    Hello Hanif,

    If should bind your treeview to ObservableCollection. when you change the underlying collection, the treeview item will be automatically updated.

    Please let us know if you need more help on that!

       You are true, if binded observable collection changes, UI is re-freshing. But, recently, found below issue:

    Initially, one of my RadTreeViewItem doesn't have any sub-items. So, that item doesn't have "+" for expanding. But, when I adds new sub-item, it is adding but "+" was not comming.

    I mean, even though I have one new item, it is not showing.

    Any help will appreciated.

    Thanks and regards,

    Hello srinivas nch,

    There indeed was a bug in the TreeView which results in what you describe. It should be resolved in the later versions of the controls.

    Can you tell us which version you are using?

    Is moving to a newer version an option for you?

    All the best,
    the Telerik team
