Gray Checkbox but is still Editable

[JordanBillingsley]

Ocassionaly I will find a checkbox that has been grayed out but is still editable.

I just want to understand this behavior better. It can be confusing in the midst of troubleshooting an issue.

Thanks! - worst case scenario is that I waste a few minutes second guessing myself

can you post an example?

Thanks Sector, I edited the original post to include a short screen cast

I wish I could see it.

Now it's clear. That scenario happends if your family type A and type B are both selected in the project but that checkbox (yes/no) parameter have different validation (checked) for each one : A is checked and B is not. If for both are checked or unchecked there will be consistency even in terms of that parameter.

Ah yes I have experienced that before but that doesn't quite seem to be the case here. In this second clip I show that I have just one sheet selected.

Thanks for taking a stab at this, its normally something I ignore but today I managed to catch myself in the action

I think it might have to do with it being a Project Parameter

When just one item is selected, a grayed but editable checkbox indicates that a choice has not yet been made for that parameter for the selected item.  Once you click on the checkbox, it should be full intensity and remain that way, whether you leave it checked or unchecked.

Thanks David!

Doesn't that seem a little confusing for the end user? Grayed out fields usually indicate that the item is not editable and someone will give up trying to solve their problem.

Thanks again,

@David_W_Koch is spot on. It's the old "null condition". Neither 1 or 0. No value whatsoever. If you were to add a calculated parameter to a schedule that reference its condition, that value would return a blank. For instance: if you to write a TEXT calculated parameter that had the if statement: if(Exclude from Sheet Count, "Yes", "No"), you would expect it to return a "Yes" or  a "No", but instead it returns nothing if "Exclude from Sheet Count" parameter is grayed out (inactive).
