Fact of the matter is, if you put a whole bunch of buttons on your form, then you're going to need a whole bunch of handlers. The benefit of tying all buttons to a single handler is that much less code needs to be written, making your program leaner and more efficient.

But whining about the correct solution because you may have to do a little typing is just childish and pointless. In the time it took you to post complaints, you could have finished adding the required code and done something useful.
