uwp:如何根据值更改列表视图项的背景颜色?
问题描述：
UWP 应用与 WPF 应用并非 100% 相同.
UWP App is not 100% the same like the WPF App.
我有一个带有 ListView 的 uwp 应用程序.在 ListView 中，我使用了一个 DataTemplate 和 Tests 类.它显示测试和点的名称.
I have a uwp App with a ListView. In the ListView i use a DataTemplate with the class of Tests. It displays the name of the Test and Points.
我想要完成的是一个触发器！?检查点数是否大于即:50，然后将 ListViewItem 的背景颜色更改为红色.
What i want to accomplish is that a Trigger !? checks if the Points are greater than i.e.: 50 and then change the background color of the ListViewItem to red.
<ListView.ItemTemplate>
<DataTemplate x:DataType="data:Tests">
<Grid>
<TextBlock Text="{x:Bind Name}" />
<TextBlock Text="{x:Bind Points}" />
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
答
您可以通过多种方式做到这一点:
You can do this in several ways:
- 使用
ItemContrainerStyleSelector:示例 我发现 - 使用
DataTemplateSelector:我找到的样本 - 使用
Converter:示例 我发现它描述了 bool 到可见性，但您可以随意更改它.
- Use
ItemContrainerStyleSelector: the sample which I found - Use
DataTemplateSelector: the sample which I found - Use
Converter: the sample which I found describes bool to visibility, but you can change it like you want.
