RDIFramework.NET ━ .NET快速信息化系统开发框架 V3.2->Web版本模块管理界面新增模块排序功能

　　模块（菜单）的排序是每个系统都必须要有的功能，我们框架模块的排序在业务逻辑中已经体现。

　　WinForm版本可以直接在界面上对模块进行排序以控制模块展示的顺序。Web版本在3.2版本中也新增了直接可以模块管理界面对模块进行排序的人性化操作，大大的方便了管理人员。模块的排序在模块管理主界面分页按钮的右侧如下图所示。

　　三个按钮功能分别为：上移、下移、确认修改

WebMVC部分，模块排序功能代码参考：

/// <summary>
  /// 保存模块排序功能
  /// </summary>
  /// <param name="parentId">父节点</param>
  /// <param name="rows">数据行</param>
  /// <returns></returns>
  [HttpPost]
  [ValidateInput(false)]
  [LoginAuthorize]

              }
 
              var moduleNewSort = new List<KeyValuePair<string, object>>();
              //把json字符串转换成对象
              List<PiModuleEntity> listRows = rows?.JonsToList<PiModuleEntity>();

                      }
                  }
