Managing the order of multiple Events link to a single Event Handler

[Sylvain]

Hi All

I need to add a new event at the beginning of an event handler
e.g.: I've got a textbox which is assigned an event at design time to the TextChanged eventhandler, but I need to add a new event to it from an other class during run time, and this new event has to be called BEFORE the event assigned at design time. (i.e. I cannot use +=..
I could not find any information on this in the MSDN help, so any Idea please
Thank you for your time

1. Maybe there is another, more appropriate event for you to hook, other
than text changed (Validate?, Validating?)

2. You could always create a new event. You would create a derivitive of
the textbox:

public class MyTextBox: TextBox
{
event System.EventHandler MyTextChangeEvent;
override protected void OnTextChanged(System.EventArgs e)
{
// fire your custom event
// guaranteed to fire first
if(this.MyTextChangeEvent != null)
this.MyTextChangeEvent(this, e);
// call base so that the TextChangedEvent is fired
base.OnTextChanged(e);
}
}
