ReportViewer控件中的筛选器（使用AS Cubes的报表服务）

I have created a report with SQL reporting services and used Analysis services Cubes as a datasource. I also defined some filters at the time of report design. When I use reportserver to view report, all works fine, report displays based on the filters selected also. Now I used ReportViewer control to view the report on my application. I set ReportServerUrl, ReportPath and used ReportServerCredentials for authorization. When I executed my aspx screen it displayed me report correctly but the filter was not working. Every time I changed filter values and clicked on ViewReport button, it automatically resets the filter values.I have created a report with SQL reporting serv
