I am trying to have a number display with a thousand seperator, but want the decimal places as auto...only displaying when a user chooses to type them in, but can't see how to change it without changing control panel settings. Help please!
Using the settings for the control, change Format to Standard and leave Decimal Places as Auto. Or, are you trying to override the Regional Settings? If so then you will have to force the format like Pbaldy is suggesting.
