Another opportunity I had at MIX09 was to talk to the guys from DevExpress about the controls they are working on. Azret Botash explains how they are going after the features that people say can't be done and doing them. In this video he demos their Silverlight-based Rich text Editor along with their WPF-based Datagrid.

The rich text editor for Silverlight looks interesting!

EDIT: Just noticed that's my colleague Charles discussing with @IanET right behind Azret

That text editor is neat. Too bad Silverlight doesn't support printing or right click menus.

Actually you can handle the right click to do context menus, just with a bit of trickery.

But you shouldn't have to. Cut/Copy/Paste on a textbox context menu has been a standard feature in Windows for almost 15 years. If MS expects Silverlight LOB apps to compete with desktop apps or even plain HTML forms they need to include stuff like this by default.

Yea def, that and supporting dragging and dropping onto (and out of?) silverlight.. when asked they said it was a security issue.. more like an excuse.

Rich text layout is something you can do in Silverlight, but because of the absence of the FormattedText class you have to do a lot of extra, quite hacky, work. You can only 'measure' text by creating a TextBlock object and then testing it's ActualWidth property. So you have to add your text to it one word at a time and see when the line gets too long for the space you have in your layout, take the last word back out, position it in your container and repeat. And you have to sort-of guess the line spacing and baseline heights because there's no font metrics class.

I'm pretty staggered that FormattedText is still not in Silverlight 3 beta. Somebody needs to get Bill Hill on the Silverlight team's case because right now Silverlight is just for stupid animations - I can't take any UI technology seriously when it doesn't take text formatting seriously. Right now Silverlight is barely more powerful than AJAX as far as text rendering is concerned.
