My application has been working fine on Delphi 10.3. However, it failed to compile when using Delphi 12.0 because of undeclared TNavButton. I did a comparison of a file vcl.DBCtrls.pas between Delphi 10.3 and 12.0 and noticed TNavButton is no longer in Delphi 12.0. Has anyone experienced this issue? Any solution would be appreciated. Thanks.

For displaying the image after retrieving it from the database I use another TImage component.

I’ve faced this and even found some answers about the same issue on C# but nothing delphi related:
