C# WPF数据网格滚动条

我正在尝试在必要时制作一个WPF数据网格来显示滚动条。 您可以在下面看到my user控件的基本XAML代码：

<Grid x:Name="Data" Grid.Column="0" VerticalAlignment="Stretch" Height="Auto" HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Expander Header="Route Setup" Grid.Row="0" VerticalAlignment="Top" Background="White">
</Expander>
<Expander Header="Select Locations" Grid.Row="1" VerticalAlignment="Top" Background="White">
</Expander>
<DataGrid Grid.Row="2" ItemsSource="{Binding Locations, Mode=TwoWay}" Height="Auto" AutoGenerateColumns="False" ScrollViewer.CanContentScroll="True" 
    ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Auto">
</DataGrid>

致意

杰伊解决了这个问题。我需要从名为“数据”的网格中的第三个

行定义中删除
Height=“Auto”
，从第三个
行定义中删除
Height=“Auto”
。至少有一行必须具有“*”高度（默认值）才能占用剩余的可用空间

    <Grid x:Name="LayoutRoot">
    <Grid.ColumnDefinitions >
        <ColumnDefinition Width="*" MinWidth="400" MaxWidth="600"/>
        <ColumnDefinition Width="9" />
        <ColumnDefinition Width="*" MinWidth="300" />
    </Grid.ColumnDefinitions>
    <GridSplitter x:Name="MainSplitter" HorizontalAlignment="Stretch" 
        VerticalAlignment="Stretch" Grid.Column="1"
        Margin="0" Width="9" Style="{DynamicResource gridSplitterVerticalStyle}"/>
    <ItemsControl Name="LeftRegion" Grid.Column="0" Background="Azure" Height="Auto" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch"  cal:RegionManager.RegionName="LeftRegion">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <Grid/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
    </ItemsControl>
    <ItemsControl  Name="RightRegion" Height="Auto" Background="DarkGreen"  VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Grid.Column="2" cal:RegionManager.RegionName="RightRegion">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <Grid/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
    </ItemsControl>
</Grid>
