Windows8 Metro應(yīng)用開發(fā)之C# 2 - 布局控件Grid,Canvas,StackPanel(延續(xù)Silverlight)

1、Windows8 Metro應(yīng)用開發(fā)之C#（2）- 布局控件Grid,Canvas,StackPanel（延續(xù)Silverlight）介紹：在Metro中從Silverlight中保留下來(lái)了一些布局控件及一些新增的布局控件。本節(jié)主要講解從Silverlight中延續(xù)下來(lái)的布局控件Grid、Canvas及StackPanel，如果你有Silvelright或WPF基礎(chǔ)可以跳過(guò)本節(jié)。 Grid網(wǎng)格布局控件 定義由行和列組成的網(wǎng)格區(qū)域。Grid.xaml 1 <UserControl 2
