I am using SSRS 2008. I have 2 parametres. programs and Sites. Both parameters are multi value parameters. Sites parameter depends on Program parameter. By default when the report is opened program and Sites parameters are all selected. When program parameter is changed i am loosing selecting all option. It is not refreshing the selection. I can see parameter values for sites but it is not selectingall values Is there any problem with this 2008 version Thanks
