GridView: Degraded performance when generating a large number of dynamic columns
Performance is degraded when a large number of columns are added dynamically by binding the Columns collection via an attached behavior.

The reason for the slow performance is the use of an ObservableCollection to hold the dynamic columns and the large number of collection change notifications.

Using a RadObservableCollection with its AddRange method or suspending notifications resolves the performance issue.

We've gone ahead and updated the Binding Columns From ViewModel demo from the SDK Examples Browser to demonstrate how this collection can be used in this scenario.
