Hi all,

How do you set up a checkbox so that only one value is set such that selecting another value will clear the current value.

First, you should format the field as a radio button set. Checkboxes are intended for multiple selections.

However, since even radio buttons allow multiple choices to be selected by holding the Shift key, make the field auto-enter calculated value (replacing existing value) =

RightValues ( Self ; 1 )

 

Thank you comment, perfect

Comment, that will include a return in the field. Wouldn't it be better to use getValue ( self; 1) ?

Or

getValue ( self ; valuecount( self))

Yes, it will. I am not sure it will cause any problems, but it is certainly worth mentioning.

That wouldn't allow selecting another value.

 

Thank you for the information BruceR and having checked, as comment said, the return does not present a problem that I can see.

Not sure what that means.  You would have to discuss how you use this field in perhaps reports or other operations or perhaps in merge layouts, etc. Or for instance, Find operations, where an exact match search would fail because the field contains a return.
