Updating an entry of table using mygeneration tool

To change an entry of the table is also interesting and easy. You don't need to write an update query or even think of creating and closing a sql connection...even no chance to hurt a primary key also. Just follow these steps. Lets consider the Admin table. Suppose Admin wants to change the password having AdminID=5. So here lies the following code:

try
{
Admin admin=new Admin();
admin.ConnectionString=ConfigurationManager.ConnectionStrings["MASUDDBConnectionString"].
ConnectionString;
if(admin.LoadByPrimaryKey(5))
{
admin.AdminPassword="new password";
admin.Save();
/*entry updated successfully*/
}


}
catch(Exception exc)
{
/*error notification*/
}

So this is the easiest way to update a table entry as I believe. what do you think about this?
