Hello.I have created a XamMultiColumnComboEditor with multiple selection based on a behavior. The behavior works perfectly fine, but I need to select elements programmatically from the ViewModel. I read an article written by Devin Rader who says 'The XamComboEditorSelectedItemsBehavior supports two-way binding, so changes to the SelectedCustomers collection exposed by the ViewModel will be reflected by the XamComboEditor.'.

In TwoWay binding scenario my application doesn’t work as I expected. I attach a simple application, to reproduce the issue easily.The problem is that when I select first element on the list and try to select the last one programmatically (click the button), both of them are selected.But when I first push the button that adds the last element in ViewModel, no elements are selected.Any help will be appreciated.
Hi,
I am too having the same issue. You got any solution for this?
Hello Tom,
Thank you for your post. I have been looking into it, but it seems like that I am missing something in your scenario, so could you please send an isolated sample project, where the issue is reproduced, so I can investigate it further for you.
Looking forward for your reply.
