Ok, so we have clients and those clients get to customize their web facing page. One option we are giving them is to be able to change the color of a graphic (it's like a framish-looking bar) using one of those hex wheels or whatever. So, I've thought about it, and I don't know where to start. I am sending comps out this week to my xht...
I don't currently use ajax.net though I would be open to it if it is the only solution. I have a auto-complete control on screen that I am using to populate a asp.net dropdownlist with values through javascript (jQuery). I have had to use EnableEventValidation="false" to allow this.

I'm the only developer supporting a website that's a mix of classic asp and .NET. I had to add some .net pages to a classic asp application. This application requires users to login.

I have an ASP.Net 2.0 web site, using the DotNetNuke framework (4.09), and it will not compile, but when I hit the site in a browser, it works. Even the parts that don't compile will work.
