Logic/Toggle Question

I am trying to do the following (without using a parameter box to drive the results)



I would like to be able to toggle the results instead of using a parameter.



The default view for the table data is any row that meets a threshold criteria (similar to a KPI)

I would then like for all of the data to be exposed when toggled which eliminates using IIF (unless I am missing something).

I would think that if I could reference the toggleState of a textbox I could do this (similar to a yes/no Show All parameter), but I found little to nothing on how to do this within Reporting Services.

I guess I could also use two datasets to achieve this, but I would prefer a more elegant result.
