主要问题是您试图在Web应用程序中启动Winform应用程序.因此，即使弹出报表设计器，它也会在您要求的计算机上而不是客户端计算机上弹出.

***是创建一个clickonce应用程序，然后从那里运行它.

我假设您正在使用开发人员快速报告.

还研究了他们有关如何将报告存储在自定义存储上的文章，因为您将不得不通过使用Web服务将报告解析回服务器.

The main problem with this is that you are attempting to launch a winform app in a web application . so even if the report designer pops up it will pop up on the server machine and not the client machine as you requuire it to.

best would be to create a clickonce application and running it from there.

I assume you are using developer express reports.

also research their article on how to store reports on custom storage becuase you will have to parse your reports back to the server via the use of web services.
