Solution

  • You could set InitialValue = "Search..."

    <asp:RequiredFieldValidator ID="rfvSearch" runat="server" 
    ControlToValidate="Search" ErrorMessage="please insert text" 
    ValidationGroup="Search" SetFocusOnError="True" Display="None"
    InitialValue="Search...">
</asp:RequiredFieldValidator>

    Doing this, error message will be shown unless Search contains something different to Search...
