如何在只读数据网格中使一列可编辑？

<DataGrid x:Name="dgLoadDtl" Height="315" Width="710" Grid.Row="0" 
                  HorizontalAlignment="Left" VerticalAlignment="Bottom"  
                  Style="{DynamicResource StyleDatagrid}" 
                  IsReadOnly="true">

            <DataGrid.Columns>                    

                <DataGridTextColumn Foreground="Black" Width="60" Header="Sctn" Binding="{Binding Sctn, Mode=TwoWay}" IsReadOnly="false" />                    
                <DataGridTextColumn Foreground="Black" Width="140" Header="CustName"  Binding="{Binding CustName, Mode=TwoWay}" />
                <DataGridTextColumn Foreground="Black" Width="140" Header="Address"  Binding="{Binding Address1, Mode=TwoWay}" />
                <DataGridTextColumn Foreground="Black" Width="50" Header="Bulk   or Bag"  Binding="{Binding BulkorBag, Mode=TwoWay}" />
                <DataGridTextColumn Foreground="Black" Width="80" Header="ProdCode" Binding="{Binding ProdCode, Mode=TwoWay}" />
                <DataGridTextColumn Foreground="Black" Width="80" Header="MedCode" Binding="{Binding MedCode, Mode=TwoWay}" />

我创建了一个示例,其中我将DataGrid的ItemsSource绑定到ObservableCollection,从这里您有两个选项.

1. 在DataGrid上设置AutoGenerateColumns ="False",并为除要编辑的列之外的所有列设置IsReadOnly ="True",您将设置IsReadOnly ="False".
2. AutoGenerateColumns ="True"(这是默认设置,因此您可以从XAML中删除该属性)并在ViewModel中为所有属性设置私有设置,除了您想要编辑的列.

这是我的选项1的示例代码:

<DataGrid x:Name="dgLoadDtl" Grid.Row="0" HorizontalAlignment="Left" VerticalAlignment="Top" ItemsSource="{Binding MyData}" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Foreground="Black" Width="60" Header="Sctn" Binding="{Binding Sctn, Mode=TwoWay}" IsReadOnly="false" />
        <DataGridTextColumn Foreground="Black" Width="140" Header="CustName"  Binding="{Binding CustName, Mode=TwoWay}" IsReadOnly="True"/>
        <DataGridTextColumn Foreground="Black" Width="140" Header="Address"  Binding="{Binding Address1, Mode=TwoWay}" IsReadOnly="True"/>
        <DataGridTextColumn Foreground="Black" Width="50" Header="Bulk   or Bag"  Binding="{Binding BulkorBag, Mode=TwoWay}" IsReadOnly="True"/>
        <DataGridTextColumn Foreground="Black" Width="80" Header="ProdCode" Binding="{Binding ProdCode, Mode=TwoWay}" IsReadOnly="True"/>
        <DataGridTextColumn Foreground="Black" Width="80" Header="MedCode" Binding="{Binding MedCode, Mode=TwoWay}" IsReadOnly="True"/>
    </DataGrid.Columns>
</DataGrid>
