I try to write an event on "DBGrid-OnDrawColumnCell",
and it caused an error of "External:SIGSEGV",
when I use like,
"if COlumn.Field.DisplayName='CHIKU' then",
"if Column.Field.FieldName='CustNo' then" or
"if Column.FieldName='CHIKU' then".
When I use "if DataCol=1 then" is OK.
But these 4 lines are OK in delphi6.
anybody, any idea?

Just check if Assigned(Column) and Assigned(Column.Field) ?

Thank you for your reply!
I just put "if Assigned(Column) then" before asking
"if Column.FieldName='CustNo' then", and
it works! Thanks!
