Reporting Services 2008:
I've a report with 3 columns. What I like to do is to toggle the visibility from the columns based on a parameter. Parameter Value can be C1, C2, C3, ALL.
Showing only 1 column is posible with an expression for Column visibility =NOT(Parameters!P_Dienst.Value="C1") (or C2, or C3)
But what I like is "ALL Columns" or "C1" (or C2, or C3)
I've tried =NOT(Parameters!P_Dienst.Value="C1") or =NOT(Parameters!P_Dienst.Value="ALL"), but this results in no data.
Anybody an idea how to solve this?
