ReportViewer控件不显示报告 [英] ReportViewer control not displaying reports

问题描述

我到处都在寻找解决此问题的方法，但尚未找到对我有用的方法.我在托管服务器上设置了报告服务器(2008 R2).我已经使用报告生成器从头开始创建了一个报告，并在使用URL登录到报告服务器时对其进行了测试，并成功生成了报告.

I have looked just about everywhere for a solution to this issue and have not found one that has worked for me yet. I have a reporting server (2008 R2) set up on our hosting server. I have created a report from scratch using the report builder, tested it out while logging into the report server with its URL and it successfully generates reports.

当我尝试从MVC应用程序查看报告时，仅呈现报告工具栏(显示导出，打印，页面和查看报告"按钮).它表明它是正在加载"，完成后它只是一个空白报告，但它在工具栏上显示了正确的参数，如果我更改了代码中的参数名称，它将返回错误，说明该参数没有不存在所以我知道地址用户/密码信息是正确的.

When I try to view the report from our MVC application, only the reports toolbar renders (showing export, print, pages, and the view report button). It shows that it is "Loading", and after it completes it's just a blank report, but it shows the correct parameters on the toolbar, and if I change the name of the parameters in the code it returns an error stating the parameter doesn't exist; so I know the address user/pw information is correct.

推荐答案

我终于使它起作用了.对于那些与我有相同问题的人，这是我为使其正常工作所要做的.

I finally got it to work. For those having the same issues as me, this is what I did to get it to work.

在页面指令中，设置 EnableEventValidation ="false" ，并为报表控件设置 AsyncRendering ="false" .

In the page directive, set EnableEventValidation="false" and for the report control set AsyncRendering="false".
