如何为ListBoxItem创建标头？

Question

我在我的应用程序中使用ListBox.ListBox有两列.我想为专栏制作一个标题.这是布局

  <Window.Resources>
    <Style x:Key="borderBase" TargetType="Border">
        <Setter Property="BorderBrush" Value="Black" />
        <Setter Property="BorderThickness" Value="1" />
    </Style>
</Window.Resources>
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="1*" />
        <RowDefinition Height="7*" />
    </Grid.RowDefinitions>
    <!--  Title  -->
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>

        <Border Style="{StaticResource borderBase}">
            <TextBlock Text="FirstName" />
        </Border>

        <Border Grid.Column="1" Style="{StaticResource borderBase}">
            <TextBlock Text="SecondName" />
        </Border>

    </Grid>

    <!-- Data -->
    <ListBox Grid.Row="1">
        <ListBox.ItemTemplate>
            <DataTemplate>

                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition />
                        <ColumnDefinition />
                    </Grid.ColumnDefinitions>

                    <Border Style="{StaticResource borderBase}">
                        <TextBlock Style="{StaticResource textBlockBase}" Text="{Binding FirstName}" />
                    </Border>

                    <Border Grid.Column="1" Style="{StaticResource borderRigth}">
                        <TextBlock Style="{StaticResource textBlockBase}" Text="{Binding SecondName}" />
                    </Border>
                </Grid>

            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

</Grid>

ListBox中的一些项目全部显示OK.但是当列表中的很多元素 - ListBox中的垂直滚动条可见时.然后标题并移动到列的宽度.

如何对齐列和标题的宽度？

WPF 仅为此目的提供了一些属性.您需要使用SharedSizeGroup和Grid.IsSharedSizeScope属性:

<Grid Grid.IsSharedSizeScope="True"><!-- Look HERE -->
    <Grid.RowDefinitions>
        <RowDefinition Height="1*" />
        <RowDefinition Height="7*" />
    </Grid.RowDefinitions>
    <!--  Title  -->
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition SharedSizeGroup="FirstNameColumn" /><!-- Look HERE -->
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Border Style="{StaticResource borderBase}">
            <TextBlock Text="FirstName" />
        </Border>
        <Border Grid.Column="1" Style="{StaticResource borderBase}">
            <TextBlock Text="SecondName" />
        </Border>
    </Grid>
    <!-- Data -->
    <ListBox Grid.Row="1">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition SharedSizeGroup="FirstNameColumn" />
                        <ColumnDefinition /><!--  Look Above HERE  -->
                    </Grid.ColumnDefinitions>
                    <Border Style="{StaticResource borderBase}">
                        <TextBlock Style="{StaticResource textBlockBase}" Text="{Binding FirstName}" />
                    </Border>
                    <Border Grid.Column="1" Style="{StaticResource borderRigth}">
                        <TextBlock Style="{StaticResource textBlockBase}" Text="{Binding SecondName}" />
                    </Border>
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

</Grid>

请访问MSDN上的Grid.IsSharedSizeScope附加属性页面以获取更多信息.

为什么这么复杂？只需使用GridViewColumn的"Header"属性......

 <ListView >
            <ListView.View>
                <GridView>
                    <GridViewColumn  Header="Id"/>
                    <GridViewColumn  Header="Name"/>
                </GridView>
            </ListView.View>
        </ListView>
