始终禁用WPF DataGrid垂直ScrollBar

标签: c# wpf xaml datagrid scrollbar

我在UserControl中有DataGrid。 Datagrid绑定到ItemsSource,包含50个项目(50行)。 UserControl Width和Height设置为auto。如何在不指定DataGrid的高度和宽度的情况下启用ScrollBar?也许我想念一些东西,因为此时设计师告诉我我的DataGrid高度是5000(基于自动计算),这就是ScrollBar没有显示的原因。我希望我的DataGrid适合主窗口容器 - 具有星号的网格行。 我不想使用固定大小,因为我想在不同的屏幕分辨率上使用此视图。

                </DataGrid.Columns>
            </DataGrid>
    </Grid>
</Grid>

这是UserControl所在的View

<Window x:Class="Treasury7MD.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Title="MainWindow" WindowState="Maximized">
<Grid>

    <Grid Name="g" >
        <Grid.RowDefinitions>
            <RowDefinition MaxHeight="20"></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
            <RowDefinition Name="x" Height="*" MinHeight="100"></RowDefinition>

        </Grid.RowDefinitions>
        <Button Content="Collapse" Click="Button_Click"></Button>
        <views:OrganizationInfoView x:Name="z" Grid.Row="1"></views:OrganizationInfoView>
        <ScrollViewer Grid.Row="2" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" >

                <views:Form7MDTableHeadeView Grid.Row="2" ></views:Form7MDTableHeadeView>

        </ScrollViewer>
    </Grid>
   </Grid>

移除了ScrollViewer,其中包含UseControl和DataGrid的ScrollBar按预期工作。
