wpf - Gridsplitter 不调整大小

Question

我希望 GridSplitter 使 TreeView 更大，以便更容易查看 TreeView 的内容。似乎找不到合适的地方放置分路器

<Grid.ColumnDefinitions>
    <ColumnDefinition/>
    <ColumnDefinition Width="auto"/>
    <ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>

<Grid.RowDefinitions>
    <RowDefinition Height="auto"/>
    <RowDefinition/>
    <RowDefinition Height="auto"/>
    <RowDefinition />
    <RowDefinition Height="auto"/>
    <RowDefinition Height="auto"/>
</Grid.RowDefinitions>

<TextBlock Grid.Column="0" Grid.Row="0" Text="JSON String" Margin="5"/>
<TextBox Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="3"/>

<GridSplitter Grid.Column="0" Grid.ColumnSpan="3" Grid.Row="2" Height="5"         ResizeDirection="Rows" ResizeBehavior="PreviousAndNext" HorizontalAlignment="Stretch"/>

<TextBlock Grid.Column="0" Grid.Row="3" Text="C# Type" Margin="5"/>
<TreeView Grid.Column="0" Grid.Row="4" Grid.ColumnSpan="3" x:Name="outputTree" Margin="5"/>

Answer 1

将其设置为与第二个 TextBlock 相同的行并设置 ResizeBehavior至 PreviousAndNext我调整了您的一些行定义，以便根据需要进行调整

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="auto"/>
    </Grid.ColumnDefinitions>

    <Grid.RowDefinitions>
        <RowDefinition Height="auto"/>
        <RowDefinition />
        <RowDefinition Height="auto"/>
        <RowDefinition  />
    </Grid.RowDefinitions>

    <TextBlock Grid.Column="0" Grid.Row="0" Text="JSON String" Margin="5"/>
    <TextBox Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="3" Margin="5"/>


    <GridSplitter Grid.Column="0" Grid.ColumnSpan="3"  Grid.Row="2" Height="5"         ResizeDirection="Rows" ResizeBehavior="PreviousAndNext" VerticalAlignment="Top" HorizontalAlignment="Stretch"/>
    <TextBlock Grid.Column="0" Grid.Row="2" Text="C# Type" Margin="5"/>
    <TreeView Grid.Column="0" Grid.Row="3" Grid.ColumnSpan="3" x:Name="outputTree" Margin="5"/>
</Grid>
