Remarks
Typically, you do not have to call the Delete method from your code. When you use a LinqDataSource control with a data-bound control, the data-bound control will automatically call the Delete method when the user takes action to delete a record. You explicitly call the Delete method when you want to create your own process for deleting data. For example, you can call the Delete method when you want to delete a record based on an event outside the data-bound control.
