实体模型

public partial class Categoies
{
    public Categoies()
    {
        this.Posts = new HashSet<Posts>();
    }

    public int Id { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public Nullable<int> PositionId { get; set; }

    public virtual CategoryPositions CategoryPositions { get; set; }
    public virtual ICollection<Posts> Posts { get; set; }
}

查看模型

public class CategoriesViewModel
{
    public int Id { get; set; }

    [Required(ErrorMessage = "{0} alan? bo? b?rak?lmamal?d?r!")]
    [Display(Name = "Kategori …

在外部js文件中,我无法使用

url = "@Url.Action("Action", "Controller")" 
//url output : @Url.Action("Action", "Controller")
//I get IllegalPath Name error.

我写这样的时候:

url = "/Controller/Action"

如果项目位于子文件夹下,则脚本不起作用.我需要这样的东西作为相对的Url:

url = "~/Controller/Action"

我怎样才能做到这一点？谢谢.

好吧,我一直在谷歌搜索几个小时,尝试一切,无法得到任何工作.我正在使用Sharp Architecture学习MVC并生成了一些用于创建Client对象的基本表单.我想用美国州列表填写州下拉列表,让用户从该列表中选择.我能够填充列表并获取值(以保存客户端),但是当我去编辑客户端时,未选择客户端的当前状态.我在SelectList中设置了所选的值:

<li>
    <label for="Client_StateProvince">StateProvince:</label>
    <div>
        <%= Html.DropDownListFor(c=>c.Client.StateProvince, new SelectList(Model.StateProvinces, "id", "Name", Model.Client.StateProvince), "-- Select State --")%>
    </div>
    <%= Html.ValidationMessage("Client.StateProvince")%>
</li>

这似乎不够好.我错过了什么？

我有一个小数值,例如: 59625879,00

我想像这样显示这个值:59.625,879或者59625,879

我怎么能这样做@Html.DisplayFor(x => x.TAll, String.Format())？

谢谢.

我用以下代码创建一个视图

SELECT
    CONVERT(NVARCHAR, YEAR(okuma_tarihi)) + 'T1' AS sno,
    YEAR(okuma_tarihi) AS Yillar,
    SUM(toplam_kullanim_T1) AS TotalUsageValue, 'T1' AS UsageType
FROM
    TblSayacOkumalari
GROUP BY
    CONVERT(NVARCHAR, YEAR(okuma_tarihi)) + 'T1', YEAR(okuma_tarihi)

UNION ALL

SELECT
    CONVERT(NVARCHAR, YEAR(okuma_tarihi)) + 'T2' AS sno,
    YEAR(okuma_tarihi) AS Yillar,
    SUM(toplam_kullanim_T2) AS TotalUsageValue, 'T2' AS UsageType
FROM
    TblSayacOkumalari
GROUP BY
    CONVERT(NVARCHAR, YEAR(okuma_tarihi)) + 'T1', YEAR(okuma_tarihi)

UNION ALL

SELECT
    CONVERT(NVARCHAR, YEAR(okuma_tarihi)) + 'T3' AS sno,
    YEAR(okuma_tarihi) AS Yillar,
    SUM(toplam_kullanim_T3) AS TotalUsageValue, 'T3' AS UsageType
FROM
    TblSayacOkumalari
GROUP BY
    CONVERT(NVARCHAR, YEAR(okuma_tarihi)) + 'T1', YEAR(okuma_tarihi) …

Index.html(查看)

<div class="categories_content_container">
    @Html.Action("_AddCategory", "Categories")
</div>

_AddCategory.cshtml(PartialView)

<script>
    $(document).ready(function () {
        $('input[type=submit]').click(function (e) {
            e.preventDefault();
            $.ajax({
                type: "POST",
                url: '@Url.Action("_AddCategory", "Categories")',
                dataType: "json",
                data: $('form').serialize(),
                success: function (result) {
                    $(".categories_content_container").html(result);
                },
                error: function () {

                }
            });
        });
    });
</script>

@using (Html.BeginForm())
{
    // form elements
}

调节器

[HttpPost]
public ActionResult _AddCategory(CategoriesViewModel viewModel)
{
    if(//success)
    {
        // DbOperations...
        return RedirectToAction("Categories");
    }
    else
    {
        // model state is not valid...
        return PartialView(viewModel);
    }
}

问题:如果操作成功,我希望重定向到另一个页面(类别).但没有动作,没有错误信息.如果操作不成功,它就像我预期的那样工作.

我怎样才能做到这一点？如何使用AJAX帖子路由另一个页面？

区域文件夹看起来像:

Areas 
    Admin
        Controllers
            UserController
            BranchController
            AdminHomeController

项目目录如下所示:

Controller
    UserController
        GetAllUsers

区域路线登记

public override void RegisterArea(AreaRegistrationContext context)
{
    context.MapRoute(
        "Admin_default",
        "Admin/{controller}/{action}/{id}",
        new { action = "Index", id = UrlParameter.Optional },
        new { controller = "Branch|AdminHome|User" }
    );
}

项目路线登记

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
        namespaces: new string[] { "MyApp.Areas.Admin.Controllers" });
}

当我像这样路由:http://mydomain.com/User/GetAllUsers我得到资源未找到错误(404).将UserController添加到Area后,我收到此错误.

我该如何解决这个错误？

谢谢...

jquery 1.9.0中没有live()函数,但jquery.unobtrusive.ajax.js已经使用了这个函数.

我应该使用旧版本的jquery还是其他方式？

我的MVC控制器中有以下代码:

[HttpPost]
public  PartialViewResult GetPartialDiv(int id /* drop down value */)
{
    PartyInvites.Models.GuestResponse guestResponse = new PartyInvites.Models.GuestResponse();
    guestResponse.Name = "this was generated from this ddl id:";

    return PartialView("MyPartialView", guestResponse);
}

然后在我的视图顶部的javascript中:

$(document).ready(function () {

$(".SelectedCustomer").change( function (event) {
    $.ajax({
        url: "@Url.Action("GetPartialDiv/")" + $(this).val(),
        data: { id : $(this).val() /* add other additional parameters */ },
        cache: false,
        type: "POST",
        dataType: "html",
        success: function (data, textStatus, XMLHttpRequest) {
            SetData(data);
        }
    });

});

    function SetData(data)
    {
        $("#divPartialView").html( data ); // HTML DOM …

错误

Missing type map configuration or unsupported mapping.

Mapping types:
Cities_C391BA93C06F35100522AFBFA8F6BF3823972C9E97D5A49783829A4E90A03F00 -> IEnumerable`1
System.Data.Entity.DynamicProxies.Cities_C391BA93C06F35100522AFBFA8F6BF3823972C9E97D5A49783829A4E90A03F00 -> System.Collections.Generic.IEnumerable`1[[OsosPlus2.Core.DataAccess.Cities, OsosPlus2.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]

Destination path:
CustomerViewModel.Cities.Cities

Source value:
System.Data.Entity.DynamicProxies.Cities_C391BA93C06F35100522AFBFA8F6BF3823972C9E97D5A49783829A4E90A03F00

行动方法:

public ActionResult _EditCustomer(int CustomerId)
{
    Customers customer = entity.Customers.FirstOrDefault(x => x.sno == CustomerId);
    CustomerViewModel customerViewModel = new CustomerViewModel();
    customerViewModel = AutoMapper.Mapper.Map<Customers, CustomerViewModel>(customer);

    customerViewModel.Sectors = entity.Sectors;
    customerViewModel.Cities = entity.Cities;
    customerViewModel.PowerSuppliers = entity.PowerSuppliers;

    return PartialView(customerViewModel);
}

当我从实体获取客户时,我得到了上述错误.为什么我只能在获取后出现此错误？
