在ASP.NET MVC中渲染局部视图
我的代码如下。当我运行代码时，我可以看到ViewBag变量中的所有数据。但是在浏览器上渲染时，我看到了空白页面。可能是什么原因？代码有什么问题吗？请帮我。谢谢。
//控制器代码
public class BlockController : Controller
{
[Authorize]
[HttpGet]
public ActionResult Index()
{
BlockViewModel model = new BlockViewModel();
ViewBag.Facilities = new List<FieldProcessingFacility>();
ViewBag.Data = new List<BlockField>();
ViewBag.BlockFields = new List<BlockField>();
ViewBag.Tanks = new List<FacilityTank>();
ViewBag.Facility = new List<FieldProcessingFacility>();
ViewBag.Blocks = model.GetAllBlocks();
ViewBag.BlockPartial = new Epsa.Client.ViewModel.Master.Blocks.BlockViewModel();
ViewBag.BlockField = new Epsa.Client.ViewModel.Master.Blocks.BlockViewModel();
ViewBag.BlockFacility = new Epsa.Client.ViewModel.Master.Blocks.BlockFacilityViewModel();
ViewBag.BlockTanks = new Epsa.Client.ViewModel.Master.Blocks.BlockTanksViewModel();
return View(model);
}
[HttpPost]
public PartialViewResult GetDetailsOfBlock(long blockID)
{
// To get fields
BlockFacilityViewModel bkvm = new BlockFacilityViewModel();
var fields = bkvm.BlockFieldList(blockID);
ViewBag.Data = fields;
// To get facilities
BlockViewModel bvm = new BlockViewModel();
var facilities = bvm.GetFacilitiesByBlock(blockID);
ViewBag.Facility = facilities;
// To get Tanks
BlockViewModel blockModel = new BlockViewModel();
var fieldtanks = blockModel.GetTanksByBlockID(blockID);
ViewBag.Tanks = fieldtanks;
BlockSingleViewModel blockSingleModel = new BlockSingleViewModel();
ViewBag.Types = blockSingleModel.GetBlockTypes();
//return RedirectToAction("Index");
return PartialView("_PartialBlock");
}
}
//我的部分视图

- 您必须使用
PartialView类型参数调用BlockViewModel函数。在这个时候你的部分参数显示为空。
return PartialView("_PartialBlock",blockModel);
