I am writing a item insert validation in "ItemAdding Event" of event handelr. After validating the page is redirecting to the error page showing the custom error message.
My requirement is ...
Instead of moving to the error page the custom error should display in a pop-up dialog box on the same page. If I will click on the ok than the page should not redirect to any where(the focus should be in the same page) and the value in the field
should not reset.
Please help me..
