Is there anything similar to "Error" event of System.Web.UI.Page of Webforms
in a Windows Forms?? I want to catch all errors occured in a windows form? I
already know there is Application.ThreadException but that is on application
level.

Hi Angelina,

No, there's nothing like that in Windows Forms, as far as I know. Actually,
you should think of such global handlers only as of a "safety net" that
prevents the whole app from a nasty crash if bad things happen.

My recommendation is to have exception handlers everywhere an exception can
occur. It's OK to have a reusable procedure responsible for displaying error
messages, but catch errors as close to the place they occur as possible.
With this strategy, you should be able to gracefully deal with many errors
without even having to display any message to the user.

Application.ThreadException

try placing a try-catch block where you instanciate you form, like:
try{
Form my = new Form();
my.Show();
......
}catch(Exception e){}

I use AppDomain.CurrentDomain.UnhandledException in the Program class,
even if a read an article about not all exceptions bee caugth with this
handler.
