uwp：如何根据它的值更改listview项目的背景颜色？(uwp: how to change background color of listview item based on its value?)

编辑：UWP应用程序不是100％像WPF应用程序一样。

我有一个ListView的uwp应用程序。 在ListView中，我使用了DataTemplate和Tests类。 它显示测试和点的名称。

我想要完成的是一个触发器！ 检查点是否大于：50，然后将ListViewItem 的背景颜色更改为红色。

<ListView.ItemTemplate> <DataTemplate x:DataType="data:Tests"> <Grid> <TextBlock Text="{x:Bind Name}" /> <TextBlock Text="{x:Bind Points}" /> </Grid> </DataTemplate> </ListView.ItemTemplate>

Edit: UWP App is not 100% the same like the WPF App.

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.

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>

你可以用几种方法来做到这一点：

使用ItemContrainerStyleSelector ：我找到的示例 使用DataTemplateSelector ：我找到的示例 使用Converter ：我发现的示例将bool描述为可见性，但您可以根据需要更改它。

You can do this in several ways:

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.
