In our view model we are clearing out an observerable collection (Schedule.Clear()) while a cell grid is in edit mode and we are getting the following exception.

Any ideas? We have a workaround for now where assign a new observable collection to the property but would rather clear.

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Parameter name: index

(More that was removed, but entry point from our code)

Where do you call the Clear() method for the bound collection? Could you just share with us what kind of data you are using as ItemsSource? It is a simple List, an ObservableCollection, or something else?

I have tested clearing the collection (ObservableCollection) on a button click and it was cleared fine.
