在拆分ListView中再次显示列标题

Question

我有ListView ItemsPanel，如下所示：

        <ListView.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid Columns="2" />
            </ItemsPanelTemplate>
        </ListView.ItemsPanel>

对于ListView.View，我有GridView个多列。问题是我只能看到第一列中的列标题（UniformGrid）。我还需要在第二列中显示GridView的列标题。怎么做？

示例代码：

    <ListView>
        <ListView.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid Columns="2" />
            </ItemsPanelTemplate>
        </ListView.ItemsPanel>
        <ListView.View>
            <GridView>
                <GridView.Columns>
                    <GridViewColumn Header="Day" DisplayMemberBinding="{Binding Day}" />
                    <GridViewColumn Header="Month" DisplayMemberBinding="{Binding Month}" />
                    <GridViewColumn Header="Year" DisplayMemberBinding="{Binding Year}" />
                </GridView.Columns>
            </GridView>
        </ListView.View>
        <ListView.Items>
            <sys:DateTime />
            <sys:DateTime />
            <sys:DateTime />
        </ListView.Items>
    </ListView>

Answer 1

我试图让你期待的外表。所以我做了什么

• 创建了一个ItemsControl作为主容器
• 将UniformGrid设置为ItemsControl的项目面板
• 使用带有标题
的ListView为ItemsControl创建了一个数据模板
• 将ListView的ItemsSource绑定到ItemsControl中的Item
• 最重要的数据然后成为集合的集合

请随意根据您的使用情况调整样品

    <ItemsControl>
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid Columns="2" />
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <ListView ItemsSource="{Binding}">
                    <ListView.View>
                        <GridView>
                            <GridView.Columns>
                                <GridViewColumn Header="Day" DisplayMemberBinding="{Binding Day}" />
                                <GridViewColumn Header="Month" DisplayMemberBinding="{Binding Month}" />
                                <GridViewColumn Header="Year" DisplayMemberBinding="{Binding Year}" />
                            </GridView.Columns>
                        </GridView>
                    </ListView.View>
                </ListView>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
        <ItemsControl.Items>
            <x:Array Type="{x:Type sys:DateTime}">
                <sys:DateTime />
            </x:Array>
            <x:Array Type="{x:Type sys:DateTime}">
                <sys:DateTime />
            </x:Array>
            <x:Array Type="{x:Type sys:DateTime}">
                <sys:DateTime />
            </x:Array>
        </ItemsControl.Items>
    </ItemsControl>

第二种方法

    <ItemsControl>
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid Columns="2" />
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition/>
                        <ColumnDefinition/>
                        <ColumnDefinition/>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="auto"/>
                        <RowDefinition/>
                    </Grid.RowDefinitions>

                    <TextBlock Text="Day" Background="LightGray"/>
                    <TextBlock Text="Month" Grid.Column="1" Background="LightGray"/>
                    <TextBlock Text="Year" Grid.Column="2" Background="LightGray"/>

                    <TextBlock Text="{Binding Day}" Grid.Row="1"/>
                    <TextBlock Text="{Binding Month}" Grid.Column="1" Grid.Row="1"/>
                    <TextBlock Text="{Binding Year}" Grid.Column="2" Grid.Row="1"/>
                </Grid>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
        <ItemsControl.Items>
            <sys:DateTime />
            <sys:DateTime />
            <sys:DateTime />
        </ItemsControl.Items>
    </ItemsControl>
