We just started using your GanttView and we have a requirement to have multiple events or "GanttTasks" on a single line. It appears that whenever I add a GanttTask or child to a GanttTask, it always creates a new line item for the task. Is there anyway to represent multiple events or tasks on a single line?

Thank you for your interest in our RadGanttView control.
This feature will be supported in the official Q2 2012 release. Hope this works for you.
All the best,
the Telerik team
Our schedule have changed slightly and we couldn't complete the feature for 2012 Q2 release and we will do our best to do it for the 2012 Q3 release, but for I cannot give you certain time frame for releasing the feature.

What's the latest status on this request? We are currently evaluating Gantt controls and this is one of our requirements.
we are about to buy a product for Gantt charts, but we need a solution to include for a task 2 different time schedules, one for the planned start and end , and a second one for the real ones. Is it possible with your solution to include 2 different date/time range- of course with different colors, etc. - on a task? Or we need to start for the planned date and actual state to use different GantTakss?
I am trying to use RadGanttView to display a series of tasks that are assigned to one person.
The problem is that the RadGanttView is just displaying a list of tasks with children. There doesn't seem to be any functionality to assign tasks to an entity , and trough that to have a sort of grouping where you can show multiple tasks on the same line.
For example Resource 1 has Task1(10.10.2010)-(10.12.2010) and Task2(24.12.2010)-(01.01.2011)
What i would like is that on the chart i show on the left side Resource1 and on the graph on the same line the 2 tasks drawn in the proper timeframe. Is this something achievable with this control ?
It seems you don't need to draw a GanttChart but to present your tasks grouped by resources. The GanttView control is not intended to be used for this. We have a separate control called RadScheduleView which supports grouping by resources. Please refer to this example for more information (it is a Silverlight example, but this can be done exactly the same way in WPF as well).
Hope this helps.

Does this Control provide Multiple GanttTasks On One Line now ? We have a project that needs to work with it.
In the current version RadGanttView control displaying multiple tasks on the same row is not an out of the box feature but it could be achieved. You can take a look at our online SDK example that shows how to achieve recurring tasks. You can download the entire repository as a zip file from this link.
You should note that there is a limitation in the current version of the control with the described approach in the sample project when a recurring task has multiple occurrences which start/end times overlap. In that scenario the task with the bigger ZIndex will overlap the other task rather then by placed under each other.
Hope this is helpful.

in March 2012 you wrote "will be implemented in Q2 2012".
Still not possible in 2014? Will this ever be supported or did you decide not to implement this fearture?
Unfortunately the logged feature request is still open and is not implemented in the RadGanttView control.
You can vote for it and keep track of its status in our feedback portal here. If we get enough demand for such functionality in the control we will consider implementing it as a built-in feature. In the meanwhile as mentioned earlier you can take a look at our RecurringTask SDK example that shows a possible approach in achieving the desired behavior.
Now that the GanttTasks natively support deadlines has this documented behaviour been deprecated?
The example basically demonstrates how to add additional custom elements in the Timeline part of the control. Indeed, there is already a native deadline property, however, this approach is still valid.
You can check the complete example in our XAML SDK Repository at the following link:
I hope this will help.
This feature multiple events or "GanttTasks" on a single line is supported in version 2016?
In its current implementation RadGanttView does not support displaying of multiple tasks on the same row out of the box. However, we suggest you to check the following example from our SDK Repository that demonstrates how to achieve a similar to the desired functionality:
Note that it has some limitations and could lead to unexpected results in certain scenarios.
Hope this helps.
Thank you, but we need to have children to each task.
Task1 : -----------------------------Task11---------------------------- ----------------------Task12--------------------------
|-> SaubTask1 : --Child1_Task11-- ----Child2_Task11--- --Child1_Task12-- --Child2_Task12--
Unfortunately, the desired functionality and appearance of RadGanttView and its Tasks is not supported in the current version of the control and there isn't any easy approach that we could suggest you in order to achieve it. We will consider this scenario as well when the feature request is going to be implemented. Meanwhile, you could vote for the item and follow it - thus when its status gets changed you will be notified.

I had a look at your SameRowRecurringTask example and I noticed that RecurringTasks can't be resized. Is this one of the limitations and unexpected results you've mentioned or can I get this functionality to work again?
in addition to my previous question I have another problem with RecurrenceTasks. When the GanttView is too big and has a horizontal scroll bar, I want to center the view on the selected task with
but the scroll bar always scolls to its initial position on the left. I only got this working with a normal "fake" GanttTask below the RecurreceTask.
Does anyone have an idea what else I could try to get the selected task to the center?
Any help would be appreciated.
Regarding your first question - indeed the inability to resize, drag and connect recurrence tasks are part of the limitations mentioned.
Regarding the second question - when scrolling to a specific GanttTask we find one container which to position with the set scrolling settings. When there are recurring tasks more than one container is available for a specific GanttTask, but only one is positioned in the center. You can find an attached project demonstrating this.
thanks for your reply and the attached project. I got the selection part working. The problem was that I tried to center the view on the selected task and not the RecurrenceTask (which contains the selected task in its Recurrence collection).
Regarding my first question. Is there a way to enable the resize function again? I've tried to resize it with an adorner but placing the GanttView in a Canvas didn't work and I couldn't find a way to set the new coordinates of the task without it.
Thanks again and best regards
I am happy to hear that you've managed to achieve the desired selection.
Regarding the resizing of a recurrence task, I am afraid that this functionality is not supported. I suggest openning a support ticket with the project you've setup so we can take a look and propose a solution if possible.
