c# - WPF：如何冻结数据网格中的列标题

Question

如何DataGrid在我的WPF窗口中冻结我的列标题，以便当我向下滚动时，标题仍然可见。

[编辑]

这是我的XAML：

<ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Visible">
    <DataGrid Name="ModelsGrid" Background="Transparent" Foreground="Black"  RowHeight="30" ColumnWidth="100"  AutoGenerateColumns="False" ItemsSource="{Binding}">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Property ID" Binding="{Binding Path=Id}" />
            <DataGridTextColumn Header="Name" Width="Auto" Binding="{Binding Path=PropertyName}" />
            <DataGridTextColumn Header="Description" Width="Auto" Binding="{Binding Path=Description}" />
            <DataGridTextColumn Header="Access" Width="Auto" Binding="{Binding Path=Accessibility}" />
            <DataGridTextColumn Header="Type" Width="Auto" Binding="{Binding Path=Type}" />
            <DataGridTextColumn Header="Category" Width="Auto" Binding="{Binding Path=Category}" />
        </DataGrid.Columns>
    </DataGrid>
</ScrollViewer>

我只需要摆脱ScrollViewer它，它就解决了。

我只需要摆脱 ScrollViewer 就解决了。

Datagrid 有FreeColumnCount 属性- 将其设置为 1 看看会发生什么。

您可以使用嵌套滚动查看器来执行此操作。这是a of的Template属性设置器：StyleTargetType="DataGrid"

<Setter Property="Template">
  <Setter.Value>
    <ControlTemplate TargetType="DataGrid">

      <DockPanel Dock="Top" HorizontalAlignment="Stretch">

        <ScrollViewer DockPanel.Dock="Top" 
                      CanContentScroll="False" 
                      HorizontalScrollBarVisibility="Disabled" 
                      VerticalScrollBarVisibility="Disabled" 
                      Focusable="false" 
                      Padding="{TemplateBinding Padding}">

          <DockPanel Dock="Top" VerticalAlignment="Stretch">
            <DataGridColumnHeadersPresenter DockPanel.Dock="Top" Grid.Row="0"/>
            <ScrollViewer HorizontalScrollBarVisibility="Hidden" 
                          DockPanel.Dock="Top" 
                          VerticalScrollBarVisibility="Auto" 
                          VerticalAlignment="Stretch" 
                          CanContentScroll="False" 
                          Focusable="false" 
                          Padding="{TemplateBinding Padding}">
              <ItemsPresenter VerticalAlignment="Stretch"/>
            </ScrollViewer>
          </DockPanel>
        </ScrollViewer>
      </DockPanel>

    </ControlTemplate>
  </Setter.Value>
</Setter>

当然，ScrollViewer也可以设置样式以反映您的 UI 设计。

冻结 DataGrid 列非常困难，最好使用 DataGridView
