    I'm trying to use the JumpList in an MVVM app.  I'm having trouble figuring out how to bind the GroupDescritors to a property in my view model. I have not found a way to do that so I have a wierd mixture of properties like the itemsource that I can databind and then code behind that drives the pieces of the JumpList that I can't find anyway around.

    So my questions is,  is there a way to bind the GroupDescriptors to a property in the view model?

    Hi Scott,

    Thanks for contacting us and for your question.

    The GroupDescriptors property is a read-only property and thus cannot be set. Only the collection that it returns can be modified. However, since your scenario is  a good point for making this property bindable, we will consider and update the behavior of the control in this regard.

    We have updated your Telerik points for bringing our attention to this case.

    Do not hesitate to get back to us in case you have further questions or need assistance.

    Hi Derek,

    Thanks for getting back to us.

    We didn't manage to make the group descriptors bindable due to many ongoing tasks with higher priority. We apologize for the inconvenience caused.

    The GroupDescriptors collection is something like the Items collection in ItemsControl - this collection cannot be set, it is used to access the available items within the control or when items are manually added. So, instead of adding a setter to the GroupDescriptors property we may add a GroupDescriptorsSource which may be used to describe a sequence of descriptors to be internally processed and added to the GroupDescriptors collection.

    We will implement this scenario for each of the three Descriptors collections - Group, Filter and Sort. We will do our best to make this available for the first Service Pack released for Q3 2011 - that would be within a month.

    I hope this information is useful. Let me know if I can assist you in some other way.
