Does this control support INotifyCollectionChanged?
I've tried to create a small sample but I'm having issues with the DropDown disappearing (even thou it claims that IsDropDownOpen = true). The control does recognize that there are items (i.e. If I press up/down, it will cycle through and suggest the various items), but it does not display the drop down.
I'm running version: 2013.1.220.1050
My overall goal is to make async web calls to populate the AutoComplete box, (using the search text as a parameter in my web methods). In my small sample, I am just using a dispatcher time to "simulate" the async population of my ObservableCollection
I've opened up a support ticket:
And uploaded a sample application.
*edit* fixed typos
