Well, as suggested by Kevon earlier in this thread, I separated out the filter functionality from my HouseGlossary module and put it into a module of its own, HouseFilter. This new module simply displays a filter and uses inter-module communication to send the selected value to any listening modules.
I built in options for displaying pure alphabetic and alphanumeric filters, but it can also accept a comma-separated string of custom filter options (e.g., categories). You can choose to display it as either a series of LinkButtons or a DropDown.
Find out more at the House of Nuke site, and download it for free. Both PA-only and full-source versions are available under the same open source license as DotNetNuke.
There's also an updated version of HouseGlossary, now using the HouseFilter module for its filtering needs.
Please let me know what you thnk or if you spot any issues. Thanks!
