我一直试图让它连续几天工作，这似乎是一件又一件事。最初，我最终将其跟踪到将JSON字符串中的ASP.NET日期传递回网格时出现问题。我现在正在使用JSON.NET，并且日期会以他们应该的方式回归我被困在我看起来似乎的位置。这是我的代码，返回json字符串，以及jqGrid代码:(对不起，它太长了，但我只是不想留下任何东西，以防万一这是让我搞砸的部分）！基本上，我一直坚持使用ajax调用的成功方法，我尝试添加JSONData ....现在我从Firebug得到一个错误，说： 无效的属性ID （{总：1，页：1，记录：5，[{ “ROWID”：1， “... RNAME”： “BCC”， “SubmitterID”： “BCC4010”，“苏
任何帮助都会受到极大的赞赏！我想要使用这个插件这么多，但我绝对不会试图让它工作！
先谢谢，Briana： - ）

缺少该列表的标识符：
return_value = {
total:1,
page:1,
records:5,
[{ .. some X12 messages ..}]
}
答案 1 :(得分：2)
我花了很多时间试图让jqGrid与使用JSON的ASP.NET一起工作。现在，我有它的工作，我想与你分享。希望能为其他人节省时间。
我找到了答案here。这并不是说没有其他方法可以完成这项工作（我确信有）。但这个肯定有效。
总结那些对我有所帮助的事情：
答案 2 :(得分：1)
看起来您没有添加rows属性标识符。尝试更改：
json.Append(JsonConvert.SerializeObject(objPageCollection))
到
json.Append("rows: " + JsonConvert.SerializeObject(objPageCollection))
如果这不起作用，我建议您简化问题 - 例如将数据减少到一行 - 看看是否可以使用更简单的数据，然后逐渐将更多的东西添加回其中
答案 3 :(得分：1)
实际上， tvanfosson 对“行”标识符的要求提出了一个很好的观点。我不熟悉 jMSAjax 所以我的评论可能无效。我很高兴知道它。
它可以像返回类型一样简单吗？也就是说，当评估响应时，最终得到封装的字符串而不是json对象。
我自己也去过类似的地方。我发现选项要么是，创建一个表示预期的jqGrid响应的业务对象，并返回对象而不是字符串（ASP.NET会将它序列化为JSON给你！）或者将jqGrid修改为 eval 响应两次（凌乱）。
