Combo Validation Issue - AllowCustomText

[Robert]

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>

Hello Robert,

Take a look at the following forum which implements a similar scenario.
Validate user input in RadCombobox with AllowCustomText="True" Filter="Contains"

Thanks,
