public partial class sqldsTransaction:System.Web.UI.Page
{
protected void Page_Load(object sender,EventArgs e)
{
}
protected void btInsert_Click(object sender,EventArgs e)
{
   sqldsEmplyees.Insert();
}
protected void sqldsEmployees_Inserting(object sender,SqlDataSourceCommandEventArgs e)
{
   Dbcommand cmd=e.command;
   Dbconnection conn=cmd.Connection;
   conn.Open();
   DbTransaction tran=conn.BeginTransaction();
   cmd.Transaction=tran;
}
protected void sqldsEmployees_Inserted(object sender,SqlDataSourceCommandEventArgs e)
{
   if(null==e.Exception)
   {
    e.Command.Transaction.Commit();
    showMsg("Insert Ok,Transaction Ok!");
   }
   else
