    settings.Name = "gvEditing";
    // ...
        settings.EditFormLayoutProperties.Items.AddTabbedGroupItem(tabbedGroupSettings => {
            tabbedGroupSettings.ColumnSpan = 2;
            tabbedGroupSettings.Items.AddGroupItem(groupEmployeeInformation => {
                groupEmployeeInformation.ColumnCount = 2;
                groupEmployeeInformation.Caption = "Employee Information";
                // ...
                groupEmployeeInformation.Items.AddGroupItem(groupSettings => {
                    groupSettings.GroupBoxDecoration = GroupBoxDecoration.None;
                    groupSettings.Paddings.PaddingBottom = Unit.Pixel(0);
                    groupSettings.Items.Add("HireDate");
                    groupSettings.Items.Add("Title");
                    groupSettings.Items.Add("FireDate").Caption = "Dismissal Date";
                });
            // ...
            });
            tabbedGroupSettings.Items.AddGroupItem(groupDismissalInformation => {
                groupDismissalInformation.Caption = "Dismissal Information";
                groupDismissalInformation.Name = "DismissalInformation";
                groupDismissalInformation.Items.AddGroupItem(groupSettings => {
                    groupSettings.GroupBoxDecoration = GroupBoxDecoration.None;
                    groupSettings.Items.Add("FireReason").Caption = "Reason for Dismissal";
                    groupSettings.Items.Add("NewCompany").Caption="New Employer";
                    groupSettings.Items.Add("References");
                });
            });
        });

        settings.EditFormLayoutCreated = (sender, evargs) => {
            MVCxGridView gridView = sender as MVCxGridView;
            LayoutGroup layoutGroupDismissal = (LayoutGroup)evargs.FindLayoutItemOrGroup("DismissalInformation");

            if(layoutGroupDismissal == null) return;

            if(gridView.IsNewRowEditing) {
                layoutGroupDismissal.Visible = false;
                return;
            }
            var fireDate = gridView.GetRowValues(evargs.RowVisibleIndex, "FireDate");
            layoutGroupDismissal.ClientVisible = fireDate != null && (DateTime)fireDate != DateTime.MinValue;
        };
