How do/can designers work with ASP.NET

On most projects I've been one, designers has produced HTML code, then developers turned it into ASP.NET, including master-pages etc that should really be a part of design.

After it has become ASP.NET, designers could not work on the code with their tools.

I know that a lot of the design of ASP.NET is made with the purpose of separating code and design, and in principle designers should be able to work on design aspects with the Visual Web Developer, but I've never seen a designer using VWD.

How is cooperation done in practice, an开发者_StackOverflowd what is about the best one can expect from a designer?

From someone who does both:
Most of the design should be done with CSS, so this isn't a problem. The layout of the page, therefore, comes down to elements with IDs and classes (simplistically speaking).
I try to keep these IDs and classes as is, and place ContentPlaceHolders inside them as needed, when possible, and create controls or skins with the right classes.
Optimally, designers and programmers should work together, and know each others limitations and requirements (this cannot always be done, sometimes these are done by different companies). I think most of the responsibility here lies on the developers - they need the right controls to get the expected output.
Frankly, a web designer should care about HTML and CSS, not about what server-side technology is used to deliver them. The best I would expect from a web designer is to write flexible CSS, that can take a view changes to the HTML structure without breaking (that is - extra divs or tables, as ASP.NET tends to do).

A good ASP.NET developer will intelligently use the set of controls available. For example, in most cases, the ListView will do everything the GridView can, and produce clean, SEO-friendly markup.

In the ASP.NET environment, I would encourage the use of Expression by designers. Business owners can avail of the new deal from Microsoft and obtain VS, Expression, etc., for $100 for three years.

I think both developers and designers have to embrace each others world for anything to work.

We are still stuck with the old fashioned way of the designer producing PSD documents and hopefully rendering them into HTML.

Then we take them over and convert them to .Net, then the designer requests a change and we go in circles for a while before coming to an acceptable solution.

It would be nice if the designer could integrate into the HTML of .Net easier but I don't see that happening for a while, not while Microsoft advocates using scripting in your development..

I've found that using ASP.NET MVC will make the designer's job much easier. Especially if you stay away from using things like HTML.RenderImage, and instead place an IMG tag on the page with <%= ViewData["MyImage"] %> as the src. This will allow the designer to see the html they like and understand, while giving you the flexibility to set the source(which is all the developer should be doing). The goal being to stay away from ASP.NET controls, which would confuse a designer, while still keeping their flexibility to develop quickly.
