仓库管理系统13--物资设置

1、添加窗体

2、设计UI界面

注意这个下拉框的绑定，你看到的选项是由displaymember决定，当你选择了哪个选项时，后台绑定这个选项的ID

4、运行程序

5、修改物资

1）添加窗体

2）UI布局

            <StackPanel Orientation="Horizontal" VerticalAlignment="Center"  Margin="0 10 0 10">

3）添加viewmodel

                        MsgWinHelper.ShowError("序号和名字不能为空！");
                        return;
                    }
                    Goods.GoodsTypeId = GoodsType.Id;
                    Goods.SpecId = Spec.Id;
                    var service = new GoodsService();
                    int count = service.Update(Goods);
                    if (count > 0)
                    {
                        MsgWinHelper.ShowMessage("修改成功！");
                        window.Close();
                    }
                    else

                });

                return command;
            }
        }


        //取消
        public RelayCommand<Window> CancelCommand

                {
                    window.Close();
                });

                return command;
            }
        }
    }
}

4）运行程序
