public override bool CanInsertActivities (System.Workflow.ComponentModel.Design.HitTestInfo insertLocation, System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> activitiesToInsert);

override this.CanInsertActivities : System.Workflow.ComponentModel.Design.HitTestInfo * System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> -> bool

public override bool CanInsertActivities(HitTestInfo insertLocation, ReadOnlyCollection<Activity> activitiesToInsert)
{
    return false;
}

Public Overrides Function CanInsertActivities(ByVal insertLocation As HitTestInfo, ByVal activitiesToInsert As ReadOnlyCollection(Of Activity)) As Boolean
    Return False
End Function
