Hello Tiago,
Thanks for the reply. There are all kinds of custom made pieces built in for the customer, most of it before I took over the development of this app... We're trying to find out if the ListBox method is really needed, but knowing the customer, this very well could be the case.
I've suggested to use the MultiRange method, which still works. If the customer chooses to decline this proposal, we probably have to go back to an older version of the datagrid. Thanks for the help so far!
Regards,
Sven
