I have a form and at the bottom is the save link which I have renamed to "Submit Registration".

Well, I have users who think that links should be double-clicked like icons on a desktop and there form results get submitted twice, hence there are two email messages that get sent, and two sql calls. Unnecessary overhead and unnecessary extra email messages.

Is there anyway to have the "Save" link be disabled when it has already been clicked? You can then re-enable it if validation issues occur, or if mandatory fields are not filled in.

Thanks,

Hi. Well we are researching this down the road. ASP.NET 2.0 has a new feature that can be executed called on a link button (or other buttons) called "OnClientClick ". So you could technically do something that would disable the link button with that code set to disable the field. The bigger issue you are going to run into here though is possibly the form coming back (from the server side validation or something) could possibly be disabled even though the form wasn't submitted. For example, lets say you have a checkbox group field marked as required and server side validation turned on. The user might click Submit Registration, field would be disabled, then something might come back saying they have not submitted the proper fields. At this point the user is stuck on a page where they can't fix the submission. So... There are a few scenarios where this could cause problems. We are researching this though and should keep this thread open for more discussion for future versions (its not the first time its come up). For now though, you might want to add a note to the form or form footer such as 'Please click submit only once and do not refresh the browser...' etc...
