David,

Thanks a lot, it was really helpful. Using GanttSeries, GanttItem and GrantTimeEntry  classes it was really easy.

I got 2 more doubt. I made a GanttSeries and in that added different GanttItem and in each GanttItem I made different GanttTimeEntry which made the Gantt Chart ready. Now my doubts 

1) In each bar I need to give a specific label and a specific tooltip too. I tried to put a label this way

ganttTimeEntry.Label = "jebinjc";

but nothing worked and about tooltip I didnt find any help.

2) Is there a property to group the dates which is in X2 axis or how can I do something like below

                  2/12/2009                                        2/19/2009                                               2/26/2009       

Sun Mon Tue Wed Thr Fri Sat       Sun Mon Tue Wed Thr Fri Sat             Sun Mon Tue Wed Thr Fri Sat

and so on......

Looking forward for your reply. Thanks in advance

Is there any way to display the task owner on the tooltip? I read the about the IRenderLabel class implementation but I still can't understand it very well

Thanks

Misael
