Thanks for any other solutions...

Answer 1

Specifically to answer your question as stated in your title: to add additional event handlers to an asp:button or other server controls that are not composite you simply add the handler to the element. Include onmousedown="myMouseDownHandler(this);" in the element and the javascript function myMouseDownHandler will fire.

However, I think there is a better way to do what your asking but the description of the question is not coherent enough for me to quite figure out what you're asking. I realize you may not be a native English speaker but perhaps you could give it another pass.

Answer 2

Use ValidationGroup property on controls that are validated and controls that triggers validation (e.g. save/update buttons) and on validators.
Additionally set CausesValidation property to false on each button that does not need to trigger validation (cancel button).
