我有一个从 jqGrid 编辑表单中的 dataurl 填充选择列表的网格。这些值在 get 上成功填充。我将我的数据作为 json 撤回，并且对于选择列表中显示的项目，有一个带有字段 Id 和 Name 的自定义类型的 LookupItem - 这部分工作正常。例如，我有一个代表预定课程的对象模型（在下面的第二个代码示例中），它有一个 LookupItem 类型的 Location 字段，而 LookupItem 有 Id 和 Name 字段。
我的问题是，尽管在我的 ActionResult 方法中，这些字段没有发回服务器 - 我得到空值。我添加了一个 custom_func 函数并验证了 value 参数包含我正在寻找的 Id，但我不确定如何将其发布到 ActionResult 方法。有任何想法吗？
HTML/jqGrid 代码：
$("#grid").jqGrid({
url: 'ABC.Admin/CourseAdmin/GetScheduledCourses/',
datatype: 'json',
jsonReader: { repeatitems: false },
mtype: 'GET',
colNames: ['Id', 'Date', 'LocationId', 'Location', 'TimeId', 'Time', 'CostId', 'Cost', 'InstructorId', 'Instructor', 'Additional Info'],

function locationCheck(value, colname) {
debugger;
if (value < 0 || value > 20)
return [false, "Please enter value between 0 and 20"];
else
return [true, ""];
}
ScheduledCourse 的对象模型：
public class ScheduledCourse
{
public ScheduledCourse() { }
//for admin scheduled course page
public ScheduledCourse(int scheduledCourseId, string scheduledCourseDate, int locationId, string locationName,
int timeId, string timeName, int costId, string costName, int instructorId, string instructorName, string additionalInfo)
{
this.ScheduledCourseId = scheduledCourseId;
this.ScheduledCourseDate = scheduledCourseDate;
this.Location = new LookupItem(locationId, locationName);
this.Time = new LookupItem(timeId, timeName);
this.Cost = new LookupItem(costId, costName);
this.Instructor = new LookupItem(instructorId, instructorName);
this.AdditionalInfo = additionalInfo;
}
public int ScheduledCourseId { get; set; }
public string ScheduledCourseDate { get; set; }
public LookupItem Location { get; set; }
public LookupItem Time { get; set; }
public LookupItem Cost { get; set; }
public LookupItem Instructor { get; set; }
public string UserName { get; set; }
public string AdditionalInfo { get; set; }
}
public class LookupItem
{
public LookupItem(int id, string name)
{
this.Id = id;
this.Name = name;
}
public int Id { get; set; }
public string Name { get; set; }
}
控制器代码：
//colNames: ['Id', 'Date', 'LocationId', 'Location', 'TimeId', 'Time', 'CostId', 'Cost', 'InstructorId', 'Instructor', 'Additional Info'],
[HttpPost]
public ActionResult UpdateScheduledCourse(string oper, int id, string scheduledCourseDate, string location, string locationId, string timeId,
string timeName, string costId, string costName, string instructorId, string instructorName, string additionalInfo)
{
Models.ScheduledCourseProvider p = new Models.ScheduledCourseProvider();
//Models.ScheduledCourse o = new Models.ScheduledCourse(
// id, scheduledCourseDate, Convert.ToInt32(locationId), locationName, Convert.ToInt32(timeId), timeName, Convert.ToInt32(costId),
// costName, Convert.ToInt32(instructorId), instructorName, additionalInfo);
//bool saved = p.UpdateScheduledCourse(o);
bool saved = false;
if (!saved)
{
Response.StatusCode = 500;
return Content("Record not saved!");
}
else
{
return Json(false);
}
}
以下是在控制器中调用 ActionResult 方法时传递给服务器的参数 (http://localhost:30320/OrchardLocal/ABC.Admin/CourseAdmin/UpdateScheduledCourse/) - 请注意正在使用的点符号，因为我是使用共享类型的 LookupItem：
ScheduledCourseDate=07%2F01%2F2011&Location.Name=10016&Time.Name=1014&Cost.Name=1001&Instructor.Name=10001&AdditionalInfo=blahblahblah&oper=edit&id=12126
