0 Documentation/Samples for Adding a new Data Filter? 2 David Leigh posted 9 Years Ago I am looking to create a new Data Filter, and I would like to know if there are any guides to doing this. I would like to implement this filter (and others) in a separate custom assembly and export it in a way that I can drop it in and Rock will show it in the list of available filters. I'm currently looking at the existing Data Filter implementations, but is there any other guidance on best practice for implementing custom Data Filters?
