Namespace:   System.Data
Assembly:  System.Data (in System.Data.dll)

property IDbCommand^ DeleteCommand {
	IDbCommand^ get();
	void set(IDbCommand^ value);

Property Value

Type: System.Data::IDbCommand^

An IDbCommand used during Update to delete records in the data source for deleted rows in the data set.

During Update, if this property is not set and primary key information is present in the DataSet, the DeleteCommand can be generated automatically if you set the SelectCommand property of a .NET Framework data provider. Then, any additional commands that you do not set are generated by the CommandBuilder. This generation logic requires key column information to be present in the DataSet. For more information see Generating Commands with CommandBuilders.

When DeleteCommand is assigned to a previously created IDbCommand, the IDbCommand is not cloned. The DeleteCommand maintains a reference to the previously created IDbCommand object.

The following example creates an instance of the inherited OleDbDataAdapter class, and sets the SelectCommand and DeleteCommand properties. It assumes you have already created an OleDbConnection object.
