问题描述
我有一个剑道 kendoDropDownList。我正在尝试通过调用 Ajax 来填充下拉值。不幸的是,每次我单击下拉菜单时,它都会调用 Action 并返回值,但下拉列表不显示列表。我用一个简单的字典测试了几次,它对测试数据(显示在代码中)工作正常,但是当我用真实数据填充相同的数据时,它没有显示下拉值。如果我做错了什么,你能看看吗?
操作:
public ActionResult SubmitterActionTypes(int id)
{
var types = ServiceProvider.SupplementalDataService.SubmitterActionTypes()
.OrderBy(x => x.Name);
Dictionary<int,string> typesDic = new Dictionary<int,string>();
// Following Test code works fine and drop down populates with values...
/*typesDic.Add(1,"Item 1");
typesDic.Add(2,"Item 2");
typesDic.Add(3,"Item 3");
typesDic.Add(4,"Item 4");*/
// Following code does not work and dropdown does not show any result
foreach(var type in types)
{
if (type.Name!=null && type.Name != "None")
{
typesDic.Add(Convert.ToInt32(type.SubmitterActionRequiredTypeID),type.Name.ToString());
}
}
return PartialView("JsonResult",typesDic.ToList());
}
阿贾克斯:
var submitterActionRequired = $("#submitterActionRequired").kendoDropDownList({
optionLabel: "Select User Assignee...",dataTextField: "Value",dataValueField: "Key",height: 310,Width: "900px",dataSource: {
transport: {
read: function (options) {
$.ajax({
url: "/Submission/SubmitterActionTypes",dataType: "JSON",data: {
id: EntityOrganizationID
},success: function (result) {
// notify the data source that the request succeeded
options.success(result);
},error: function (result) {
// notify the data source that the request failed
options.error(result);
}
});
}
}
}
}).data("kendoDropDownList");
