                                newVendorView = vendorList.Views.Add(myviewname, viewFields, "", 100, true, true, SPViewCollection.SPViewType.Html, false);
                                newVendorView.ContentTypeId = new SPContentTypeId("0x012001");
                            }
                            else
                            {
                                newVendorView = vendorList.Views["Vendors View"];
                            }
                        }
                        catch (Exception)
                        {
                        }
                        newVendorView.ViewFields.Add("Discipline");
