Use the InsertNewItem method to programmatically insert an item in the data source. This method is typically used to insert an item from outside the ListView control, such as from a different control on the page.

To use the InsertNewItem method, you must define an InsertItemTemplate template in the ListView control. You must also set the InsertItemPosition property to a value different from InsertItemPosition.None. To specify whether page validation is performed before the insert operation, use the causesValidation parameter.

This method raises the ItemInserted and ItemInserting events.

The following example shows how to use the InsertNewItem method to programmatically insert the contents of the insert item of a ListView control into the data source.
