    Because TGroupBox inherited from TWinControl , it has the Controls property - an array of all controls that lies inside it. In the loop, loop through everything (indexes from 0 to ControlCount -1) and change Enabled

    PS The Enabled property is missing from components ( TComponent ). It appears only in controls ( TControl )

    • var I, K, x: Integer; ChildGroupBox, ChildControl: TControl; begin for i: = 0 to ComponentCount - 1 begin begin If Components [i] is TGroupBox then for k: = 0 to ControlCount - 1 do begin ChildControl: = Controls [k]; if ChildControl.Name = 'gbHeader' then for x: = 0 to gbHeader.ControlCount -1 do begin ChildGroupBox: = gbHeader.Controls [x]; ChildGroupBox.Enabled: = True; end; end; end; end; - djoni
    • I have one question left if ChildControl.Name = 'gbHeader' then for x := 0 to gbHeader.ControlCount -1 do in the cycle itself I indicated the object itself. What type should I declare to be able to use a variable instead of an object name? for example _VariableName.ControlCount -1 - djoni

      But I can not understand why you are looking for, ChildControl. Name = 'gbHeader', if you already have gbHeader? - German Borisov
    • one
      The fact is that I have 4 GroupBoxs on my frame, and in some GroupBox not all controls need to be made active. - djoni
