Conditionally disable a Checkbox

skellie

How do you conditionally disable a checkbox. The form asks about sports. The condition goes like this:
If the user ticks the 'mountaineering' checkbox then if the 'none' checkbox has been ticked then remove the 'none' selection and disable the 'none' checkbox so that it cannot be selected.

I have tried the Protect and Read Protect actions but they cant get down to the level of the attribute values. Seems they protect attributes only.

Thanks

Hi Skellie,
I´m not sure what type of checkbox you are refering to? Is it a "Yes/No" attribute or a "Plain text" attribute with the checkbox activated in queries (each row)?

If it is a "Yes/No" attribute, you can use the protection rules to achieve what you´re after. Here are a couple of example rules for your scenario and you would have to make these rules form dynamic i.e. the rules has to fire dynamically on the form. You would also have to set the "Yes/No" attributes so they save when a value is changed:

If BO.Mountaineering WAS CHANGED TO "Yes" Then
BO.None='No'

If BO.None='No'
PROTECT BO.None FROM ALL Except System

The problem if you will with this solution is that you would not be able to select the BO.None flag if it´s set to 'No' (you would have to for example change it back to 'Yes' via rules if all other checkboxes are set to 'No' etc., you get the idea).

Thanks Hendrik
It is a plain text attribute with choices presented as check boxes, eg scuba, mountaineering, sky diving, other, none. So user can choose one or more sports, or none. So just trying to control which checkboxes are enabled. If user chooses a sport then he cannot tick none, and vice versa.

OK am going to change the attributes to yes/no, see if I can get it working.

Yes the yes/no solution should work but a tip is to think a couple of steps ahead because as things change and your choices change your configuration has to change and some configurations are harder to change after a live publish than others.
