Hello,
I want to use a CustomValidator for a RadTextBox. The RadTextbox is inside an asp:Panel which is ajaxified with the RadAjaxManager. I have a CustomValidator with a ClientValidationFunction and ValidateEmptyText="True". However, the client side validation function is never called.
Below is the code extract from the control and validator. Note that the RequiredFieldValidator (again inside the Panel) works fine. Note that I am using Q3 2013
