I had written a small proof of concept of building a gantt (like) chart using Advanced DataGrid component that shipped with Flex 3. The blog post with the source code happens to be one of the most popular posts in my blog. Folks keep writing to me asking for more details on the component. I haven’t really been able to keep that project alive, purely for want of time as I got busy traveling. Just yesterday, I was doing some Flex 4 hacking for my talk at the upcoming Adobe Flash Platform Summit in Bangalore and thought if I could re-write this component in Flex 4. I spent about 6 hours writing this and I got my first version of the Flex 4 gantt chart working. Doing this in Flex 4 is insanely easy and the folks at Ilog have done a fabulous job re writing their gantt chart component in Flex 4. Click here or on the screen shot to see a small demo. Please note that the demo is view source enabled, you can download the source code as well [Just right click on the demo and view source] or, just click here to view source
This is just a prototype and doesn’t handle all the cases that a standard gantt chart should be handling. I would strongly recommend testing the code thoroughly before you start using it in production (if you are planning to, that is) I am unsure how much time I will be able to spend taking this project forward. I have opensourced this one under MPL, feel free to take the code and do more stuff as you guys deem appropriate. Please note that this is a resultant of a few hours of careless hacking , I am sure this has a lot of bugs too. I plan to set up a GitHub project for the same, just thought I’d post it anyways.

Hi Harish,
good job! Sounds good to have a free Gantt Chart Component in the future! (maybe part of future Flex SDK’s)
Any updates? Did you set up a GitHub or Google Code project?
Would be nice to hear from you.
