c# - WPF 对网格中的单个行列使用 GridSplitter

Question

我想让 GridSplitter 只调整一个单元格的大小(实际上对于 WPF Grid 来说，这本身不是正确的术语，我们称其为单独的 Grid[r][c])以及要调整其相邻单元格的大小。

这是我尝试过的:

<Grid>
        <Grid.RowDefinitions>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition></ColumnDefinition>

            <ColumnDefinition></ColumnDefinition>

            <ColumnDefinition></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <Border Grid.IsSharedSizeScope="True"  Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="0" Grid.Column="0">
            <TextBlock>Testing 1</TextBlock>
        </Border>
        <Border Grid.IsSharedSizeScope="True"  Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="0" Grid.Column="1">
            <TextBlock>Testing 2</TextBlock> </Border>
        <Border Grid.IsSharedSizeScope="True"  Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="0" Grid.Column="2">
            <TextBlock>Testing 2</TextBlock>
        </Border>
        <Border Grid.IsSharedSizeScope="True" Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="1" Grid.Column="0">
            <TextBlock>Testing 3</TextBlock>
        </Border>
        <Border Grid.IsSharedSizeScope="True"  Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="1" Grid.Column="1">
            <TextBlock>Testing 4</TextBlock></Border>
        <Border Grid.IsSharedSizeScope="True"  Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="1" Grid.Column="2">
            <TextBlock>Testing 5</TextBlock></Border>
        <Border Grid.IsSharedSizeScope="True"  Margin="2" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="3" Grid.Column="0">

我希望它的行为方式是调整网格中单个单元格的大小。

1. 应用启动时

通过网格分割器调整大小时:

调整大小后:

我希望仅调整 Grid[ 0][ 0] 和 Grid[ 0][ 1] 的大小

Answer 1

你有 3 列和 3 行，而不是每行内有 3 列， 试试这个:

<Grid  >
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
    </Grid.RowDefinitions>
    <Grid Grid.Row="0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <GridSplitter Grid.Column="0"/>
        <GridSplitter Grid.Column="1"/>
        <GridSplitter Grid.Column="2"/>
    </Grid>
    <Grid Grid.Row="1">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>

    </Grid>
    <Grid Grid.Row="2">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>   
    </Grid>
</Grid>
