在uwp中的Listview组

Question

我有一个简单的视图ListView,我希望ListView有两个组,一组用于具有属性的项目,complete= 1另一组用于complete= 0.

这是我的班级:

public class myClass
{
    public string name{ get; set; }
    public bool complete{ get; set; }
}

这是我的XML:

<ListView x:Name="MasterListView">
    <ListView.GroupStyle>
        <GroupStyle >
            <GroupStyle.HeaderTemplate>
            </GroupStyle.HeaderTemplate>
        </GroupStyle>
    </ListView.GroupStyle>
</ListView>

<DataTemplate x:Key="MasterListViewItemTemplate" x:DataType="model:myClass">
    <TextBlock Margin="0,5,5,5" Text="{x:Bind name}" FontSize="20" Style="{ThemeResource BaseTextBlockStyle}" />
</DataTemplate>

我尝试了一些例子但我找不到任何东西.

Answer 1

我有一个带ListView的简单视图,我想ListView有两个组,一个用于属性complete = 1的项目组和另一个用complete = 0的组.

首先,将CollectionViewSource用于显示可以分组或排序的项目列表的内容.

<Page.Resources>
    <CollectionViewSource x:Key="cvs" x:Name="cvs" IsSourceGrouped="True" />
</Page.Resources>

然后,获取数据,将数据分组并将分组数据设置为后面的代码中的CollectionViewSource.

以下是我验证的示例代码:

MainPage.xaml中

<Page.Resources>
    <!--Use a collection view source for content that presents a list of items that can be grouped or sorted.-->
    <CollectionViewSource x:Key="cvs" x:Name="cvs" IsSourceGrouped="True" />
</Page.Resources>

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <ListView Background="White" Foreground="Black" SelectionMode="None" ItemsSource="{Binding Source={StaticResource cvs}}">
        <ListView.ItemTemplate>
            <DataTemplate>
                <StackPanel Margin="0.5">
                    <TextBlock Text="{Binding Path=Name}" />
                </StackPanel>
            </DataTemplate>
        </ListView.ItemTemplate>
        <ListView.GroupStyle>
            <GroupStyle>
                <GroupStyle.HeaderTemplate>
                    <DataTemplate>
                    </DataTemplate>
                </GroupStyle.HeaderTemplate>
            </GroupStyle>
        </ListView.GroupStyle>
    </ListView>
</Grid>

MainPage.xaml.cs中

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();
        //Get the data
        List<MyClass> myClasses = new List<MyClass>();
        myClasses.Add(new MyClass { Name = "A", Complete = false });
        myClasses.Add(new MyClass { Name = "B", Complete = true });
        myClasses.Add(new MyClass { Name = "C", Complete = true });
        myClasses.Add(new MyClass { Name = "D", Complete = false });
        myClasses.Add(new MyClass { Name = "E", Complete = true });
        myClasses.Add(new MyClass { Name = "F", Complete = false });
        //Group the data
        var groups = from c in myClasses
                     group c by c.Complete;
        //Set the grouped data to CollectionViewSource
        this.cvs.Source = groups;
    }
}

以下是输出:
