    How can I set an Empty Text when the RadCombo is loaded?

    In the attached code, after the binding, The item "Mark" is automatically highlighted (but not selected, as I want).
    My goal is to have, after the binding, no selected elements and an empty Text in the combobox.
    The dropdown has to stay "read-only" (user cannot input text)

    <form id="form1" runat="server">
    <telerik:RadScriptManager runat="server">
    <telerik:RadComboBox DataValueField="ID" EnableTextSelection="false"
        Skin="Default" DataTextField="Name" ID="RadComboBox1" runat="server" >
        <asp:CheckBox runat="server" ID="chk1"/>
        <asp:Label runat="server" ID="Label1" AssociatedControlID="chk1" Text='<%# Eval("Name") %>'></asp:Label>
    using System;
    using System.Web;
    using System.Web.UI;
    using System.Web.UI.WebControls;
    using System.Data;
    using System.Configuration;
    using System.Web.Security;
    using System.Web.UI.WebControls.WebParts;
    using System.Web.UI.HtmlControls;
    using Telerik.Web.UI;
    using System.Web.UI.MobileControls;
    using RadControlsWebApp1;
    using System.Collections.Generic;
    public partial class Default : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)
            List<Item> items = new List<Item>();
            items.Add(new Item() { Id = 1, Name = "Mark" });
            items.Add(new Item() { Id = 2, Name = "Jon" });
            items.Add(new Item() { Id = 3, Name = "Frank" });
            //RadGrid1.DataSource = items;
            if (!IsPostBack)
                RadComboBox1.DataSource = items;

    How can I achieve this?
