It would be of tremendous advantage to know what exactly you are trying to achieve.
There are problably more variations of "web frontends" than there are grains in the Sahara desert.

More information on what you want and what you've tried would help. However, you may want to look at Wijmo. Great products with good support.

We are trying to build web internal application for about few hundred users and I am designing the front end with good visual design (my background is developer)
I search online, I think I want the web looks like here with middle main menu (http://www.raswa.org.au/) with some smooth movement component for the left navigation menu... (eg. componentArt).

Hence I hope there is some tools or component that I can use with coding it from the scratch (in the past when I use php, I was designing the front end using dreamweaver)

Thanks guys,

Here's your first web design tip: There are web sites and web applications. They should have different designs as they serve different purposes.

When it comes to web, you need to throw everything out the door that you know about desktop apps. You're tied to what you can accomplish with HTML, CSS, and javascript. Learn those. Learn some additional tools like jQuery that make javascript easier. Learn jQueryUI that gives you some additional UI widgets.

Look at ASP.Net MVC. It's easy to use and fully supports HTML5 and CSS3.

Since you've mentioned ComponentArt and are posting in the C# forum, you might want to take a look at DotNetNuke or simply at Microsoft WebMatrix together with Visual Studio or simply VS on its own.
If you say "internal web application", are you talking about an intranet? "Translating" certain tools/scripts onto an internal web platform?

internal web application, yes... it was originally plan and our overseas employees need to be able to access that as well.

I have done front end coding like HTML, CSS, javascript but I just dont wanna code it from the scratch as it would take too long and not effecient since I'm pretty sure there would be so many tools that can help us now.
from the business and data layer I'm gonna use C# and code generator to connect to database.

JQueryUI is that the component I need to install or tools...

Thanks guys for your input.

I'd go with ASP.Net MVC. The scaffolding will do much of the plumbing work for you. You'll then need to enhance the look if you want and add some validation. MVC supports jQuery and jQuery UI out of the box. In fact, the templates add them in for you.
