.net - 如何防止WPF GridSplitter更改网格的大小？

Question

WPF GridSplitter使我的网格比我的窗口更宽!

我有一个带有GridSplitter的WPF网格。如果我调整列的大小，则可以使网格比窗口宽且不可见。

它是这样开始的:

但是在加宽左列之后，我再也看不到右列(绿色):

我究竟做错了什么？如何防止GridSplitter更改网格的大小？

更新:

我还在为此苦苦挣扎。我现在尝试在网格内嵌套网格。那没有帮助。这是我的XAML ColumnDefinitions，RowDefinitions和GridSplitters ...

<Window ... >
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" MinWidth="150" />
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="*" MinWidth="400" />
        </Grid.ColumnDefinitions>
        <GridSplitter 
            ResizeDirection="Columns"
            ResizeBehavior="BasedOnAlignment"
            Grid.Column="1"
            HorizontalAlignment="Center"
            VerticalAlignment="Stretch"
            Width="2"
            Margin="0,5,0,5"
            Panel.ZIndex="1"/>
        <Grid Grid.Column="0">
            ...
        </Grid>
        <Grid Grid.Column="2">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" MinWidth="150" />
                <ColumnDefinition Width="Auto" />
                <ColumnDefinition Width="*" MinWidth="200" />
            </Grid.ColumnDefinitions>
            <GridSplitter 
                ResizeDirection="Columns"
                ResizeBehavior="PreviousAndNext"
                Grid.Column="1"
                HorizontalAlignment="Center"
                VerticalAlignment="Stretch"
                Width="2"
                Margin="0,5,0,5"
                Panel.ZIndex="1"/>
            <Grid Grid.Column="0">
                ...
            </Grid>
            <Grid Grid.Column="2">
                ...
            </Grid>
        </Grid>
    </Grid>
</Window>

我认为问题出在WebBrowser控件上。看到新问题:

如果调整了窗口的大小，使其宽度小于列的MinWidths的总和，则会看到列被切除，但是否则我无法重现您的问题:

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition MinWidth="150" Width="*"/>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition MinWidth="400" Width="*"/>
        </Grid.ColumnDefinitions>
        <GridSplitter
            Width="2"
            Grid.Column="1"
            HorizontalAlignment="Center"
            Margin="0,5,0,5"
            Panel.ZIndex="1"
            VerticalAlignment="Stretch"
            ResizeBehavior="BasedOnAlignment"
            ResizeDirection="Columns"/>
        <Grid Grid.Column="0">
            <Border Background="Red" Margin="5"/>
        </Grid>
        <Grid Grid.Column="2">
            <Grid.ColumnDefinitions>
                <ColumnDefinition MinWidth="150" Width="*"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition MinWidth="200" Width="*"/>
            </Grid.ColumnDefinitions>
            <GridSplitter
                Width="2"
                Grid.Column="1"
                HorizontalAlignment="Center"
                Margin="0,5,0,5"
                Panel.ZIndex="1"
                VerticalAlignment="Stretch"
                ResizeBehavior="PreviousAndNext"
                ResizeDirection="Columns"/>
            <Grid Grid.Column="0">
                <Border Background="Green" Margin="5"/>
            </Grid>
            <Grid Grid.Column="2">
                <Border Background="Blue" Margin="5"/>
            </Grid>
        </Grid>
    </Grid>
</Window>

展开红色列，它只会扩展到右边的列达到其MinWidth 400为止，它不会从页面启动。

您可能正在设置Window或最外面的Grid的其他属性，这将导致此行为...
