ASP: How to preserve html form field values?

[SONYFX]

In the link below if you type anything in the textbox and click "refresh" button on browser, the value will be gone, is there any way to preserve it? Thanks!

Just dump the value into a session variable.

There's no way you can influence that from the server side, at least for a simple refresh. Firefox keeps the form values when you do a refresh, though. It seems rather stupid for a browser to erase the values Unless, can you capture a refresh even in javascript?...

If the user actually submits the data then you can do as mooby suggested and record the value entered somewhere and put it into the form the next time it's requested.

Use AJAX to asynchronously post the data to the server?

I used that on one of my web apps - users could enter a very long free text response - this provided an autosave feature in compatible browsers (not opera).

Ooh, very nice How often did you save? On a timer, or onblur of the text boxes?

Every minute, or every 100 keypresses on the text box (which ever comes first). This was fine for a very lightly loaded intranet site, but may need tweaking for a public site.

Can you give me an example? Thanks!

I can't show you a demo site because the app was written for internal institutional use, and is not publicly available.

I also don't have a publicly accessible server running ASP.NET so couldn't just set you up a demo. Sorry.

May I ask why you want to do this? Just want to make sure you are thinking clearly. If you make it keep the user's values, you need to also have a reset button to clear the values. Plus if this is a site where users won't come often, it's going to confuse them.
