Simon,
Actually in documents it states 255 for max len literal strings (Capacities). Here with 240 chars I don't think it's char limit but an error in expression. Probably you wrote it right for your method. What happens if you put the controlsource in grid init like this :

This.myColumnx.Controlsource = ;
[(ThisForm.LongDate(AMSched.Date)+" "+]+;
[ThisForm.GetTime(AMSched.Time)+]+;
[" "+ThisForm.dCSeek(AMSched.Sport,"AMActvty","ID","AMActvty.Desc")+" "+]+;
[ThisForm.dCSeek(AMSched.Opponent1,"AMMaster","ID","AMMaster.Id1")+" vs "+]+;
[ThisForm.dCSeek(AMSched.Opponent2,"AMMaster","ID","AMMaster.Id1"))]

However, I do know that if I put a long expression (240 Characters) in the controlsource nothing will be displayed in the grid and no error message will be given. Should this be considered a bug?
