Occurs when a user ends a transaction.
Assembly: System.Web (in System.Web.dll)
The following code example demonstrates how to register a custom event handler for the 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
