Question

Gridsplitter麻烦：

我有一个：4列的网格

第0列包含3列
第1列包含gridsplitter
第2列包含宽度为20像素的堆叠面板
第3列包含3列

当栅格切割器向左或向右移动时，两个面板收缩的量相同 - 一个应缩小，另一个应该缩小。

我对包含xaml犹豫不决，但你会要求它，所以这里是一个删节版本。我只删除了一些不相关的控件，并删除了treeviews和listviews。如果真的需要整个事情，那么我当然可以提供它。

感谢您的帮助！

当然，可以随意提出更好的方法来做任何事情:) - 我还在学习。

Answer 1

我有同样的问题。当我移动一个GridSplitter时，它也会移动另一个（通常是相反的方向）。我最终发现我忘了设置GridSplitter的属性。对于GridSplitter，您必须设置垂直和水平属性，即......

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <GridSplitter Grid.Column="1" Width="2" 
        VerticalAlignment="Stretch" HorizontalAlignment="Center"/>
</Grid>

Answer 2

好的，我现在看到了您的问题...基本上，您无法在Width控件更改Width的列上设置精确的GridSplitter。相反，您只能在MinWidth上设置MaxWidth和/或ColumnDefinition属性，但请注意，您不能使用"*"表示法。另外，查看下面的代码示例，您可以看到可以为您的问题示例删除了更多的代码...这就是证明您的问题所需的全部内容（在此之前）修好了）：

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" MinWidth="150" />
        <ColumnDefinition Width="5" />
        <ColumnDefinition Width="20" />
        <ColumnDefinition Width="*" MinWidth="150" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Rectangle Grid.Column="0" Fill="PowderBlue" />
    <GridSplitter Grid.Column="1" Background="Black" HorizontalAlignment="Stretch" />
    <Rectangle Grid.Column="2" Fill="Red" Height="100" />
    <Rectangle Grid.Column="3" Fill="Purple" />
</Grid>
