- by Goran

I think that subject summs it pretty well... I have created my custom validators that work great when I put them on page in design mode. However if I place them in a usercontrol, and then try to add this user control to the parent page via updatepanel, then my custom validators just won't trigger. They simply don't work. Does anyone have any clue on what I have to do here? .net 3.5

How significant is .NET 3.5 SP1 for WCF/REST?

- by Edward Tanguay

I just worked through a book on WCF and was surprised that it didn't even mention REST at all. Was REST an afterthought for WCF that was added in .NET 3.5 SP1 and hence not baked in well or is it well integrated? I assume that Silverlight and XBAPs can consume WCF with no problem or do they have some limitation due to their sandbox environments? I've been reading that some people are having problems getting WCF to play well with XBAP and I would assume there are similar problems with Silverlight.

How do I convert HTML to RTF (Rich Text) in .NET without paying for a component?

- by Josh Kodroff

Is there a free third-party or .NET class that will convert HTML to RTF (for use in a rich-text enabled Windows Forms control)? The "free" requirement comes from the fact that I'm only working on a prototype and can just load the BrowserControl and just render HTML if need be (even if it is slow) and that Developer Express is going to be releasing their own such control soon-ish. I don't want to learn to write RTF by hand, and I already know HTML, so I figure this is the quickest way to get some demonstrable code out the door quickly.
