However, I would like to use client-side validation of asp.net Formviews and Gridviews, which are tables.  I have tried the existing examples, tweaking them in every way I could imagine, without any success.

Could the designers consider a spin-off that can be used to validate these types of tables?  Sure, I could reinvent the wheel and create my own functions, but I was hoping I could avoid reinventing the wheel.  They key is the "Insert" or "Update" buttons, which trigger the table functionality, and I have been unable to trigger the validation function on the clicking of those buttons instead of "submit" which triggers a form action.

Thanks
