I tried RegEx Validation control as you suggested and I kept getting this error below. I am using it inside <formview></formview> control don't know if this would cause error because when I use it inside <form></form> control seem to work fine. Thx.

if it is inside a formview then you need to do a findcontrol to get access to it.

In the ItemInserting event(you may have to use a different event) do something like:
Code:
Label mylabel = (Label)e.item.FindControl("lblOutput");
myLabel.Text = "Your Text Here";- Status
