LinqDataSource.Delete Method

Performs a delete operation.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

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.
