I have a AdvandeForm with a radComboBox
<li class="rfbRow">
<asp:Label runat="server" Text="Empleado" CssClass="rfbLabel" />
<telerik:RadComboBox runat="server" ID="RadUser" Type="User" Filter="Contains" />
</li>
And i want to fill this combo on the Default.aspx.vb and not on the AdvanceForm.ascx.vb.
How can I get the radComboBox and fill it?
