C# ItemsControl、ListView、ListBox或DataGrid中可调整大小的行

在

ItemsControl

、

ListView

、

ListBox

或

DataGrid

上，是否有任何可能的方法可以调整行的大小

我能做我想要的东西的唯一方法是：

<UniformGrid Columns="1">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <SomeControlGoesHere />
        <GridSplitter Height="5" Background="Transparent" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Grid.Row="1" />
    </Grid>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <SomeControlGoesHere />
        <GridSplitter Height="5" Background="Transparent" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Grid.Row="1" />
    </Grid>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <SomeControlGoesHere />
        <GridSplitter Height="5" Background="Transparent" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Grid.Row="1" />
    </Grid>
</UniformGrid>

这是一个有3个部分的例子，我可以调整大小。我想使数字任意，并有数据绑定，并能够指定一个模板

我无法使用任何

ItemsControl

重新创建此项，因为项容器必须是

ContentControl

，而网格不是。如果网格被任何东西包裹，它的行为就不像我需要它那样

这些控件中有没有内置的方法来实现这一点

有没有其他方法可以创建这样的可调整大小的分区

---

更糟糕的是，是否有第三方控件可以执行此操作？

因此，我发现最好的方法是为此创建正确的网格

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <SomeControl />
    <GridSplitter Height="5" VerticalAlignment="Center" HorizontalAlignment="Stretch" Grid.Row="1" />
    <SomeControl Grid.Row="2" />
</Grid>

        {

        }

                    Background = new SolidColorBrush( Color.FromArgb( 255, 0, 0, 0 ) ),
                    VerticalAlignment = VerticalAlignment.Center,
                    HorizontalAlignment = HorizontalAlignment.Stretch,
                };
                SetRow( gridSplitter, Children.Count );
                Children.Add( gridSplitter );
            }

            RowDefinitions.Add( new RowDefinition
            {
                Height = new GridLength( 1, GridUnitType.Star ),
                MinHeight = 40,
            } );
            var contentPresenter = new ContentPresenter();
            contentPresenter.SetValue( ContentPresenter.ContentTemplateProperty, ItemTemplate );
            contentPresenter.Content = item;
