WPF-具有三列的GridSplitter [英] WPF - GridSplitter with three columns

问题描述

我有一个带有3列网格的应用程序.第一列和第二列之间的网格拆分器工作正常.为了使拆分器位于第二列和第三列之间，我为拆分器创建了一个列. (因此，第三列实际上是第四列.)

I have an app with grid with 3 columns. The grid splitter between the first and second columns works just fine. To get the splitter over to be between the second and third columns I made a column for the splitter. (So now the the third column is really the fourth.)

当我调整大小时，其他列也会缩小.我认为这是因为我将它们设置为相对大小.但是我不知道如何解决.

When I resize the other columns also shrink. I assume that is because I have them set to be relative sized. But I don't know how to fix it.

这是我的问题的XAML Pad Ready示例.将其插入XAML键盘，然后尝试将最后一列的大小调整为较小.

Here is a XAML Pad Ready example of my issue. Plug this into XAML pad and then try to resize the last column to be smaller.

<Page

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="1*" />
            <ColumnDefinition Width="1*" />
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="1*" />
        </Grid.ColumnDefinitions>
        <StackPanel Background="#feca00" Grid.Column="0">
            <TextBlock FontSize="35" Foreground="#58290A"
                   TextWrapping="Wrap">Left Hand Side</TextBlock>
        </StackPanel>
        <GridSplitter Width="10" />
        <Border CornerRadius="10" BorderBrush="#58290A"
              BorderThickness="5" Grid.Column="1">
            <TextBlock FontSize="25" Margin="20" Foreground="#FECA00"
                   TextWrapping="Wrap">Right Hand Side</TextBlock>
        </Border>
        <GridSplitter Grid.Column="2" HorizontalAlignment="Right"  VerticalAlignment="Stretch" Width="5"></GridSplitter>
        <TabControl Grid.Column="3" Name="tabControl1">
            <TabItem Header="Add Links" Name="tabAddLinks">
                <Grid></Grid>
            </TabItem>
        </TabControl>
    </Grid>
</Page> 

感谢您的帮助！

有人建议在自己的列中同时使用两个拆分器可以解决此问题.我尝试过，现在第一个拆分器也像第二个拆分器一样缩小列.

It was suggested that having both splitters in their own columns might fix it. I tried that and now the first splitter also shrinks the columns like the second splitter does.

以下是该示例的XAML Pad代码:

Here is the XAML Pad code for that example:

<Page
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="1*" />
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="1*" />
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="1*" />
        </Grid.ColumnDefinitions>
        <StackPanel Background="#feca00" Grid.Column="0">
            <TextBlock FontSize="35" Foreground="#58290A"
                   TextWrapping="Wrap">Left Hand Side</TextBlock>
        </StackPanel>
        <GridSplitter Grid.Column="1" HorizontalAlignment="Right"  VerticalAlignment="Stretch" Width="5"></GridSplitter>
        <Border CornerRadius="10" BorderBrush="#58290A"
              BorderThickness="5" Grid.Column="2">
            <TextBlock FontSize="25" Margin="20" Foreground="#FECA00"
                   TextWrapping="Wrap">Right Hand Side</TextBlock>
        </Border>
        <GridSplitter Grid.Column="3" HorizontalAlignment="Right"  VerticalAlignment="Stretch" Width="5"></GridSplitter>
        <TabControl Grid.Column="4" Name="tabControl1">
            <TabItem Header="Add Links" Name="tabAddLinks">
                <Grid></Grid>
            </TabItem>
        </TabControl>
    </Grid>
</Page> 

推荐答案

尝试为两个拆分器设置HorizontalAlignment="Center"-不知道为什么为什么将其设置为正确"会导致这种情况发生棘手的，但是更改它对我有用:)

Try setting HorizontalAlignment="Center" for both splitters - no idea why having it set to "Right" should cause the behaviour to go so screwy, but changing it worked for me :)
