Adding event handlers via Attributes isn't absolutely necessary with a Button; it would be with a checkbox or a radio button, which don't have an onclick in ASP.NET, so you'd receive an annoying warning. With a button, you just need to write

Expand|Select|Wrap|Line Numbers

onclick="checkDate();"

in the asp tag, and that's it.

I'm glad you got it working.
For more information and examples on how to use JavaScript in .NET, you should check out the .NET Article on How to check if a textbox contains a number.

Cheers!
