protected virtual void OnCommitTransaction (EventArgs e);
abstract member OnCommitTransaction : EventArgs -> unit
override this.OnCommitTransaction : EventArgs -> unit
Protected Overridable Sub OnCommitTransaction (e As EventArgs)
Parameters
Examples
The following code example demonstrates how to use the OnAbortTransaction and OnCommitTransaction methods. 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 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
Remarks
You can use the OnCommitTransaction method for any transaction processing logic in which your page or user control participates.
