Restoring the tree list from an empty or corrupted store using RestoreFrom~ method calls assigns incorrect Column.Position.BandIndex property values, and as a result, hides these columns

Hello.I'm using a TcxDBTreeList. I need load settings from ini storage, when file doesn't exist all column hide. What am I doing wrong?

    Hello,
    I suggest that you use the following code:

    Delphi
    if FileExists(ChangeFileExt(ParamStr(0),'.ini')) then  
  TreeListMain.RestoreFromIniFile(ChangeFileExt(ParamStr(0),'.ini'), False, False, TreeListMain.Name);

    It should solve the problem.

        If I have two TcxDBTreeList (In different forms) and one settings file.

        1. Open first form (file don't exist) all right. Close form and save settings (file was created).
        2. Open second form (file exist, but settings section don't exist) and we have problem again

          It seems that there is no easy way to load layouts in this case except by creating separate files for each TreeList. I have forwarded this ticket to our developers for research. Perhaps, we will be able to find a solution (this may require some time).
