TemplateControl.AbortTransaction Event

Occurs when a user ends a transaction.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

'Declaration
Public Event AbortTransaction As EventHandler
<asp:TemplateControl OnAbortTransaction="EventHandler" />

The following code example demonstrates how to register a custom event handler for the AbortTransaction event. Because TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account is a class that supports a Debit operation, which is transactional and must execute as a unit. If any exception is raised during this operation, the transaction is ended.


   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
