I have a Numeric Label bound to a tag and want to change the display format to only one decimal place.
I make the change from #,##0.## to #,##0.# and the label displays the correct format. When I save the project it reverts back to #,##0.## in the ‘Number Format Pattern’ property setting.
It sounds like the numeric label’s number format pattern property is bound. It is probably bound ta a tag’s number format attribute (this is set up automatically when you drop a tag onto a numberic label).
You cal tell when a property is bound because its name becomes bold in the property editor. You can either turn the binding off, or change the tag’s number format attribute that its bound to.
