Hi
Use the Positioning tool to select the entire Multicolumn Listbox. Then use the Text Settings in the LabVIEW toolbar to change the font, style and so on. You will see that the font of all the items in your Multicolumn Listbox (including its label) are changed at once.
If you want to change only one item, than you can use the Text tool.
