ssrs-Pass Report parameter to DrillDown

Question

Im building a report, i make the GROUP BY in the SSRS (not in the DataSET), means that the group created in the SSRS,

now, how can i pass the values of the group to the Drill Down?

p.s - PseudoCOde: the DataSet (build in sql server 2008):

Alter....
Select
     ...Concat(x) MyX
     ,DocumentID
     ,Name
     ,Age
 Group BY DocumentID

---

In the SSRS my group is MyX, MyX - has the values of 'X' that grouped by DocumentID. now i want to pass the values of MyX to the DrillDown. how can i do it? thanks

Answer 1

I assume you have a parameter on the drilldown report to pass the value to. Then on the action that sends you to the drilldown set that parameter's value expression to be:

=Fields!MyX.Value
