Hi David,

In order to achieve your scenario try to use the asp RequiredFieldValidator control.

ASPX:
<telerik:RadTextBox ID="rtxtValue" runat="server">
</telerik:RadTextBox>
<asp:RequiredFieldValidator ID="valtxtValue" ControlToValidate="rtxtValue" runat="server"
    ErrorMessage="required">
</asp:RequiredFieldValidator>
<telerik:RadButton ID="rbtnsave" runat="server" Text="submit" AutoPostBack="false">
</telerik:RadButton>

Thanks,
Princy.
