To perform one of these operations, set the Command Name property of a button to one of the values in the following table. Set the Command Argument property of the button to "First", "Last", "Next", "Prev", or a page number to specify the type of paging operation to perform.
Raises the Page Index Changed and Page Index Changing events.
This is basically saying that if we've set a Select Method, an Update Method, or a Delete Method (these are string properties on the Form View) then return true, otherwise tell us if we've set an Insert Method.
I was stocked for sometime using the 2.0 Details View control to Edit/Update data.
Do I need something additional to fire Item Updated?
I wanted to do my custom implementation for the Update command instead of using the Data Binding Object sources but I found my self in trouble with several road blocks.
Problem 1: When clicking on the Edit button the Details View will not change the mode until the second click.
A Form View Insert Event Args object is passed to the event-handling method, which allows you to determine the value of an optional command argument sent to the Form View control and to indicate that the insert operation should be canceled.
The command argument value corresponds to the Command Argument property of the Insert button.
