Telerik RadGrid not displaying

Question

I have this radgrid that appears to be getting data but it is not displaying. After binding the grid.Items.Count is set to the number of rows expected.I'll includ the ajax manager settings and grid. One note if interested. In the onRequestStart javascript I'm just doing some client-side validation. Thanks!

Here's the appropiate snippets:

 <telerik:radajaxmanager id="RadAjaxManager1" runat="server"> 
         <clientevents onrequeststart="onRequestStart" />
        <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1">
                </telerik:AjaxUpdatedControl>
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="RadBtnRetrieve">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadPanelBar1" loadingpanelid="RadAjaxLoadingPanel1">

Here is an example from the telerik samples public partial class DefaultCS : System.Web.UI.Page { public void Page_Load(object sender, System.EventArgs e) { if (!IsPostBack) { LoadData(); }
}

        protected void RadGrid1_PageSizeChanged(object source, GridPageSizeChangedEventArgs e)
        {
            LoadData();
        }

        private void LoadData()
        {
            RadGrid1.DataSource = GetDataTable("SELECT CustomerID, CompanyName, ContactName, ContactTitle, Address, PostalCode FROM Customers");
        }

        protected void RadGrid1_PageIndexChanged(object source, Telerik.Web.UI.GridPageChangedEventArgs e)
        {
            LoadData();
        }

        protected void RadGrid1_SortCommand(object source, Telerik.Web.UI.GridSortCommandEventArgs e)
        {
            LoadData();
        }

        public DataTable GetDataTable(string query)
        {
            String ConnString = ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString;
            SqlConnection conn = new SqlConnection(ConnString);
            SqlDataAdapter adapter = new SqlDataAdapter();
            adapter.SelectCommand = new SqlCommand(query, conn);

            DataTable myDataTable = new DataTable();

            conn.Open();
            try
            {
                adapter.Fill(myDataTable);
            }
            finally
            {
                conn.Close();
            }

            return myDataTable;
        }
    }

Did you forget to put RadGrid1.DataBind?
