Listbox Symbols


Recommended Posts

I'm going to try to summarize what your code is doing.  On value change it will read the number of items in your listbox then run a for loop that many times.  In that for loop you are setting the symbols each time, but the value doesn't change, and you are only setting one symbol, so you are turning off all the other symbols.  This is because the array size is always going to be 1.

 

If you want to set a symbol for every item, then you need to set the Symbols, with an array, whos size is the same as the number of items, right now the size of the array going into the Item Symbols property is always 1, so you are always going to only set one item to have a symbol.

 

Attached is a new version where on value change it creates an array of the same size as the number of items, and then sets the symbols for all items using that array.
