Just recently RAD was a modern abbreviation. Everybody was trying hard to make its tool fit the Rapid Application Development lifestyle. That life was so easy...
Now it is the XXI century. It brought us Canvas, StackPanel and Grid in Silverlight. They are newborns, they don't know what RAD means. But there are some controls born with the memory of the previous life and they feel your pain. You want them every time you need to write XAML just to modify your layout a little. And if you have a blank canvas in front of you, you understand that you will have to write a long story :-)
One such piece of technology - LayoutControl - uses modern advances without forgetting the easy RAD life of the past. Yes, you don't need to write any XAML with it. Actually you don't need a keyboard at all.
Don't believe us? Try it yourself! Just go to Area51 and click the LayoutControl link in the Controls group box. Preview the future of Silverlight layout management now.
