I think the key word from your original question is "fancy". If your customers really expect a lot of glitter in the deliverable, then you probably do have something to gain from switching to WPF. |
See [ASP.NET Page Life Cycle Overview][1] if this is in a Page subclass. If you scroll down to the event list, that page advises you to use the PreInit event to create any dynamic controls. It's necessary to do that early to ensure that ASP.NET cleanly loads ViewState at the right stage, among other things.

You can find a comparison of the features in the various editions of Visual Studio 2008 [here][1]. The things that I find most annoying about the express edition are that you can't have multiple projects in a solution file, and you can't use add-ons like Resharper.

You've forgotten the ServerControl.
In my understanding it is like that:

As with the others I would most likely just do it as a one time quick fix in whatever manner works for you.
With these types of conversions, they are one off items, quick fixes, and the code doesn't have to be elegant, it just has to work. For these types of things I have done it many ways. |

If this is SQL Server, you can use the sys.columns table to find all of the columns of the original table. Then you can use dynamic SQL and the pivot command to do what you want. Look those up online for syntax. |
One way is to extend the specific control you want to double buffer and set the DoubleBuffered property inside the control's ctor.

Here's a basic regex technique that I've never managed to remember. Let's say I'm using a fairly generic regex implementation (e.g., grep or grep -e). If I were to do a list of files and match any that end in either ".sty" or ".cls", how would I do that?
