TemplateControl.CommitTransaction Event
.NET Framework 2.0
Occurs when a transaction completes.
Namespace: System.Web.UI
Assembly: System.Web (in system.web.dll)
Assembly: System.Web (in system.web.dll)
The following code example demonstrates how to register a custom event handler for the CommitTransaction 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
