Hey, I'm relatively new to C# and ASP.NET, but have been doing OK.

I'm trying to understand why I can't do this kind of thing to execute a
function if and only if it's defined. Is there another way to do that?

try {
FormPostBack();
}
catch { }

Many thanks,

Rob

Because try..catch catches runtime errors. Calling undefined functions
results in a compile time error.

There are a couple things that come to mind, depending on what you want to
accomplish. The closest thing to what you are asking for is probably the
conditional attribute:

However, if your reasons for wanting this have to do with designing reusable
code, there's probably a beter way to do it, and you should take a close
look at the capabilities of virtual methods, delegates and events.
 
Thanks for the help. I'll see what I can find.
