I do not understand what you mean by "enable". There is no enabling of a formfield checkbox. Once you protect the document for forms, it is a single click to toggle it checked, or unchecked.
If it is unchecked, a single click checks it.
If it is checked, a single click unchecks it.
Now, are you asking about enabling through:
1. a right click
2. Properties
3. uncheck (or check) "Check box enabled"
Is this the three clicks you mention? If so, please say so. Also...why are you doing this? Especially as " we want to be enable one checkbox at the time".
WHY? If you really do want to do it one at a time, then...that is what you have to do. One at a time. Plus, the document has to be unprotected for forms in order to do this.
Could you please clarify the "we"? The user?
Have you tried recording a macro? You
could have a wee macro that uses a shortcut key to fire.
Code:
Sub DisableCheckbox()
' shortcut key = Alt-e
Selection.FormFields(1).Enabled = False
End Sub
This would make the current selected formfield disabled. However, it also retains the current state. If it
IS checked, it would remain checked, but disabled. If it was unchecked, it would remain unchecked, but disabled.
It may help if you state what it is you are trying to do.
