Grid Values when Column width is 0

FMX TMS FMX UI Pack
1

Hello,

When I Add columns to the grid with a width of 0. The values remain empty.

procedure InsertColumns(pBinding:TLinkGRidToDataSource);
  begin
    pBinding.Columns.beginupdate;
    try
      pBinding.Columns.insert(0);
      aCol:=pBinding.Columns[0];
      aCol.MemberName:='SOORTDOC';
      aCol.Header:='';
      aCol.Width:=0;
      pBinding.Columns.insert(1);
      aCol:=pBinding.Columns[1];
      aCol.MemberName:='DAGB';
      aCol.Header:='';
      aCol.Width:=0;
    finally
      pBinding.Columns.EndUpdate;
    end;
  end;

I use these values in other parts of my code. But since version 10.2 Tokyo these values are empty.

How can I read the values of these columns when the width is 0, or can I make them invisible?
When the width is 1, everything worksas exptected.

PS : Usecolumns := false
