我正在使用 webgrid 的 mvc 中创建一个项目。在 webgrid 我有两列，即Status和IsActive。

状态列只能包含两个值：选中或未选中。这两个值都来自数据库。

IsActive 列具有复选框，如果在 Status 列中选中状态，则该复选框处于选中状态，反之亦然。

我的控制器中有一个actionresult，它检查特定行的状态并将其反转（即）如果状态被选中，它将变为未选中，反之亦然。这是代码：

public ActionResult Add(string path,string status)
{
    on.Open();
    if (status == "unchecked")
    {
            SqlCommand cmd = new SqlCommand("SpAdRegister1", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@imagepath", path);
            cmd.ExecuteNonQuery();
        }
    }
    else
    {
        SqlCommand cmd = new SqlCommand("SpAddeRegister", con);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@imagepath", path);
        cmd.ExecuteNonQuery();
    }
    return RedirectToAction("Index", "Ad");
}

在上面的代码中，状态是相应状态列的值，路径是数据库中定义的图像的路径。

当我选中/取消选中复选框时，上面的代码应该执行。此外，复选框的状态应该是永久的（即）如果它被选中，它必须始终保持选中状态，直到我取消选中它。

编辑 这是我获取路径值并将其传递给视图的方式：

public ActionResult Index()
        {

            SqlCommand cmd = new SqlCommand("select * from Cpecial_Ad_management_tbl where [Partner Name]='"+partname+"' ", con);

            con.Open();
            SqlDataReader dr = cmd.ExecuteReader();
            List<AddDetailModel> model = new List<AddDetailModel>();
            while (dr.Read())
            {
                model.Add(new AddDetailModel()
                {

                AdName = dr["Ad_name"].ToString(),
                AdType=dr["Ad_type_name"].ToString(),
                PartnerName=dr["Partner Name"].ToString(),
                hrefurl=dr["Ad_url"].ToString(),
                startDate=dr["Start_date"].ToString(),
                endDate = dr["End_date"].ToString(),
                tagName = dr["Tag"].ToString(),
                AdPath= dr["Ad_image_path"].ToString(),
                Status = dr["Status"].ToString()              
                });
            }
            dr.Close();

            return View(model);
        }

这里的AdPath是我在另一个控制器中使用的路径。

编辑查看代码：

@model IEnumerable<EShopPartnerSetting.Models.AddDetailModel>

@{
    var grid1 = new WebGrid(source: Model.Where(m => m.AdType == "bottom_banner").ToArray(),
                                              defaultSort: "First Name",

                                              );
    var grid2 = new WebGrid(source: Model.Where(m => m.AdType == "side_banner_bottom").ToArray(),
   defaultSort: "First Name",

    var grid3 = new WebGrid(source: Model.Where(m => m.AdType == "side_banner_top").ToArray(),

    rowsPerPage: 2, fieldNamePrefix: "wg_",
    canPage: true, canSort: true,

型号代码：

 public class AddDetailModel
    {

    public string AdName { get; set; }
    public string AdType { get; set; }
    public string PartnerName { get; set; }
    public string hrefurl { get; set; }
    public string startDate { get; set; }
    public string endDate { get; set; }
    public string tagName { get; set; }
    public string AdPath { get; set; }
    public string BannerPath { get; set; }
    public string Status { get; set; }
    }

所以本质上问题是如何在复选框单击时重定向到 actionresult 以及如何根据数据库中的某些值使复选框的状态（选中/未选中）？

任何帮助将不胜感激。

如果您修改 Add 操作结果以返回某种类型的带有 json 结果的成功消息，则可以使用 javascript 异步执行此操作：

public ActionResult Add(string path, string status)
{
    //Execute your stored procedure.

    //If successful 
    return Json(new { success = true }, JsonRequestBehaviours.AllowGet);
}

$('input[name=CheckBoxName]').change(function(){
    var path = //as your model type is IEnummerable<AddDetail> you will have to select it using javascript
    var status = $(this).is(':checked') ? 'unchecked' : 'checked';
    sendRequest(path, status);
});

function sendRequest(path, status) {
    $.get('@Url.Action('Add')' + '?path=' + path + '&status=' + status, function(){
       alert('calling the actionresult add');
    }).done(function(){
       //show an update on the page
    });
}

另一方面，考虑将您的数据访问代码抽象到不同的层。

一种可能性是使用 javascript 并订阅change复选框的事件，然后重定向到此控制器操作。例如，如果你使用 jQuery，你可能会尝试这样的事情：

<script type="text/javascript">
    $(function() {
        $('table input[type="checkbox"]').change(function() {
            // determine the value of the status parameter based on whether
            // the checkbox that we clicked on was checked or unchecked
            var status = $(this).is(':checked') ? 'unchecked' : 'checked';

            // it's not quite clear where the path parameter should come from
            // but if it shown somewhere in the table you could use a jQuery 
            // selector to retrieve it
            var path = ...;

            // calculate the url to redirect to
            var url = '@Url.Action("Add")' + 
                      '?path=' + encodeURIComponent(path) + 
                      '&status' + encodeURIComponent(status);

            // redirect
            window.location.href = url;
        });
    });
</script>
