分析器错误消息: 未能加载文件或程序集“GrapeCity.ActiveAnalysis.Silverlight.Server”或它的某一个依赖项。系统找不到指定的文件。

我已经在引用里面加了，为什么还是没有？

第一次用这个。

你是自己新建的工程还是运行的ActiveAnalysis自带的例子呢
你运行ActiveAnalysis自带的Silverlight相关的例子时是否正常，比如：GrapeCity\ActiveAnalysis\Silverlight Samples

不好意思，是我犯错了，没有把引用设成本地复制

上面是我的代码，都是照着帮助文档里面弄的，但是报错，

服务器报错异常:invalid data source factory identifier,参数名:id

你参考的是帮助文档中哪一章节的代码呢

就是这章

多谢版主耐心回答

我按照该章节的提示新建了一个工程，可以正常运行，我建议你查看一下
D:\My Documents\GrapeCity\ActiveAnalysis\DataSources\NWind\NWind.mdb和
D:\My Documents\GrapeCity\ActiveAnalysis\DataSources\NWind\NwindMDB-SalesProductsSuppliers.schema的访问路径是否正确

多谢啊，终于出来了，问题出在ServerDataSourceManager.Register没有执行到，我将它放到Global.asax就可以了，我想问下，ServerDataSourceManager.Register是什么机制，是将querystring查询的结果放到服务器内存吗？如果我的报表很多会不会将服务器撑死？还是在客户请求数据源的时候再查询结果？请版主指教啊
