             xmlns:local="clr-namespace:West.StoreMgr.View"
             mc:Ignorable="d" 
             DataContext="{Binding Source={StaticResource Locator},Path=GoodsType}"
             d:DesignHeight="450" d:DesignWidth="800">
    <Grid>
        <Grid.RowDefinitions>

2、添加视图模型

using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Controls;

                    var old = view.Tag as GoodsType;
                    if (old == null) return;
                    var model = ServiceLocator.Current.GetInstance<EditGoodsTypeViewModel>();
