GridSplitter不可拖

Question

我有一个有一个分配器的网格和两个TreeVeiw的。

我一直无法让分离器移动和调整大小的两棵树。我试着在相关问题上改变了几个选择，但这些都没有帮助。我做错什么了？

        <Grid 
            Grid.Column="0" 
            HorizontalAlignment="Stretch" 
            Name="grid2" 
            VerticalAlignment="Stretch" 
            Background="White">
            <Grid.RowDefinitions>
                <RowDefinition Height="*" />
                <RowDefinition Height="5" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>
            <TreeView 
                Grid.Row="0"
                Height="Auto"
                HorizontalAlignment="Stretch"
                Name="treeView1"
                VerticalAlignment="Stretch"
                Width="Auto" />
            <GridSplitter 
                Grid.Row="1"
                Grid.RowSpan="2"
                ResizeDirection="Rows"
                Height="5"
                HorizontalAlignment="Stretch"
                Name="gridSplitter2"
                VerticalAlignment="Top"
                Width="Auto"
                ResizeBehavior="PreviousAndNext" />
            <TreeView 
                Grid.Row="2"
                Height="Auto"
                HorizontalAlignment="Stretch"
                Name="treeView2"
                VerticalAlignment="Stretch"
                Width="Auto" />
        </Grid>

Answer 1

正如Novitch S正确地说的那样，我只需将Grid.RowSpan从GridSplitter中删除。
