WPF DataGrid水平滚动条未显示 [英] WPF DataGrid horizontal scrollbar not showing

问题描述

我用4列创建了简单的DataGrid，这些列超出了DataGrid的范围，并且没有显示水平滚动条。我尝试为每列设置宽度，但没有任何改变。这是我的XAML：

I have created simple DataGrid with 4 columns, which go outside the bounds of DataGrid, and horizontal scrollbar is not showing. I tried setting width to each column but nothing changed. Here is my XAML:

<Window x:Class="WPFTest.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="300">
    <Grid>
        <DataGrid Height="200" Width="200" HorizontalScrollBarVisibility="Visible">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Column 1" />
                <DataGridTextColumn Header="Column 2" />
                <DataGridTextColumn Header="Column 3" />
                <DataGridTextColumn Header="Column 4" />
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
</Window>

这就是我得到的：

我也尝试过用ScrollViewer包装DataGrid。没有。我该如何使滚动条出现？

I have also tried wrapping DataGrid with ScrollViewer. Nothing. How can I make scrollbar appear?

推荐答案

我认为当 Datagrid 为空， ScrollViewer 无法处理任何内容。尝试通过添加 ItemsSource 来填充列，因此应该显示滚动：）

I think that when the Datagrid is empty, the ScrollViewer doesn't handle anything. Try to fill the columns by adding an ItemsSource, the scrolling should therefore appear :)
