I've seen websites explain how to use a tablix to list possible parameters for a report (another tablix) to simulate slicers. This technique relies on passing parameters and the report being refreshed.
The issue is, this is slow for where I want to use it. I am wondering if there is a way to load all the data for my report and then use a similar technique to create a slicer to limit the data using the filter on the dataset.
Another option I thought about was simply hiding the rows that didn't match what was selected in the "slicer".
