Drag-and-drop ranking system...

[frosty7700]

I'm trying to created a system that allows a web user receive a list of items, drag-and-drop them into a new order, then submit them back to the server (via ASP). I know a drag-and-drop system can be implemented via JavaScript...but I only know how to do it in IE. Plus, I don't know how to go about passing the ASP this new data-order (the physical HTML form locations are unchanged code-wise so I don't see how I can use that).

So, I need to know 2 things:
-How can I pull this off in such a way that the data can be submitted back to a server-side ASP for re-ordering in the DB
-Less importantly, but if possible, how can I do this in such a way that is compatible with browsers other than IE?

I know it can be done. An example is at

the example you give uses a Java applet - it isnt done in ASP or Javascript Tony

OK. Now, could it be done with ASP and Javascript?

I'd prefer not to touch Java with a 10-foot pole.

To be honest, I think it's going to be horrendously difficult, if actually possible, to do this using javascript.

You might find more help in the javascript forum - forum216. Good luck! --James

Well i don't know if Netscape (or what versions) support drag and drop, but generally you cannot count on browser compatibility EVER!

What the heck does that mean?

That should be simple if you can already do the drag and drop as you say (in IE).

It's in an internal, controlled environment. So the end-users will use whatever they're given.

You'd think.
It's weird stuff.

Well, theres always MS DDRK Drag and drop built in, it's not my choice for intranet development, but it already handles what your looking to do with the added bonus of being able to setup user accounts so they have a sort of limited control how the interface looks when they log in.

It was poorly worded, to say the least. I couldn't figure a way to make my JavaScript code modify the values contained in the form elements of the rows I'm dragging. The means of pulling off the drag-and-drop don't seem to cater to this possibility. Irrelevant now, regardless. I'm pretty sure I'm gonna dump JavaScript as a means of doing this now anyways. Seems a bit like using toothpicks and paste to build a car.
