Hi,

I was trying hard to use Gantt with Oracle Database over the Oracle Managed Connection, with Visual Studio 2013/ASP.NET 4.5. Well I had a few problems.

Then I returned to the blackboard and Worked on your Example. Then I hit an end.

So when you want resource assignments to be made, You cant. The events do not trigger. Am I missing something?

Then I kind of added some to simulate my own project.

Same problem.  Assignment events are not firing (e.g. RadGantt1_AssignmentInsert)

Hello All,

We are aware of that problem and it is a bug, related with the RadGantt server-side event triggered. Here you can vote for the bug fix and track it's status, in addition, I have increased the bug priority.

http://feedback.telerik.com/Project/108/Feedback/Details/175854-radgantts-server-events-for-assignments-update-insert-and-delete-are-not-trig

On a side note, as a workaround, you can use a CustomProvider for the Gantt data population.
