wpf gridsplitter问题 - 双方缩小

Question

Gridsplitter麻烦:

我有一个:4列的网格

• 第0列包含一个包含3列的网格
• 第1列包含一个网格分析器
• 第2列包含宽度为20像素的堆叠面板
• 第3列包含一个包含3列的网格

当栅格切割器向左或向右移动时,两个面板收缩相同的量 - 一个应缩小,另一个应该增长.

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.如果你真的需要整件事,那我当然可以提供它.

谢谢你的帮助!

Answer 1

我遇到过同样的问题.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,你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

好吧，我现在看到你的问题了......基本上，你不能在将被控件更改的Width列上设置精确的值。相反，您只能在 上设置和/或属性，但请注意，您不能使用该符号。另外，查看下面的代码示例，您可以看到您可以为您的问题示例删除整个加载更多代码...这就是演示您的问题所需的全部内容（在我修复它之前）：WidthGridSplitterMinWidthMaxWidthColumnDefinition"*"

<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>
