Lock Text of a Combo Box Control

[Taffarel]

I'm using a combo box to select options. When the program are running, the user can write at the combo box field. I tried to disable it but then the option can't be selected.

Is there a way to lock the text field to the user only select the options that i created for combo box?

thanks for help.

Right-click the combo box and uncheck "Allow undefined strings." This will stop the user from entering in his own string.

I'm doind this, but the user still can edit the field, i want a way like a disable mode, where the user can't write.

Ring it's a exit, but only accept a numeric value and i need use a string in a value

I have several combo boxes set up like this, and I just made an example to double check. When "Allow Undefined Strings" is unchecked, the user cannot enter his own string. I don't know what you're doing differently than me, but it works fine when I do it.

The only thing that can be done is deleting what is already in the box, but you cannot type your own string. What version of LabVIEW are you using?

OK, here's another idea if you don't want the user to be able to even select the text in the combo box. Make it an enum, then send it to format into string with %s as the format string. The output of this will be the string that was selected from the enum.

Yeah, the problem is that you can delete the string. But this is the better way that i can made. Thanks for help
