wpf gridsplitter问题 - 双方缩小

Gridsplitter trouble:

I have a: grid with 4 columns

我有一个:4列的网格

• Column 0 contains a grid with 3 columns

第0列包含一个包含3列的网格

• Column 1 contains a gridsplitter

第1列包含一个网格分析器

• Column 2 contains a stackpanel of width 20 pixels

第2列包含宽度为20像素的堆叠面板

• Column 3 contains a grid with 3 columns

第3列包含一个包含3列的网格

When the gridsplitter is moved to either the left or right, BOTH panels shrink the same amount -- one should shrink and the other should grow.

当网格分割器向左或向右移动时,两个面板收缩相同的数量 - 一个应缩小,另一个应该增长。

I am hesitant to include the xaml, but you are going to ask for it, so here is an abridged version. I have only removed a few unrelated controls, and gutted the treeviews and listviews. If you really need the whole thing, then of course I can supply it.

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。如果你真的需要整个东西,那么我当然可以提供它。

Thanks for any help!

谢谢你的帮助!

Ok, I see your problem now... basically, you can't set an exact Width on a column who's Width will be changed by a GridSplitter control. Instead, you can only set MinWidth and/or MaxWidth property on the ColumnDefinition, but be aware that you can then not use the "*" notation. Also, looking at the code example below, you can see that you could have stripped out a whole load more code for your question example... this was all that was required to demonstrate your problem (before I fixed it):

好的,我现在看到你的问题...基本上,你不能在一个列上设置一个确切的宽度,其宽度将由GridSplitter控件改变。相反,您只能在ColumnDefinition上设置MinWidth和/或MaxWidth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,您可以看到您可能已经为您的问题示例删除了更多的代码...这就是演示您的问题所需的全部内容(在我修复它之前):

<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>

I had the same issue. When I moved one GridSplitter it would also move the other (Usually in the opposite direction.). I eventually discovered that I had forgotten to set a property of the GridSplitter. For a GridSplitter you MUST have both vertical and horizontal properties set ie...

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>
