Select All as default value for Multivalue parameter

Question

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?

Answer 1

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.

Answer 2

Using dataset with default values is one way, but you must use query for Available values and for Default Values, if values are hard coded in Available values tab, then you must define default values as expressions. Pictures should explain everything

Create Parameter (if not automaticly created)

Define values - wrong way example

Define values - correct way example

Set default values - you must define all default values reflecting available values to make "Select All" by default, if you won't define all only those defined will be selected by default.
