Question

如何获得一个网格来填充标签项的下半部分，并使尺寸正确？（我个人称这个区域为页面）。现在，我的布局根目标有一个网格，然后是一个带有几个标签的标签控件。我试图将网格拖放到选项卡控件上;但是，它始终设置为我最初为其创建的固定大小。

  <Grid x:Name="LayoutRoot" Margin="0,0,-1,0" Grid.IsSharedSizeScope="True">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="4*"/>
        <ColumnDefinition Width="1497*"/>

Answer 1

以下是一个向您展示的小例子：

<Grid>
    <TabControl>
        <TabItem Header="Whole Row Tab">
            <Grid Background="Blue">
                <TextBlock Text="I'm in the whole of this tab" />
            </Grid>
        </TabItem>
        <TabItem Header="Half Row Tab">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition />
                    <RowDefinition />
                </Grid.RowDefinitions>
                <Grid Grid.Row="1" Background="Red">
                    <TextBlock Text="I'm in the bottom half of this tab" />
                </Grid>
            </Grid>
        </TabItem>
        <TabItem Header="Another Half Row Tab">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                </Grid.RowDefinitions>
                <Grid Grid.Row="1" Background="Red">
                    <TextBlock Text="I'm in the bottom half of this tab" />
                </Grid>
            </Grid>
        </TabItem>
        <TabItem Header="Varied Row Tab">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*" />
                    <RowDefinition Height="2*" />
                    <RowDefinition Height="*" />
                </Grid.RowDefinitions>
                <Grid Grid.Row="0" Background="Green">
                    <TextBlock Text="I'm in the top quarter of this tab" />
                </Grid>
                <Grid Grid.Row="3" Background="Green">
                    <TextBlock Text="I'm in the bottom quarter of this tab" />
                </Grid>
            </Grid>
        </TabItem>
    </TabControl>
</Grid>

Answer 2

对于Grid下面的TabItem，请尝试设置您的定义，如下所示：

<Grid.RowDefinitions>
    <RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
    <ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>

对于TreeView定义，我将其更改为以下内容：

<TreeView x:Name="FileMaintTreeView" Background="#FF747474" BorderBrush="#FF0090FD" SelectedItemChanged="FileMaintTreeView_SelectedItemChanged" Grid.Column="0" Grid.Row="0">

（我删除了诸如边距和诸如此类的东西，如果你愿意，可以把它们放回去......

这至少会让你的TreeView填满整个TabItem。

如果您希望TabItem在页面上显示其他内容...让我们在TreeView旁边说一些控件，那么您可以添加另一个ColumnDefinition。宽度=“*”表示它将填满整个剩余空间。 Width =“Auto”表示它只会填充嵌套在该列/行中的控件的大小。

对我来说，最后，我通过添加以下设置从TabControlStyle.xaml（样式文件）中找到了原因：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style x:Key="TabControlStyle" TargetType="{x:Type TabControl}">
        <Style.Resources>
            <Style TargetType="{x:Type TabItem}">

                <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
                <Setter Property="VerticalContentAlignment" Value="Stretch"/>

                </Setter>
            </Style>
        </Style.Resources>

    </Style>
</ResourceDictionary>
