Auto Checkbox: Only if All Children / Decedents are Checked

Anthony Barthelemy

Good Day All:

I am trying to modify a basic Formula to Auto Checkbox the Parent only if All the Children / Decedents are Checked.

=COUNTIFS(DESCENDANTS(), 1)

Thanks

Try something like this...

Choose another column that has data in each of the rows you are wanting to take into consideration. For example the Task Name column if you have a list of tasks...

=IF(COUNTIFS(DESCENDANTS(), 1) = COUNT(DESCENDANTS([Task Name]@row)), 1)

Basically what this does is counts how many descendants this other column has populated. Then it will compare the count of checkboxes to that count. When they equal each other, then all have been checked, and the formula will check your box.
