Thanks for writing back and for clarifying your scenario.
If you remove the group header for the items that have their Category as null
, you will still be able to see them as belonging to a group - the previous one.
I suggest you simply give the group of items with no Category
a special name that clarifies that these items do not belong to a standard group.
If you however would like to hide their group header, you could handle the ItemStateChanged
event of RadJumpList
, listen for the Realized
state and set the Visibility
property of the container (RadDataBoundListBoxItem)
to null in case the realized container is mapped to that special empty group. The code would looke something like the following:
sender, ItemStateChangedEventArgs e)
RadDataBoundListBoxItem container =
container.Visibility = Visibility.Collapsed;
I hope this helps.
Let me know if you need further assistance here.
