WPF SharedSizeGroup GridSplitter问题

我的答案来自 ms connect :

通常,您可以通过不使用SharedSizeGroup来解决此问题,而是将所有共享大小绑定到一个对象(例如,您的DataContext)上的单个属性:

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:my="clr-namespace:WpfApplication3"
        Height="350" Width="525" Title="MainWindow">

    <Window.DataContext>
        <my:MainWindowData Width0="1*" Width1="1*" />
    </Window.DataContext>

    <Window.Resources>

        <DataTemplate x:Key="dt">
         <Grid>
            <Grid.ColumnDefinitions>
             <ColumnDefinition Width="{Binding Path=Width0, Mode=TwoWay}" />
             <ColumnDefinition Width="Auto" />
             <ColumnDefinition Width="{Binding Path=Width1, Mode=TwoWay}" />
            </Grid.ColumnDefinitions>
            <Button Grid.Column="0" Content="{Binding Width0}" />
            <GridSplitter Grid.Column="1" Width="10" ResizeBehavior="PreviousAndNext" ResizeDirection="Columns" />
            <Button Grid.Column="2" Content="{Binding Width1}" />
         </Grid>
        </DataTemplate>

    </Window.Resources>

    <StackPanel>
        <ContentPresenter Content="{Binding}" ContentTemplate="{StaticResource dt}" />
        <ContentPresenter Content="{Binding}" ContentTemplate="{StaticResource dt}" />
    </StackPanel>

</Window>

其中width0和width1是匹配类型(gridlength)。它可以与任何类型的大小(固定、星型和自动)结合使用。

更新 :

或者,也许更好,您可以完全在XAML中进行,而不是绑定到DataContext。只需定义一个带有命名列的主网格(不一定是父网格,但需要某种方法来引用它),然后按名称绑定到它们。

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Height="350" Width="525" Title="MainWindow">

    <!-- shared sizing used only on fixed size columns therefore safe -->
    <!-- alternatively you can hardcode width of splitter column -->
    <Grid Name="masterGrid" Grid.IsSharedSizeScope="True">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="1*" Name="masterColumn0" />
            <ColumnDefinition Width="Auto" SharedSizeGroup="masterColumn1" />
            <ColumnDefinition Width="1*" Name="masterColumn2" />
        </Grid.ColumnDefinitions>
        <StackPanel Grid.ColumnSpan="3">
            <StackPanel.Resources>
                <DataTemplate x:Key="dt">
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="{Binding Path=Width, Mode=TwoWay, ElementName=masterColumn0}" />
                            <ColumnDefinition Width="Auto" SharedSizeGroup="masterColumn1" />
                            <ColumnDefinition Width="{Binding Path=Width, Mode=TwoWay, ElementName=masterColumn2}" />
                        </Grid.ColumnDefinitions>
                        <Button Grid.Column="0" Content="{Binding Path=Width, Mode=TwoWay, ElementName=masterColumn0}" />
                        <Button Grid.Column="2" Content="{Binding Path=Width, Mode=TwoWay, ElementName=masterColumn2}" />
                    </Grid>
                </DataTemplate>
            </StackPanel.Resources>
            <ContentPresenter ContentTemplate="{StaticResource dt}" />
            <ContentPresenter ContentTemplate="{StaticResource dt}" />
        </StackPanel>
        <GridSplitter Grid.Column="1" Width="10" ResizeBehavior="PreviousAndNext" ResizeDirection="Columns" ShowsPreview="True" />
    </Grid>

</Window>

这增加了使用所有网格共享的单个网格拆分器的好处。

我可以重新解释这个,老实说,它看起来像个虫子。具体来说,如果将列的宽度扩展到第一行,我就不能再将宽度减小到比另一行的宽度更大的程度。我想再试试这个,不过…不知道该怎么解决。

如果你觉得可以的话,试试这个解决方案(在Kaxaml,它工作得很好)。

<!-- Parent Grid -->
<Grid Grid.IsSharedSizeScope="True">

  <Grid.RowDefinitions>
    <RowDefinition></RowDefinition>
    <RowDefinition></RowDefinition>
  </Grid.RowDefinitions>

  <Grid.ColumnDefinitions>
    <ColumnDefinition SharedSizeGroup="A" Width="Auto"></ColumnDefinition>
    <ColumnDefinition Width="Auto"></ColumnDefinition>
    <ColumnDefinition SharedSizeGroup="C" Width="Auto"></ColumnDefinition>
  </Grid.ColumnDefinitions>

  <Label Grid.Column="0" Grid.Row="0">One-Left</Label>
  <Label Grid.Column="0" Grid.Row="1">Two-Left</Label>
  <GridSplitter Grid.Column="1" Grid.Row="0" Grid.RowSpan="2" Width="5" Background="DarkGray"></GridSplitter>
  <Label Grid.Column="2" Grid.Row="0">One-Right</Label>
  <Label Grid.Column="2" Grid.Row="1">Two-Right</Label>

</Grid>

希望这有帮助
