为什么我不能在WPF数据网格中选择单元格？

I have a WPF datagrid that looks like the following:

我有一个WPF数据网格，如下所示：

<DataGrid x:Name="dataGridOrderItems" Margin="369,0,4,51" VerticalAlignment="Bottom" Height="405" Grid.Row="1"
    VerticalGridLinesBrush="LightGray"  HorizontalGridLinesBrush="LightGray" AlternatingRowBackground="Beige"  AlternationCount="2" SelectionMode="Single" 
    SelectionChanged="dataGridOutstandingOrders_SelectionChanged" AutoGenerateColumns="False" IsReadOnly="True" Grid.ColumnSpan="2">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Resource Name" Binding="{Binding ResourceName}" />
        <DataGridTextColumn Header="Quantity Ordered" Binding="{Binding Quantity}" />
        <DataGridTextColumn Header="Order Date" Binding="{Binding OrderDate, StringFormat=\{0:d\}}" />
        <DataGridCheckBoxColumn Header="Dispatched Resource" Binding="{Binding IsChecked}" />
        <DataGridTextColumn/>
    </DataGrid.Columns>
</DataGrid>

Even though the datagrid is enabled and I've specified a selection mode I can't click into any of the cells. What else am I missing?

即使数据网格已启用且我已指定选择模式，我也无法单击任何单元格。我还缺少什么？

Ended up resolving this one myself - it looks like I didn't have both selection modes. Updated (working XAML):

结束了我自己解决这个 - 看起来我没有两种选择模式。更新（工作XAML）：

<DataGrid x:Name="dataGridOrderItems" Margin="369,0,4,51" VerticalAlignment="Bottom" Height="405" Grid.Row="1"
VerticalGridLinesBrush="LightGray"  HorizontalGridLinesBrush="LightGray" AlternatingRowBackground="Beige"  AlternationCount="2" 
SelectionMode="Single" SelectionUnit="FullRow" 
AutoGenerateColumns="False" IsReadOnly="False" Grid.ColumnSpan="2">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Resource Name" Binding="{Binding ResourceName}" />
        <DataGridTextColumn Header="Quantity Ordered" Binding="{Binding Quantity}" />
        <DataGridTextColumn Header="Order Date" Binding="{Binding OrderDate, StringFormat=\{0:d\}}" />
        <DataGridCheckBoxColumn Header="Dispatched Resource" Binding="{Binding IsChecked}" />
        <DataGridTextColumn/>
    </DataGrid.Columns>
</DataGrid>

I think your isReadOnly property cause this one. After you change isReadOnly to 'False' to solve it.

我认为你的isReadOnly属性导致了这个。将isReadOnly更改为'False'后解决它。
