Creating a drag and drop enabled web application

[casicadk]

Hi

I need to accomplish the following, in order for a customer (company
of sportphotograpers) to quickly an intuitively sort his images in
categories:

- Display some thumbnails of images
- Display some folders
- User must be able to drag images to the folders (like basic
fileoperations in windows)
- Must run on modern MAC's in a webbrowser

I am completely blank here, have never done web-based drag and drop
before.

Whether I use silverlight, ajax, some commercial component or whatever
does not matter, as long as it fits the above requirements.

I am not looking for a complete solution here, just pointers to what I
should use and where to start.

Best regards
Klaus

Drag and drop is client-side code and has very little to next to nothing to
do with asp.net. Its been a few years now before AJAX but I've seen some
impressive d&d JavaScript libraries you'll be able to find if you can also
figure out how to find them using Google. Good luck to ya though, your to-do
list looks quite demanding.

Oh yea, I would also review and evaluate the Yahoo User Interface Library
(YUI). I use their CSS and their code is high quality stuff and probably
another reason why Microsoft really wanted to acquire Yahoo compared to the
incomplete buggy and orphaned mess that we have come to know and love as the
2.0 controls.

YES WAY

There's no way to master classic web development without mastering
JavaScript as its one of the required five web development fundamentals:

1.) HTML (client-side UI)
2.) CSS (client-side UI)
3.) JavaScript (client-side code)
4.) C# (server-side code)
5.) T-SQL (server-side database)

On the other hand there's another web development model; developing a file
containing bytecode that is parsed by a run-time executable...

* Flash
* Silverlight

And both Flash and Silverlight still require a mastery of JavaScript more so
with Flash as it uses proprietary make-believe JavaScript which is called
ActionScript.

This doesn't even take into account all of the other query and
transformation grammars like XQuery, XPath, XSL and so on. Perpetually
incompetent
