How do you make AutoGenerateEditButton inside of asp:DetailsView a button instead of a link? Right now it is a link and the text is "Update". I would want that to be a button saying "Update".
Please take a look at this:

Another option is to avoid the DetailsView and create the form manually. Example:

Scheduler: http://code.daypilot.org/75958/scheduler-and-modalpopupextender-asp-net-c-vb-net
