如何编写在GridView(XAML-Win8)组中流动项目的
代码,如下图所示？
我目前有一个自定义TemplateSELEctor,为第一个项目选择一个不同的(更大)模板,但是这里指定的流程：
@H_
502_4@<GroupStyle.Panel>
<ItemsPanelTemplate>
<q42:WrapPanel Orientation="Horizontal" Width="440" Margin="0,80,0"/>
<!-- also tried VariableSizedWrapGrid -->
</ItemsPanelTemplate>
</GroupStyle.Panel>
类似地包装项目1到3,但是然后将项目4放置在项目6的位置,而不填写项目4和5.
问题变成;我如何编写类似于css的代码：
@H_
502_4@.item
{ display: inline-block; }
.item1
{ float: left; }
,这将使物品像我想要的那样流动？
