Using List of groups in JumpList?

[Seznam]

Hi,
I have a question, if it's possible to use in RadJumpList custom list of already grouped items (ObservableCollection<IGrouping<string, T>>) instead of just plain list, that is grouped using GroupDescriptors and SortDescriptors?

The problem is I have a collection with custom sorted items and custom sorted groups, that is incrementally loaded on the background and I am unable to make it work using just GroupDescriptors and SortDescriptors. I'd like to just create in my ViewModel my custom ObservableCollection<IGrouping<string, T>> with already sorted groups and items, that will be just displayed without any sorting or grouping, just like I use in Windows 8.1 GridView or ListView.
Thanks

Hello Martin,

Thank you for contacting us.

The RadJumpList control does not support such functionality out of the box. My suggestion is to edit the ItemTemplate of the jump list to display the items of the groups in a ListBox or similar control. I have attached a sample project that demonstrates how this can be achieved.

I hope this helps.

Ok, in this case I'd like a help - I got list of Episodes, each episode got Order, SeasonName and SeasonOrder.
I'd like to group these episodes by SeasonName, sort these groups by SeasonOrder and within each group sort the episodes by Order.
If I use just PropertyGroupDescriptor with SeasonName, then the groups are sorted alphabetically and that is unwanted.
If I use PropertyGroupDescriptor with SeasonName for grouping and PropertyGroupDescriptor with SeasonOrder for sorting, then episodes within group are sorted randomly.
How can I achieve the expected result?
Thanks
