wpf - GridSplitter - 无限宽度

Question

简单的 GridSplitter 在某种意义上表现得很奇怪，当我将它向左移动超出 MinWidth 时，另一列会无限扩展。我在这里缺少什么？

<Grid>
    <Grid x:Name="holdergrid" HorizontalAlignment="Stretch">           
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width ="*" MinWidth="300"/>                
            <ColumnDefinition Width ="425"  MinWidth="300"/>
        </Grid.ColumnDefinitions>
        <Button Grid.Column="0" Content="Left"></Button>
        <Button Grid.Column="1" Content="Right"></Button>
        <GridSplitter Name="GridSplitterFolders" HorizontalAlignment="Left" Grid.Column ="1" Width ="10" ResizeBehavior="PreviousAndCurrent" />
    </Grid>
</Grid>

Answer 1

添加一个 Width 设置为 Auto 的 columnDefinition 以容纳 GridSplitter 本身并将 ResizeBehavior 更改为 PreviousAndNext。

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width ="*" MinWidth="300"/>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width ="425"  MinWidth="300"/>
    </Grid.ColumnDefinitions>
    <Label Content="Left" Grid.Column="0" />
    <GridSplitter HorizontalAlignment="Right" 
              VerticalAlignment="Stretch" 
              Grid.Column="1" ResizeBehavior="PreviousAndNext"
              Width="5" Background="#FFBCBCBC"/>
    <Label Content="Right" Grid.Column="2" />
</Grid>
