c# - Sitecore - 使用渲染引用动态渲染 View / Controller 渲染

Question

我需要在不同的页面上动态呈现一个项目。 所以我检索了项目的渲染引用并使用渲染项目 ID 和数据源。

我可以渲染“ Controller 渲染”类型的项目，但不能渲染“ View 渲染”。

@Html.Sitecore().Rendering(renderingItem.RenderingID.Guid.ToString(), new  {DataSource = renderingItem.Settings.DataSource, Cacheable = false, Cache_VaryByData = false});

**Exception Message**: Attempt to retrieve context object of type 'System.Web.Mvc.ViewContext' from empty stack.

**Stack Trace**:   at Sitecore.Mvc.Common.ContextService.Peek[T]()
   at Sitecore.Mvc.Presentation.ViewRenderer.GetHtmlHelper()
   at Sitecore.Mvc.Presentation.ViewRenderer.Render(TextWriter writer)
   at Sitecore.Mvc.Pipelines.Response.RenderRendering.ExecuteRenderer.Render(Renderer renderer, TextWriter writer, RenderRenderingArgs args)

Answer 1

我最近在我的案例中遇到了同样的问题，我创建了一个自定义 MVC 路由，我需要在那里渲染 Item 的所有渲染。

我遇到了同样的问题， Controller 渲染正常但 View 渲染不工作所以我更改了代码来处理同样的问题。我添加了一个条件来检查呈现类型，并在此基础上添加了一些自定义代码来呈现这两种类型。

 if (rendering.RenderingItem.InnerItem["Path"] == null || string.IsNullOrEmpty(rendering.RenderingItem.InnerItem["Path"]))
            {
                PipelineService.Get().RunPipeline<RenderRenderingArgs>("mvc.renderRendering", new RenderRenderingArgs(rendering, writer));
            }
            else
            {
                ViewData.Model = rendering.Model;
                var viewResult = ViewEngines.Engines.FindPartialView(controllerContext, rendering.RenderingItem.InnerItem["Path"]);
                var viewContext = new ViewContext(controllerContext, viewResult.View,
                                             ViewData, TempData, writer);
                viewContext.ViewBag.renderingUniqueId = rendering.UniqueId;
                viewResult.View.Render(viewContext, writer);
            }

这个解决方案适合我。

可能它可以帮助某人并节省一些时间。
