
           {
               if (Request.Params["query"] != null)
               {
                   queryString = Request.Params["query"];
               }
     
               if (Request.Params["tag"] != null)
               {
                   searchTagOnly = Convert.ToBoolean(Request.Params["tag"]);
               }
     
     
               PerformSearch();
           }


    when I do

    gvResult.DataSource = result; <- gvResult is null and also this.Controls has 0 items...
    gvResult.DataBind();

    Why this happen?
    Thanks

    Hello Paolo,

    Thanks for the code, but it doesn't show where you create and set value of the "result" . Can you show how you set this value?

    Best wishes,
