Hi,

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:RadScriptManager>

<telerik:RadComboBox DataValueField="ID" EnableTextSelection="false"

Skin="Default" DataTextField="Name" ID="RadComboBox1" runat="server" >

<ItemTemplate>

<asp:CheckBox runat="server" ID="chk1"/>

<asp:Label runat="server" ID="Label1" AssociatedControlID="chk1" Text='<%# Eval("Name") %>'></asp:Label>

</ItemTemplate>

</telerik:RadComboBox>

</form>

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;

RadComboBox1.DataBind();

}

How can I achieve this?

thanks.

Leo
