Question

我正在关注this示例，我很难在gridview中显示数据。加载页面后，它将转到GetData并返回值。

如果在我填充数据表后立即在窗口中看到计数?dtResult.Rows.Count，我得到1001。所以我知道我有数据。但是，当我调试应用程序时，我只得到三个按钮。我在这里错过了什么？

以下是aspx代码：

}

有关如何解决此问题的任何建议？

我的两分钱。

确保网格区域设置js文件位于正确的位置，并且很好地提供给您的浏览器。查看相关行： <script src="/js/trirand/i18n/grid.locale-en.js" type="text/javascript"></script> 使用F12打开您的开发人员控制台，刷新页面并在控制台上查找下载的文件和错误消息，以确定这是否顺利。
仔细检查您提供的数据是否与列配置匹配。特别注意骆驼套管。 .NET属性以大写字母开头，它们是驼峰式的，但JSON数据通常以小写字母开头。这还取决于你是否使用任何转换（如NewtonSoft和东西）。我不知道您voiceportal.dbo.clients_v表格中的内容，请指明您的架构。在您的ASPX代码中，Addressbookid和Clientno不是骆驼。它们不应该是AddressbookId和ClientNo吗？取决于您的架构以及通过电汇实际传达的内容。

asp.net中的JQGrid不显示数据（不可见）
