XI, abnormal load solve

1. After you enter the appropriate information in the organization, "the organization added information" screen, click on the "Save" button. In the confirmation dialog box, click on the "OK" button. After successfully saved, and records in the database just more than 10, the list of tree during initialization, data can not be displayed. As shown below.

2.在“组织信息”列表界面中使用鼠标点击“添加”按钮，弹出“添加组织信息”界面，我们使用鼠标点击“上级组织”，无法显示任何数据。如下图。

3. 在Visual Studio 2017的按F5运行，同时在“ABP.TPLMS.Web.Mvc”项目的Controller目录中找到OrgsController.cs文件，在GetJsonTree中设置断点。如下图。我们发现classlist对象中只有10条数据，而实际上我们有12条数据。是不是由于这个原因造成的呢？

4. 我们来看一下PagedOrgResultRequestDto对象paged，发现paged的属性MaxResultCount=10，如下图。Paged实例默认最多查询10条记录。

5. 在Visual Studio 2017的“ABP.TPLMS.Web.Mvc”项目的Controller目录中找到OrgsController.cs文件，代码中添加最大查询记录数。代码修改如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Abp.AspNetCore.Mvc.Authorization;
using Abp.Web.Models;
using ABP.TPLMS.Controllers;
using ABP.TPLMS.Orgs;
using ABP.TPLMS.Orgs.Dto;
using ABP.TPLMS.Web.Models.Orgs;
using Microsoft.AspNetCore.Mvc;

            List<TreeJsonViewModel> jsonData = new List<TreeJsonViewModel>();
            List<OrgDto> classlist = orgs.Where(m => m.ParentId == parentId).ToList();

            classlist.ToList().ForEach(item =>
