Matthias Shapiro demonstrates how to use WrapPanel and DockPanel in your Windows Phone 7 application.
I’m currently working on porting the run-away hit mobile application ShopSavvy to Windows Phone 7 (sign up to be a beta tester) and one of the things I really wished I had was the WrapPanel.
(For those who are new to Silverlight/WPF/Windows Phone 7, the WrapPanel stacks UI elements either horizontally or vertically like the StackPanel except that, when it hits the panel limit it… wait for it… wraps and starts stacking in a new column/row. Handy.)
I found a way to add it with the Silverlight Toolkit, but doing that added 140 Kb to my application. Maybe I’m just stuck in the world of J2ME, but adding 140 Kb to my mobile app isn’t OK if I can help it.
