I am working with WPF TreeView
. I have bound the TreeView
with it's DataContext
property. But whenever I am trying to refresh the TreeView
by clearing all the nodes, it's not allowing. I have tried
treeview1.Items.Clear();
but it throws exception.
Please suggest me how can I solve this problem?
Because you bound the TreeView
to a collection, in your case you need to set the DataContext
property to null or an empty collection. Any similar manipulations should be done with your ObservableCollection
and not directly with TreeView
.
