Question

我有一个MVC项目，我正在尝试添加Telerik报告。我能够设置报告并进行设计，但是当我创建报告查看器时，我收到了错误消息。我已经尝试添加对Telerik dll的引用，将dll添加到bin中，为web.conifg添加了各种选项，但没有任何效果。你能帮我搞定一下吗？

创建报告后，我使用报告查看器向导添加了一个包含报告查看器的视图。我添加了一个新项目“Telerik MVC Report Viewer Page Q2 2015”，如下所述：http://www.telerik.com/help/reporting/mvc-report-viewer-extension-embedding.html

这创建了一个名为ReportViewerView1.cshtml的视图。问题是当我运行网站时，我在@（Html.TelerikReporting（）。ReportViewer（）上写错误

CS1061：'System.Web.Mvc.HtmlHelper'不包含 'TelerikReporting'的定义，没有扩展方法 'TelerikReporting'接受第一个类型的参数可以找到'System.Web.Mvc.HtmlHelper'（你错过了吗？使用指令或程序集引用？）

我尝试添加对各种dll的引用但没有成功。我找到了http://www.telerik.com/blogs/using-the-telerik-extensions-in-asp-net-mvc4-today---a-first-look和http://www.telerik.com/blogs/telerik-reporting-in-mvc-sure-it-takes-8-quick-steps-但是他们的步骤也没有用。我有一个使用报告查看器的旧asp.net（不是MVC）的同事，我复制了他的web.config元素，但这也没有帮助。

以下是报告查看器的视图：

@using ProjectName.Views
@{
ViewBag.Title = "Telerik MVC HTML5 Report Viewer";

Answer 1

遇到同样的麻烦，我不得不将以下内容添加到剃须刀页面的顶部：

@using Telerik.ReportViewer.Mvc
@using Telerik.Reporting

我还将报告从MVC项目的根目录移到了views文件夹中 - 不确定这是否有帮助。

Answer 2

如果您希望Razor识别Telerik命令，那么您应该将库引用添加到位于Views目录中的Web.config文件中（而不是主Web.config文件！）。

在这个文件中会有一个<system.web.webPages.razor>部分 - 需要在这里添加命名空间，以便Razor可以使用它们：

<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
  <namespaces>
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Optimization"/>
    <add namespace="System.Web.Routing" />
    <add namespace="Telerik.Reporting" />
    <add namespace="Telerik.ReportViewer.Mvc" />
  </namespaces>
</pages>

Answer 3

您要查找的扩展方法位于short lib。添加对它的引用，不要忘记使用：

Telerik.ReportViewer.Mvc.dll

Answer 4

我也有类似的问题，但我的更多与@RenderSections有关。如果你有部分telerikReportViewer控件，请确保将@section样式和@section脚本放在调用partial的父页面上。
