Question

我已按照本文档link中的说明操作。 xtrareport显示框工具栏但不显示任何数据。我做错了什么？

在我的HomeController.cs

中

 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

尝试更改DocumentViewerPartial.cs ViewData["Reports"]与ViewData["Report"]

。{

Answer 2

在XtraReport1中你怎么写？如果你提供你的代码XtraReport1或者为我们提供一个简单的案例演示，那就太好了。我在你的控制器中看到，如果你写这个，它会得到第三个数据： ViewData [“Report”] = new DXApplication.Reports.XtraReport1（）;

Index（）
DocumentViewerPartial（）
ExportDocumentViewer（）中的第三个

准备好你只需要获取数据第一，你可以写：

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()

然后在文件Index.cshtml中最后调用：

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

请执行相应的修改，并告诉我您的结果。

XtraReport没有显示任何数据
