public int Delete(
	IDictionary keys,
	IDictionary oldValues
)

Parameters

keys
Type: System.Collections.IDictionary

The row key values for the records to be deleted.

oldValues
Type: System.Collections.IDictionary

The row values that are evaluated to detect data conflicts.

Return Value

Type: System.Int32

The number of records affected by the delete operation.

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.
