XtraReport没有显示任何数据

Question

我遵循了本文档链接中的说明。xtrareport显示框工具栏，但不显示任何数据。我做错了什么？

In my HomeController.cs

 public ActionResult Index()
        {
            ViewBag.Message = "Welcome to DevExpress Extensions for ASP.NET MVC!";
            ViewData["Report"] = new DXApplication.Reports.XtraReport1();

            return View();
        }

       public ActionResult DocumentViewerPartial() 
       {
        ViewData["Report"] = new DXApplication.Reports.XtraReport1();
        return PartialView("DocumentViewerPartial");
        }



        public ActionResult ExportDocumentViewer()
        {
            return DevExpress.Web.Mvc.DocumentViewerExtension.ExportTo(new DXApplication.Reports.XtraReport1());
        }

DocumentViewerPartial.cs

**@Html.DevExpress().DocumentViewer(settings =>
{
    settings.Name = "DocumentViewer";
    settings.Report = (DXApplication.Reports.XtraReport1)ViewData["Reports"];

    settings.CallbackRouteValues = new { Controller = "Home", Action = "DocumentViewerPartial" };
    settings.ExportRouteValues = new { Controller = "Home", Action = "ExportDocumentViewer" };
}).GetHtml()**

和Index.cshtml

{
    ViewBag.Title = "Home Page";

}
@ViewBag.Message

@Html.Action("DocumentViewerPartial")

Answer 1

通过使用DocumentViewerPartial.cs ViewData["Reports"]更改ViewData["Report"]来尝试

Answer 2

在XtraReport1里你是怎么写的？如果您提供您的代码XtraReport1或向我们提供一个简单的用案例演示的示例，那就太好了。我在你的控制器中看到了，如果你写的话，它会得到数据第三:ViewData“报告”=新的DXApplication.Reports.XtraReport1()；

1. 索引()中的第一个
2. DocumentViewerPartial()中的第二个
3. ExportDocumentViewer()中的第三个

准备好了，您只需要第一次获得数据，您可以写：

public ActionResult Index()
    {
        ViewBag.Message = "Welcome to DevExpress Extensions for ASP.NET MVC!";
        return View();
    }

   public ActionResult DocumentViewerPartial() 
   {
    Session["Report"] = new DXApplication.Reports.XtraReport1();
    return PartialView("DocumentViewerPartial");
    }

    public ActionResult ExportDocumentViewer()
    {
        return DevExpress.Web.Mvc.DocumentViewerExtension.ExportTo(Session["Report"] as XtraReport1());
    }

在DocumentViewerPartial.cs中，您可以编辑：

@Html.DevExpress().DocumentViewer(settings =>{
settings.Name = "DocumentViewer";
settings.Report = (DXApplication.Reports.XtraReport1)Session["Reports"];

settings.CallbackRouteValues = new { Controller = "Home", Action = "DocumentViewerPartial" };
settings.ExportRouteValues = new { Controller = "Home", Action = "ExportDocumentViewer" };}).GetHtml()

然后在您调用的Index.cshtml文件中完成以下操作：

@Html.Partial("ExportDocumentViewer")
@Html.Partial("DocumentViewerPartial")

请执行相应的修改，并让我知道您的结果。
