TemplateControl.AbortTransaction イベント

定義

ユーザーがトランザクションを終了すると発生します。Occurs when a user ends a transaction.

public:
 event EventHandler ^ AbortTransaction;
public event EventHandler AbortTransaction;
member this.AbortTransaction : EventHandler 
Public Custom Event AbortTransaction As EventHandler 

次のコード例は、AbortTransaction イベントのカスタムイベントハンドラーを登録する方法を示しています。The following code example demonstrates how to register a custom event handler for the AbortTransaction event. TemplateControl は抽象クラスであるため、このコード例では、TemplateControl クラスから派生した Page クラスを使用します。Because TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account は、トランザクションであり、1つの単位として実行する必要がある、Debit 操作をサポートするクラスです。Account is a class that supports a Debit operation, which is transactional and must execute as a unit. この操作中に例外が発生した場合、トランザクションは終了します。If any exception is raised during this operation, the transaction is ended.


  private void Page_Load(object sender, System.EventArgs e)
  {
      AbortTransaction += new System.EventHandler(Sub_AbortTransaction);
   CommitTransaction += new System.EventHandler(Sub_CommitTransaction);
      try
   {
      Account myAccount = new Account();
      int someAmount = 500;
      myAccount.Debit(someAmount); 
      ContextUtil.SetComplete(); 
   }
   catch(Exception)
   {
      ContextUtil.SetAbort();
   }
  }

private void Sub_AbortTransaction(object sender,System.EventArgs e)
{
   // Code for RollBack activity goes here.
   Response.Write("Transaction Aborted");
}
private void Sub_CommitTransaction(object sender,System.EventArgs e)
{
   // Code for Commit Activity goes here.
   Response.Write("Transaction Commited");
}

   private Sub Page_Load(Sender As Object, e As EventArgs)

   AddHandler Me.myCommitTransaction,AddressOf Sub_CommitTransaction
   AddHandler Me.myAbortTransaction,AddressOf Sub_AbortTransaction

      try
   
      Dim myAccount As Account = New Account()
      Dim someAmount As Integer = 500
      myAccount.Debit(someAmount)
      ContextUtil.SetComplete()
   
   catch e1 As Exception
         ContextUtil.SetAbort()
   End Try
  End Sub

Public event myCommitTransaction As System.EventHandler 
 Public event myAbortTransaction As System.EventHandler
 
 protected overrides Sub  OnCommitTransaction(e As EventArgs )
  
       RaiseEvent myCommitTransaction(Me ,e)
       Response.Write("<br /><br />The 'OnCommitTransaction()' method is used to raise the 'CommitTransaction' event." )

End Sub
  
  protected  overrides Sub OnAbortTransaction(e As EventArgs)
       RaiseEvent myAbortTransaction(Me ,e)
       Response.Write("<br /><br />The 'OnAbortTransaction()' method is used to raise the 'AbortTransaction' event." )
  End Sub

private Sub Sub_AbortTransaction(Sender As Object, e As EventArgs)
  ' Code for RollBack activity goes here.
   Response.Write("Transaction Aborted")
End Sub

private Sub Sub_CommitTransaction(Sender As Object, e As EventArgs)
  ' Code for Commit Activity goes here.
   Response.Write("Transaction Commited")
End Sub
