    Hi,

    I am using entityFramework for my model and I have a children property that is using EntityCollection. Whenever I drag/drop a node into another node I will be prompted with "The index-based insert operation is not supported on this data binding interface." error. I have found out that the children property doesn.t have the .insert function which is the cause of this error. Any idea how can i solve this problem? Thanks you.

    Hello Xavier,

    Is it acceptable in your scenario to wrap your EntityCollection into a collection that supports index based insertion - for example an ObservableCollection?
