锁定动态表单分录的前三行不生效

FieldAppearance fieldAp = this.View.LayoutInfo.GetFieldAppearance(s);
DynamicObject row = this.View.Model.GetEntityDataObject(currEntity, iNewEntry);
//this.View.StyleManager.SetEnabled(fieldAp, row,null, false);
//this.View.GetFieldEditor(s, iNewEntry).SetEnabled("ShowMore", false);
this.View.StyleManager.SetEnabled(field, row, "", false);
// this.View.GetFieldEditor(s, iNewEntry).Enabled = false;
如题，这几个方法都不生效
