TemplateControl.AbortTransaction Event

Occurs when a user ends a transaction.

Namespace: System.Web.UI
Assembly: System.Web (in system.web.dll)
public event EventHandler AbortTransaction
/** @event */
public void add_AbortTransaction (EventHandler value)

/** @event */
public void remove_AbortTransaction (EventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

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 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");
}

void Page_Load(Object sender, System.EventArgs e)
{
    this.add_AbortTransaction(
        new System.EventHandler(Sub_AbortTransaction));
    this.add_CommitTransaction(
        new System.EventHandler(Sub_CommitTransaction));
    try {
        Account myAccount = new Account();
        int someAmount = 500;
        myAccount.Debit(someAmount);
        ContextUtil.SetComplete();
    }
    catch (System.Exception exp) {

        ContextUtil.SetAbort();
    }
} //Page_Load

private void Sub_AbortTransaction(Object sender, System.EventArgs e)
{
    // Code for RollBack activity goes here.
    get_Response().Write("Transaction Aborted");
} //Sub_AbortTransaction

private void Sub_CommitTransaction(Object sender, System.EventArgs e)
{
    // Code for Commit Activity goes here.
    get_Response().Write("Transaction Commited");
} //Sub_CommitTransaction
