abp(net core)+easyui+efcore實現倉儲管理系統——ABP WebAPI與EasyUI結合增刪改查之六(三十二)

3. 在Visual Studio 2017的按F5運行，同時在「ABP.TPLMS.Web.Mvc」項目的Controller目錄中找到OrgsController.cs文件，在GetJsonTree中設置斷點。以下圖。咱們發現classlist對象中只有10條數據，而實際上咱們有12條數據。是否是因爲這個緣由形成的呢？框架

4. 咱們來看一下PagedOrgResultRequestDto對象paged，發現paged的屬性MaxResultCount=10，以下圖。Paged實例默認最多查詢10條記錄。post

5. 在Visual Studio 2017的「ABP.TPLMS.Web.Mvc」項目的Controller目錄中找到OrgsController.cs文件，代碼中添加最大查詢記錄數。代碼修改以下：測試
