Paint a column in a listbox

[philm]

Hello everybody,

The aim of the sub-vi attached is to paint in yellow the firts column of a multicolumn listbox.

My problem is when the number of rows is greather than 2000. The execution is very, very, very slow (60 seconds for 3500 rows for example) !! It is not acceptable for the users.

Has somebody an idea to improve that ? The idea is to avoid to use a loop of course, but i don't have any idea ...

Many thanks for your help,

philm.

You need to use -2 for the Row. It also helps to use DeferPanelUpdates.
