Drag & Drop User Controls in ASP.NET

[mfozmen]

First of all i wanted to say hello to Daniweb community because this is my first thread here.

I need to design a web site that clients can easily drag & drop pre-defined user controls and create a simple web site for themselves. Users will also upload their data to these controls and the data will be stored in database or cache. Something like "igoogle" but more simple. Where should I start for this project? Which components may help me? Also, is it so hard or can I make this easily?

Thanks for your help

Look into jquery, page methods and ajax(probably using jQuery).

There are ASP.Net server controls called WebParts that might be able to help as well.

Thank you stbuchok. I researced and already decided to use webparts. I never used them but i try to understand now but seems not so hard.
