切换到服务器端分页后显示网格数据

问题描述 投票:0回答:1

我正在将我的应用程序转换为使用带有 Kendo Grid UI 的服务器端分页。 在将 serverPaging 切换为 true 之前,我正确地显示了网格内容,并在客户端进行分页。 然而,一旦我打开服务器分页,我的数据就不再可见。 我已经检查了网络调用,并且我的数据正在按预期返回(总共 8 条记录中只有 2 条记录),但我没有在网格中看到它。

这是网格构建:

$v.KendoGrid.makeGrid(gridName, {
  columns: [
    { field: 'IdentifierCode', title: 'User Name' },
    { field: 'CompanyName', title: 'Company' },
    { field: 'Email', title: 'Email' }
  ],
  dataSource: {
    pageSize: 2,
    schema: {
      data: 'Data', // records are returned in the data section of the response
      model: {
        id: 'Id',
        fields: {
          IdentifierCode: { type: 'string' },
          CompanyName: { type: 'string' },
          Email: { type: 'string' }
        }
      },
      total: 'Total'    // total number of records are in the total section of the response
    },
    serverPaging: true,
    transport: {
      read: {
        url: window.urlConfigs.root + "Security/UserAccount/PagedListing"
        dataType: "json",
        type: "GET"
      }
    }
  },
  editable: false,
  filterable: true,
  height: 464,
  pageable: true,
  scrollable: true,
  sortable: true
});

这是 MVC 控制器方法:

public ActionResult PagedListing(int pageSize, int skip)
{
    var entities = ReadRepo.All();
    var total = entities.Count();
    var data = entities.Skip(skip).Take(pageSize).Select(MapEntityToViewModel).ToList();

    return Json(new { Total = total, Data = data }, JsonRequestBehavior.AllowGet);
}

这是我通过网络调用返回的数据:

{"Total":8,"Data":[{"Id":"928f0bb2-608b-417b-bf6e-e5c58f85fec2","IdentifierCode":"admin","FirstName":"Administrator","MiddleName":"of","MiddleNameHuman":"of","LastName":"GasStream","DisplayName":"Administrator of GasStream","Email":"[email protected]","IsExternal":false,"UserTypeHuman":"Internal","CompanyId":"75bb05a4-1ec2-4042-aeba-a229008aca9f","CompanyName":"Entessa Pipeline & Terminal, MLP","CompanyIdentifierCode":"SHA","Password":"wFg/a/NEU6WM8z4YZBUduitIDROfeFz/+Za6leAHnBE=","PasswordChanged":false,"ForceNewPasswordFlag":false,"Settings":[],"RoleGroups":[]},{"Id":"47c29025-cfa8-4447-9ab7-a229008ad088","IdentifierCode":"contractcarl","FirstName":"Carl","MiddleName":null,"MiddleNameHuman":"","LastName":"Smithers","DisplayName":"Carl Smithers","Email":"[email protected]","IsExternal":false,"UserTypeHuman":"Internal","CompanyId":"75bb05a4-1ec2-4042-aeba-a229008aca9f","CompanyName":"Entessa Pipeline & Terminal, MLP","CompanyIdentifierCode":"SHA","Password":"IWdH+qDIOucNrre6V4AgI6Exm2Vq5qkIdXdsWfP6jn4=","PasswordChanged":false,"ForceNewPasswordFlag":false,"Settings":[],"RoleGroups":[]}]}

我怀疑我错过了一些小东西,但是在查看了这个并尝试了各种可能的解决方法之后,我看不到它,所以我寻求一些帮助。 我想一旦我得到了从服务器返回小集合的数据,事情就会变得更简单。

提前致谢,

我最终找到了答案。 $v.KendoGrid 是一种包装 kendoGrid 调用本身的方法,其中某些内容正在被重置,以便当数据从服务器正确分页返回时不允许正确解析数据。

此后我重新处理了混乱的情况,以便我可以在 $v.KendoGrid 调用中为我的网格类型建立必要的参数。

感谢您的帮助,以及捕捉逗号的眼睛,布雷特。
