Hello Hristo,
Thank you for your quick answer.
Here is the details my boss would like to see:
I'd like to display null date data in the ganttview without changing start or end date of it
My data have many record without start or end date, and I'd like to see all of them in the ganttview. The ganttview have two part, text and graphic, in the text, if start or end date is null, I'd see that field is empty like gridview. In graphic, I'd like see nothing in the grapphic for records whose start or end date is null.
Thanks & Regards
