DataRowChangeEventHandler Delegate

Represents the method that will handle the RowChanging, RowChanged, RowDeleting, and RowDeleted events of a DataTable.

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

public delegate void DataRowChangeEventHandler (
	Object sender,
	DataRowChangeEventArgs e
)
/** @delegate */
public delegate void DataRowChangeEventHandler (
	Object sender, 
	DataRowChangeEventArgs e
)
Not applicable.

Parameters

sender

The source of the event.

e

A DataRowChangeEventArgs that contains the event data.

When you create a DataRowChangeEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, until you remove the delegate. For more information about delegates, see Events and Delegates.

The following example adds a DataRowChangeEventHandler and the procedure to handle the event when a row is changed. The procedure prints the action and value of the changed row.

private DataTable dataTable;

private void AddHandler(){
   dataTable = new DataTable("dataTable");
   dataTable.RowChanged +=
      new System.Data.DataRowChangeEventHandler(dataTable_Changed);
}

private void dataTable_Changed(object sender,
System.Data.DataRowChangeEventArgs e) 
{ 
   Console.WriteLine("Row Changed", e.Action,
      e.Row[dataGrid1.CurrentCell.ColumnNumber]);
}
