I'm setting up a RadGanttView.  In all the demos, the ganttview is bound to a list of GanttTasks -- a class found in the telerik assemblies.

Is it possible to bind a RadGanttView to a list of other items?  (a custom class that exposes certain properties/methods)

The reason I ask is because we have 6 silverlight apps and use mvvm.  We currently have 1 assembly that stores the view models.  To expose a collection of GanttTasks, we would have to reference Telerik assemblies in the view model assembly, increasing the size of the xaps in all projects even if they don't use a GanttView.  It also kinda breaks mvvm in that the view model is required to know that the View needs the GanttTask class.  (the view model should not be dependant on Telerik)

Its not a big issue, because I can create a separate assembly for the view models needed for the gantt, or even put them in the silverlight project.  I was just wondering if it is possible to get by without using the GanttTask class.

Thanks,
Justin

Hi Justin,

Currently you can use your own objects which need to implement the IGanttTask interface which is also in the GanttView assembly. We are planning to add data mapping feature which will allow you to use arbitrary objects and just to specify property mappings for the properties we need like Title, Start, End, etc.

This feature is planned for the 2012 Q2 SP1 release so it should be developed shortly after the Q2 release at the middle of June. Hope this time frame is OK for you.

Hi Kholisa,

I'm not sure I fully understand what you need to do, but to add custom properties to the GanttTasks you just need to inherit from them.

Hope this helps.

Hi

Miroslav, you mentioned that Q2 release will contain mapping feature.
I checked release notes of Q2 and found no information about such a feature.
Could you tell whether mapping is implemented in Q2 version?
Regards

Hello Pawel,

We decided to postpone this feature as there are some more important features we have to work on for the GanttView control. Most probably the feature will not be ready even for the 2012 Q3 release.

Hello again, Miroslav

I noticed that you posted solution that shows example of inheritance from GanttTask class.
Could you post similar solution that shows how to prepare completely custom object that implements IGanttTask? 
There is no such example on this page (or maybe there is?), and I receive persistent error while trying to implement this interface (KeyNotFoundException)
Thank you in advance
Paweł
