Hello Abha,

The EmptyMessage is shown only when AllowCustomText property set to True. Set AlloCustomText to True and see whether it is showing. If you want, the user to not to allow typing in the textbox, then you can add the following client side code on page.

JavaScript:

<script type="text/javascript">
function pageLoad()
{
   var combo = $find("<%= RadComboBox1.ClientID %>");
   var input = combo.get_inputDomElement();
   input.onkeydown = onKeyDownHandler;
}
function onKeyDownHandler(e)
{
   if (!e)
       e = window.event;
   e.returnValue = false;
   if (e.preventDefault)
   {
       e.preventDefault();
   }
}
</script>
