DataTable.RowDeleting Event

Occurs before a row in the table is about to be deleted.

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

public event DataRowChangeEventHandler RowDeleting
/** @event */
public void add_RowDeleting (DataRowChangeEventHandler value)

/** @event */
public void remove_RowDeleting (DataRowChangeEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

For more information, see Working with DataTable Events.

private static void DataTableRowDeleting()
{
    DataTable customerTable = new DataTable("Customers");
    // add columns
    customerTable.Columns.Add( "id", typeof(int));
    customerTable.Columns.Add( "name", typeof(string));
    customerTable.Columns.Add( "address", typeof(string));

    // set PrimaryKey
    customerTable.Columns[ "id" ].Unique = true;
    customerTable.PrimaryKey = new DataColumn[] 
        { customerTable.Columns["id"] ;

    // add a RowDeleting event handler for the table.
    customerTable.RowDeleting += new DataRowChangeEventHandler( Row_Deleting );


    // add ten rows
    for( int id=1; id<=10; id++)
    {
        customerTable.Rows.Add( 
            new object[] { id, string.Format("customer{0", id), 
            string.Format("address{0", id) );
    

    customerTable.AcceptChanges();

    // Delete all the rows
    foreach( DataRow row in customerTable.Rows )
        row.Delete();


private static void Row_Deleting( object sender, 
    DataRowChangeEventArgs e )
{
    Console.WriteLine( "Row_Deleting Event: name={0; action={1", 
        e.Row["name"], e.Action );
