The following code example demonstrates how to use the Details View Update Event Args object passed to the event handler for the Item Updating event to validate the values entered by the user.
The problem is that during Item Updating event of Form View, New Values table is empty. Form View1 talks to my Opportunity table and has an Item Template and an Edit Item Template.To determine the value of the command argument, use the Command Argument property.To cancel the update operation, set the Cancel property to . The page has, among other things, two Form Views and a Grid View control, each with its own Sql Data Source. Net 2.0 framework, and I have a serious problem with the page I'm currently working on.As far as I can tell, the problem is that the program is not passing updated information to the New Values array that you can access from the Item Updating event args. The code and markup looks fine to me, in fact I have a page with similar information on it that works fine. That Form View is nearly identical to one on the page that doesn't work; in fact, I copied and pasted the markup to keep the formatting correct.
