How to give different empty message for different search option in RadSearchBox?

[jackson]

 I have a telerik:RadSearchBox in which,there are three option for searching .For different option the empty message must be different.
For example 1)For Tag / Serial: “Search Tag or Serial Number.” 2)For Staff: “Search Staff ID or Name” 3)For Students: “Search Student ID or Name.”

<telerik:RadSearchBox RenderMode="Lightweight"   runat="server" ID="RadSearchBox1" Width="250" DropDownSettings-Height="100" MaxResultCount="20">
<SearchContext ShowDefaultItem="false">
<Items>
<telerik:SearchContextItem Text="Tag / Serial" Key="Tag" />
<telerik:SearchContextItem Text="Staff" Key ="Staff" />
<telerik:SearchContextItem Text="Student" Key ="Student" />
</Items>
</SearchContext>
</telerik:RadSearchBox>
