create page layout using ektron CMS Api

Thanks for your reply @Chill60.I have read this article and implement a code PageModel pageModel = new PageModel(); PageData pageData = new PageData(); pageModel.Get(2, out pageData, false); WidgetData widget = new Ektron.Cms.PageBuilder.WidgetData(); widget.ControlURL = "ContentBlock.ascx"; widget.ID = 27; // For content block // You also need to set other properties like Settings, DropID, ColumnID pageData.Widgets.Add(widget); pageModel.CheckOut(pageData); pageModel.Publish(pageData); But I am getting error "com:user does not have permission";
