XtraReport.ShowPerview()报"The method or operation is not supported"的错误
我的DXperience工具是11.1.8的，已经破解了，我是用Winform的Report Designer设计的repx文件，我用的开发工具是VS2010，然后在Asp.Net的页面后台加载这个文件，用XtraReport控件显示报表，但是每当程序运行到XtraReport的ShowPerview方法时都会报"The method or operation is not supported"的错误，刚开始遇到这个错误时，我以为是我少添加了引用，我就根据Devexpress的帮助文档http://documentation.devexpress.com/#XtraReports/CustomDocument9367添加了这些引用，但是任然报这个错；于是我就在其他本版的DXperience(10.1.5)环境下做测试，也是报这个错。下面是我用VS2010写的一个demo：
