The default button on enter on an ASP.NET form
I haven't really thought about this in a long time, but after searching a bit and finding some really complex solutions, I figured out a way to fire a "click" based on pressing enter in a text field. It works OK in IE and Firefox, which is good enough for me, and it only requires one line.
I can't understand why this wasn't included somewhere in v2. They did offer a default button for the entire form, but I think that only works if you have actual buttons (I use LinkButtons almost exclusively). You could actually wire up any control name here if you wanted.
