Hi experts,
I have a selectionable table and I need to compare the selections, ie: I select one row and my program selects also others rows of my table that has the same 'number EM' (it is a column of my table). When I unmark a row of my table, automatically I have to deselect all the rows that have the same 'number EM'. Is there a method that I can to use for to know when a user has deselected this row? Or is possible to store the precedent selection, so I can to compare?
Tks a lot.
