I created a sample where I bound the ItemsSource of the DataGrid to an ObservableCollection and from here you have two options.
我创建了一个示例，将 DataGrid 的 ItemsSource 绑定到 ObservableCollection，从这里您有两个选择。
- Set AutoGenerateColumns="False" on the DataGrid and set IsReadOnly="True" for all columns except the column you want to be editable you will set IsReadOnly="False".
- AutoGenerateColumns="True" (it is the default, so you could just remove the attribute from the XAML) and make the setters private in your ViewModel for all of the properties except the column you want to be editable.
- 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"。
- AutoGenerateColumns="True"（它是默认值，因此您可以从 XAML 中删除该属性）并在您的 ViewModel 中为所有属性设置私有的 setter，除了您要编辑的列。
Here is my sample code for option 1:
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>
