I am having a problem validating a combo box using a custom validator but only when AllowCustomText = True. If I remove the AllowCustomText="True" property it will fire the validation. Any idea of what's going on here?? I have seen plenty of examples on the site using validation with Allowing custom text.
<telerik:RadComboBox ID="cboFromName" runat="server" Skin="Vista" AllowCustomText="True" MarkFirstMatch="True" Width="311px"> </telerik:RadComboBox> <asp:CustomValidator ID="CustomValidator1" runat="server" ClientValidationFunction="validateFromName"ControlToValidate="cboFromName" CssClass="body" ErrorMessage="From Name required"></asp:CustomValidator>
