Hi Aravind,

I guess you are clearing the entire item in the RadComboBox on clear button click and you want to show "SELECT" as the EmptyMessage. Here is the complete code snippet I tried.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server"  EmptyMessage="SELECT">
   <Items>
        <telerik:RadComboBoxItem Text="Item1" />
            <telerik:RadComboBoxItem Text="Item2" />
            <telerik:RadComboBoxItem Text="Item3" />
   </Items>
</telerik:RadComboBox>
<telerik:RadButton Text="clear" ID="RadButton1" runat="server"
         OnClientClicked="OnClick1" AutoPostBack="false">
</telerik:RadButton>

JavaScript:

function OnClick1(sender, args)
{
        var combobox = $find('<%=RadComboBox1.ClientID %>');
        combobox.trackChanges();
        combobox.get_items().clear();
        combobox.clearSelection();
        combobox.commitChanges();
}

Please provide your code and elaborate the scenario it it doesn't help.

Thanks,
Shinu.
