重新想象 Windows 8 Store Apps (7) - 控件之布局控件: Canvas, Grid, StackPanel, VirtualizingStackPanel, WrapGrid, VariableSizedWrapGrid



作者:webabcd


介绍
重新想象 Windows 8 Store Apps 之布局控件

  • Canvas - 绝对定位式布局
  • Grid - 网格式布局
  • StackPanel - 流式布局
  • VirtualizingStackPanel - 仅能用于 ItemsControl
  • WrapGrid - 仅能用于 ItemsControl
  • VariableSizedWrapGrid - 用于 Wrap 子元素集合



示例
1、Canvas 的 Demo
