Hi,

I tried to build my first gant chart using DB but could not work it out since after loading data NextTask alwyas mixed up.

I use the following sql statement to populate data:
Create Table #GantTest
(
Start DateTime,
Y int,
[End] DateTime,
NextTask int
)
Insert #GantTest Values('01/01/2006', 1, '01/10/2006', 3)
Insert #GantTest Values('01/05/2006', 2, '02/10/2006', -1)
Insert #GantTest Values('01/15/2006', 3, '01/20/2006', 4)
Insert #GantTest Values('01/21/2006', 4, '01/31/2006', 6)
Insert #GantTest Values('01/15/2006', 5, '01/17/2006', 6)
Insert #GantTest Values('02/01/2006', 6, '03/01/2006', -1)
Select * from #GantTest
Drop Table #GantTest

Any help will be much appreciated.

Thanks,
Doug

Hi Doug,

We would need some more information on how your project uses the series to be able to help you. Could you please send us a simple example project we can run "as-is" to reproduce the problem here? Could you also let us know which TeeChart version are you using?

You can post your files at news://www.steema.net/steema.public.attachments newsgroup.

Thanks in advance.

Hi Narcis,

I think I found what the problem is - please confirm

Regardles of nextask value returned by my query GanttSeries will initially set NextTask property to -1. In order to set proper NextTask I need to do that programmatically. like in your example:
GanttSeries1.NextTask[ tmp1 ]:= tmp2 ;

Please confirm my theory

Cheers,
Doug

Hi Doug,

Yes, you are right, you need to assign NextTask programmatically as you said.
