使用客户端对象模型将数据绑定到 Sharepoint 的下拉列表

Question

情况：我目前正在通过 .Net 页面将项目添加到共享点列表，但我无法让它们正确显示。我从列表中获取了所有项目（打印机模型），但在下拉列表（模型）中显示它们并不顺利，列表仅显示 "Microsoft.Sharepoint.Client.ListItem".

如果没有注释掉 datavaluefield 和 datatextvalue，我会收到有关未找到字段的错误消息。尽管已重新创建该列（以确保内部名称正确）并在两个字段中尝试 "value" 和 "key"，但结果相同。

坦率地说，我没有想法，用谷歌搜索问题也没有帮助，更何况因为大多数解决方案都引用 SPlist，这不是一个选项。

using (ClientContext context = new ClientContext("[mysite]"))
        {
            context.Credentials = new SharePointOnlineCredentials(username, password);
            Web site = context.Web;
            List list = site.Lists.GetByTitle("Printers");
            CamlQuery query = CamlQuery.CreateAllItemsQuery();
            ListItemCollection collection = list.GetItems(query);
            context.Load(collection);
            context.ExecuteQuery();
            modell.DataSource = collection;
            //modell.DataValueField = "Printermodell";
            //modell.DataTextField = "Printermodell";
            modell.DataBind();
        }

感谢任何想法/建议！

示例代码供您参考。

using (ClientContext context = new ClientContext("https://domain.sharepoint.com/sites/Developer/"))
            {
                string userName = "user.onmicrosoft.com";
                string password = "pw";
                SecureString securePassword = new SecureString();
                foreach (char c in password.ToCharArray()) securePassword.AppendChar(c);
                context.Credentials = new SharePointOnlineCredentials(userName, securePassword);
                Web site = context.Web;
                List list = site.Lists.GetByTitle("MyList2");
                CamlQuery query = CamlQuery.CreateAllItemsQuery();
                Microsoft.SharePoint.Client.ListItemCollection collection = list.GetItems(query);
                context.Load(collection);
                context.ExecuteQuery();

                foreach (Microsoft.SharePoint.Client.ListItem item in collection)
                {
                    string text = string.Format("{0}",item.FieldValues["Title"]);
                    modell.Items.Add(new System.Web.UI.WebControls.ListItem(text, item.Id.ToString()));
                }
                //modell.DataSource = collection;
                //modell.DataValueField = "Printermodell";
                //modell.DataTextField = "Printermodell";
                //modell.DataBind();
            }
