DesignerTransactionCloseEventHandler Delegate
Assembly: System (in system.dll)
[ComVisibleAttribute(true)] public delegate void DesignerTransactionCloseEventHandler ( Object sender, DesignerTransactionCloseEventArgs e )
/** @delegate */ /** @attribute ComVisibleAttribute(true) */ public delegate void DesignerTransactionCloseEventHandler ( Object sender, DesignerTransactionCloseEventArgs e )
Not applicable.
Parameters
- sender
The source of the event.
- e
A DesignerTransactionCloseEventArgs that contains the event data.
When you create a DesignerTransactionCloseEventHandler 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, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.

The following example demonstrates registering a DesignerTransactionCloseEventHandler and handling the TransactionClosing and TransactionClosed events.
public void LinkDesignerTransactionCloseEvent(IDesignerHost host) { // Registers an event handler for the designer TransactionClosing and TransactionClosed events. host.TransactionClosing += new DesignerTransactionCloseEventHandler(this.OnTransactionClose); host.TransactionClosed += new DesignerTransactionCloseEventHandler(this.OnTransactionClose); } private void OnTransactionClose(object sender, DesignerTransactionCloseEventArgs e) { // Displays transaction close information on the console. if( e.TransactionCommitted ) Console.WriteLine("Transaction has been committed."); else Console.WriteLine("Transaction has not yet been committed."); }
public void LinkDesignerTransactionCloseEvent(IDesignerHost host)
{
// Registers an event handler for the designer TransactionClosing and
// TransactionClosed events.
host.add_TransactionClosing(new DesignerTransactionCloseEventHandler(
this.OnTransactionClose));
host.add_TransactionClosed(new DesignerTransactionCloseEventHandler(
this.OnTransactionClose));
} //LinkDesignerTransactionCloseEvent
private void OnTransactionClose(Object sender,
DesignerTransactionCloseEventArgs e)
{
// Displays transaction close information on the console.
if (e.get_TransactionCommitted()) {
Console.WriteLine("Transaction has been committed.");
}
else {
Console.WriteLine("Transaction has not yet been committed.");
}
} //OnTransactionClose
