Ok here is an example, I have a gallery, and in it I place a checkbox and set it's Text to "AC Ducts".

I then set it's Default to

If(Self.Text in ThisItem.Area.Value, true, false)

where Area is the choice column, and .Value are the choices selected in it.

Any item that has AC Ducts chosen will be checked and those that do not, will not be checked.

This method can be used to set default for them so they can be pulled back up later and edited etc

@TheRobRush
Here, see the image. Have one Gallery which have one checkbox control. Gallery item property is Choices([Project].Answer'). I'm saving this choice feild values in Project List. Now I want to display the same in other screen in displayMode as View and also wants to pre check the checkboxes based on saved choice values.
Currently, I'm able to show the selected values in lable or text but i want to show in same manner in gallery checkbox control. Like the save choice values will appear as pre checked and others not.

You will need to show us what the column you in sharepoints details are for the column you want to be default for your checkbox. And then explain what data you want saved there, and how you want checkbox to react to it. (true false, based on a word, etc.)

yes you can, but we will need more info on the structure of your gallery, list, and what controls/values the checkbox default values will be based on
