Hi Rahul,

Please have a look into the following code snippet to achieve your scenario.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="true">
    <Items>
        <telerik:RadComboBoxItem Text="Item1" />
        <telerik:RadComboBoxItem Text="Item2" />
        <telerik:RadComboBoxItem Text="Item3" />
    </Items>
</telerik:RadComboBox>

JavaScript:

<script type="text/javascript">
    function pageLoad() {
        var combo = $find("<%=RadComboBox1.ClientID %>");
        combo.clearSelection();
        combo.set_emptyMessage("select");
    }
</script>

Let me know if you have any concern.
Thanks,
Shinu.
