Remarks
The ItemCreated event is raised after all rows are created in a FormView control. This can occur when the control is first rendered, or when the user navigates to another record. You can use this event to provide an event-handling method that performs a custom routine, such as adding to or modifying the contents of a row, whenever this event occurs.
Note
The ItemCreated event occurs before the FormView control is bound to data. To modify the value of a bound field, use the DataBound event.
You can access the header, footer, and pager rows in the FormView control by using the HeaderRow, FooterRow, TopPagerRow, or BottomPagerRow properties, respectively. To access the data row, use the Row property.
For more information about how to handle events, see Handling and Raising Events.
