Hello everyone,

I would like to know if it's possible to add a CustomValidator with a ValidatorCalloutExtender  into a WebCombo

I have a property in my CustomValidator called : ControlToValidate

When I write the ID of a asp.net control like a TextBox everything is OK.

But when I write the ID of my WebCombo, I got a  System.Web.HttpException

Here is the code :

<asp:CustomValidator

ID="CV"

runat="server"

ErrorMessage="Error"

ClientValidationFunction="cboLangueValidate"

ControlToValidate="cboLangue"

/>

<cc1:ValidatorCalloutExtender

ID="ValidatorCalloutExtender2"

runat="server"

Enabled="True"

TargetControlID="CV"

/>

Can anyone give me an advice.

Thanks in advance
