I'm building a report in Visual Studio 2008 with a lot of multivalue parameters and it's working great, but I would like to have have the "(Select all)" option as the default value when the report is opened.
Is there some kind of expression or SQL code I can use to make this happen? Or do I need to choose "(Select all)" every time, in every parameter, each time I want to run the report?
Try setting the parameters' "default value" to use the same query as the "available values". In effect it provides every single "available value" as a "default value" and the "Select All" option is automatically checked.
