Update Message on ASP.NET ModelPopupExtender
- by John
Hi,
I have a form in a MS AJAX ModalPopup Extender, which is in a UpdatePanel (for async loading). Everything works as expected. There is one thing that I am trying to do but not sure how to do it.
On form submission, there is server side validation on top of client side validation. My question is: what is the best way to display validation error…
