双向绑定不适用于DataGridTextColumn WPF

因此,我有一个包含3列的表(位置,现有记录,已提交)。当用户单击特定行时,将显示一个弹出窗口,允许用户更改“已提交”的值。因此,当弹出窗口关闭时,我想在表中查看更新的值。但是,尽管该值已在数据库中更新,但事实并非如此。有人可以告诉我代码在哪里出错吗?

我遵循了this的回答,但没有帮助我。

我的查看代码:

<DataGrid.Columns>

   <DataGridTextColumn Width="Auto" Header="OnHand" Binding="{Binding Path= OnHand,Mode = TwoWay,UpdateSourceTrigger=PropertyChanged }" />

</DataGrid.Columns>

这是我填充网格的方式:

foreach (var item in inventoryList)
{

     items.Add(new InventoryDto { location = item.location.Name, OnHand = item.OnHand.ToString(), committed = item.committed.ToString() });

}
InventoryDataGrid.ItemsSource = items;

这是课程:

class InventoryDto : INotifyPropertyChanged
    {

        public string location { get; set; }
        public string onHand { get; set; }
        public string committed { get; set; }



        public InventoryDto()
        {

        }

        public InventoryDto(string location, string OnHand, string committed, string productId)
        {
            this.location = location;
            this.onHand = OnHand;
            this.committed = committed;

        }


        public string OnHand
        {
            get
            {
                return onHand;
            }
            set
            {
                onHand = value;
                OnPropertyChanged("OnHand");
            }
        }

        #region INotifyPropertyChanged Members

        public event PropertyChangedEventHandler PropertyChanged;
        private void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
        #endregion
    }
