Thank you for writing.
In order to create the Grouping, you need to set a GroupDescriptor
. If you want to add the groups only if there are more than 20 items, you can easily achieve this by adding a descriptor, only if RadJumpList's ItemCount
property has a value of over 20. In order to sort the items, you need to add a SortDescriptor
as well. You can have a look at the Examples solution that we provide along with RadControls' installation. It is usually located at C:\Program Files (x86)\Telerik\RadControls for Windows Phone [Version]\Examples
. There you will find the PhoneBook
example, which demonstrates the use of both Group and Sort Descriptors.
I hope this information helps.
