{

bool isUpdate = false;

if (visioObjToUpdate.ModifiedDate == DateTime.MinValue)

visioObjToUpdate.ModifiedDate = DateTime.Now;

VisioShapeData entity = DBContext.VisioShapeDatas.Where(a => a.ID == visioObjToUpdate.ID).FirstOrDefault();

entity.Level4Id = visioObjToUpdate.Level4Id;

if (DBContext.SaveChanges() > 0)
