我在使用 VS2010 的 ASP.NET MVC 应用程序中使用 JqGrid。我的 Grid 似乎无法在我的视图上正确呈现，并且不允许我访问视图上的其他控件（包括整个页面）。看画面吹：
网格中的行：
没有任何行的网格：
但是一旦我修改并将数据提交回控制器内联编辑输入页面就可以访问了。
我的脚本：
var last_selected_row;
$(function () {
var outerwidth = $('#studentList').width() - 10; ////Keep Grid 10 pixel smaller than its parent container
$('#studentGrid').jqGrid({
// Ajax related configurations
//url to send request to
url: "/Registration/LoadStudents",
datatype: "json",
mtype: "POST",
// Specify the column names
colNames: ["StudentID", "StudentName", "Status", "Grades", "StartDate", "EndDate", "EarnedDate", "DroppedDate"],
// Configure the columns
colModel: [
{ name: "StudentID", index: "StudentID", width: 0, align: "left", key: true },
{ name: "StudentName", index: "StudentName", editrules: { required: true, integer: false }, width: 100, title: "Name", align: "left", editable: true, stype: 'text', sortable: true },
{ name: "Status", index: "Status", width: 70, align: "left", editable: true, edittype: "checkbox", editoptions: { value: "true:false"} },
{ name: "Grades", index: "Grades", width: 80, align: "left", editable: true, edittype: "select", editoptions:
{
dataUrl: "/Registration/GetAllGrades",
buildSelect: function (data) {
//var d = $.parseJSON(data);
var jqGridAssemblyTypes = $.parseJSON(data);
var s = '<select>';
if (jqGridAssemblyTypes && jqGridAssemblyTypes.length) {
for (var i = 0, l = jqGridAssemblyTypes.length; i < l; i++) {
var ri = jqGridAssemblyTypes[i];
s += '<option value="' + ri.Value + '">' + ri.Text + '</option>';
}
}
return s + "</select>";
},
dataInit: function (elem) {
var v = $(elem).val();
////Set other column value here
},

我的控制器：
public ActionResult Index()
{
PopulateUserContextViewBags();
List<string> grades = new List<string>();
grades.Add("Grades 11 and 12");
grades.Add("Grades 12");
grades.Add("Grades 11");
grades.Add("Grades 10");
grades.Add("All Grades");
// TODO:
Models.RegistrationModel model = new Models.RegistrationModel()
{
AvailableGrades = new SelectList(grades, "Grades 11 and 12")
};
return View(model);
}
public ActionResult LoadStudents()
{
var objmodel = Models.RegistrationRepository.GetStudents();
return Json(objmodel, JsonRequestBehavior.AllowGet);
//return Json(null, JsonRequestBehavior.AllowGet);
}
public JsonResult EditStudents(Models.RegistrationModel registrationModel)
{
// registrationModel.StudentID = id;
return Json(null, JsonRequestBehavior.AllowGet);
}
我正在使用 JqGrid 4.5.1。我已经在 IE9 和 Firefox 22.0 中测试了这段代码。有什么帮助吗？？
