Now we have "OnRecordSelect" that fires if only one record is selected. Really it doesn't fire when selecting one record but when "Total record count"=1. Try this: Select 1º= it fires, Select 2º=nothing, Deselect 1º= it fires. It should actually be called "OneRecordSelected"

If we could control when the number of selected records changes, we could show/hide information on the form that would be appropriate for the selection made by the user (and only then). In this new event, and with the help of "getSelectedRows" we would know how many and which have been selected.
