i have a top categorie and a subcategorie in two listboxes.
like: click in top categorie (listbox1) -> open sub categorie (listbox2)
if i click on the first listbox the categorie, the second listbox swtich into the subcategorie. but i did not work! there is only one top categorie marked, but i cant change it! What can i do to change it?
if i copy all the code into a new file, it all works fine, but not in my actually. i dont now why.
my soltution that did not work:
a) in properties: only one value is not marked
b) the formel for the field is: =[~appDim2.Kategorie]&'/'&[~appDim2.SubKategorie]
("/" is for the tree strukture)
c) can't unmark the actually marked fieldname in listbox
