I have 5 fixed parameters in my report that I pass through from VS 2008. One of them is a company Id. What I want to do is filter a parameters data according to the value of the companyID? How is this even possible. I got a test report working where it filters the data displayed on the report by the companyID passed through. But as soon as I use that data as a parameter for other purposes it doesnt display anything in the parameter box, and I have to enter the ID's and this I cant do as my ID's are unique identifiers. Or at one point I get all the data in the table but it's not filtered according to the CompanyID. Any Ideas please. I have tried cascading parameters, but although when I send a value through it keeps on asking me to select a companyID. PLEASE HELP!!! Will be greatly appreciated.
