WPF SharedSizeGroup GridSplitter问题

Question

我希望使用Grid作为我的顶级布局.网格将有1列和n行.Grid中的每一行还应包含一个Grid,该Grid应包含3列和1行.在第二列是GridSplitter,我试图使用SharedSizeGroup,这样就可以改变所有嵌套网格中第一列的大小.

这就是我所拥有的...它的工作原理!! ......很好......如果你点击分离器并调整大小而不放手它可以工作......但出于某种原因,如果你调整大小并放开鼠标,然后尝试使用不同的行调整大小,似乎"坚持".

有任何想法吗？

<!-- Parent Grid -->
<Grid Grid.IsSharedSizeScope="True">
    <Grid.RowDefinitions>
        <RowDefinition></RowDefinition>
        <RowDefinition></RowDefinition>
    </Grid.RowDefinitions>

    <!-- First Grid -->
    <Grid Grid.Row="0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition SharedSizeGroup="A" Width="Auto"></ColumnDefinition>
            <ColumnDefinition SharedSizeGroup="B" Width="Auto"></ColumnDefinition>
            <ColumnDefinition SharedSizeGroup="C" Width="Auto"></ColumnDefinition>
        </Grid.ColumnDefinitions>

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

    <!-- Second Grid -->
    <Grid Grid.Row="1">
        <Grid.ColumnDefinitions>
            <ColumnDefinition SharedSizeGroup="A" Width="Auto"></ColumnDefinition>
            <ColumnDefinition SharedSizeGroup="B" Width="Auto"></ColumnDefinition>
            <ColumnDefinition SharedSizeGroup="C" Width="Auto"></ColumnDefinition>
        </Grid.ColumnDefinitions>

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

</Grid>

从ms连接重新发送我的答案:

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

<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).它适用于任何类型的尺寸(固定,星形和自动)任意组合.

更新:

或者也许更好,而不是绑定到DataContext,你可以纯粹在XAML中.只需定义一个主网格(不一定是父网格,但您需要某种方式来引用它),然后使用命名列绑定它们.

<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分割器的好处.
