I have a ComboBox set to Display None in code behind of page load of IsNotPostBack. When I click on another control, I am making this control visible from Jquery. I am using Set_visible(true) property. It works fine but When I submit the form for the server validation(post back) RadComboBox disappears. I am not setting this to none anywhere except in IsNotPostBack method. What could be the reason? Also How can I validate EmptyMessage with RequiredFieldValidator on the client side? Please let me know.
Thank you for any ideas..
