The app runs fine except that I had to change my references to \syncfusion evaluation\ since I''m using the eval version (2.1.0.10) for the dll''s. I do however always get a System.IndexOutOfRangeException when I run any project with your grid. I''m using Delphi 8 Enterprise (Upgrade 2).
Included find a project that sometimes causes the AV. Try rebuilding it several times and running it. Also try saving the project as Project1, Project 2. Currently I reboot my PC and get the AV after about by 2nd rebuild. This seems to vary however but does appear at some stage. Once you start getting the AV it seems to hang around forever.
