How to intercept gridview's Update event and alert user of required field if needed?
Posted on 2015-02-02
Hi, I'm using vs2012, C# and asp.net.
When a user updates a row, there could be 4 blank cells but when user checks a checkbox column then click Update, I would like to cancel the update and alert message to user that the 4 blank cells need to have text if they check that checkbox. I would only process the update if all 4 blank cells are no longer blanks.
