Filtering EpiCombos

E9.05.702a/SQL2008R2


I'm trying to create a dashboard with a Tracker View used for searching/filtering.  I'm trying to use two comboboxes as search controls where combobox2 is filtered based on combobox1's selection.  Combobox1 and combobox2 are linked to the UD parent/child pair UD100 and UD100A, respectively.  I've tried all sorts of things based on examples from forums and training courses.  The struggle seems to be with this being a dashboard Tracker View and not a normal customization.  I wrote an event handler for EpiCombo.BeforeDropDown to update EpiCombo.SearchFilter with the value from the first combobox but I still get nothing in the dropdown list of that 2nd combo.  Yesterday it was throwing an exception but today it's just an empty combo.


Any suggestions would be greatly appreciated.


Thanks,
