May I ask you , if i need to create Check Box out of gallery for control checkbox in gallery as a details.

1. If checked on checkbox select all = all check box in gallery has been checked.

2. If Unchecked on checkbox select all = all check box in gallery has been Unchecked

On the OnCheck of the CheckBox Outside the Gallery: UpdateContext({SelectAll:!SelectAll})
On the OnUnCheck of the CheckBox Outside the Gallery: UpdateContext({SelectAll:!SelectAll})

Then on the Default of the CheckBox Inside the Gallery:  If(SelectAll,false,true)

Another Simple Approach:

You could also just on the Default of the CheckBox Inside the Gallery:  CheckBoxNameOutside.Value

I create a checkbox inside gallery when check box is checked will patch data to share point list ,

when I Checked one by one checkbox inside will patch to share point normally.

Your request had nothing to do with Patch. So am confused here.
