Question

我需要选择Quarter and Year然后提交这两个值应传递给我的存储过程"SummaryProc"并在执行后将传递ID的行.....请指导我，如果我写的代码很好。我错过了链接，因为我无法理解如何链接所有这些。工作应用将是"Enter Quarter & Year in _Summary.cshtml -> Pass values to Controller -> Execution in Repository code -> rows returned from stored proc to be displayed in SummaryTable.cshtml"

_Summary.cshtml

                     <div class="form-group">
                    <label class="control-label col-lg-4">Period:</label>
                    <div class="col-lg-8">
                        @Html.DropDownList("Quarter", new SelectListItem[] { (new SelectListItem() { Text = "Q1", Value = "1" }), (new SelectListItem() { Text = "Q2", Value = "2" }), (new SelectListItem() { Text = "Q3", Value = "3" }), (new SelectListItem() { Text = "Q4", Value = "4" }) }, "--Select Quarter--", new { @class = "form-control", id = "Quarter" })
                        <br />
                        @Html.DropDownList("Year", new SelectListItem[] { (new SelectListItem() { Text = "2016", Value = "2016" }), (new SelectListItem() { Text = "2017", Value = "2017" }) }, "--Select Year--", new { @class = "form-control", id = "Year" })
                    </div>
                </div>

                    <div class="row">
                        <div class="col-lg-offset-4" style="padding: 10px 0px 0px 0px;">
                            <input type="submit" id="submit" value="Submit" class="btn btn-lg btn-success" />
                        </div>
                    </div>

控制器代码：

  [ActionName("_Summary")]
            [HttpPost]

            public ActionResult _Summary(FloorPlanViewModel model, FormCollection form)
            {

                SummaryConfiguration sumConfig = new SummaryConfiguration();
            sumConfig.Quarter = Convert.ToInt32(form["Quarter"]);
            sumConfig.Year = Convert.ToInt32(form["Year"]);
            var details = floorService.SummaryProc(sumConfig.Quarter, sumConfig.Year);
            return PartialView("SummaryTable", details);

            }

执行存储过程的代码：

 public IEnumerable<SummaryConfiguration> SummaryProc(int Quarter, int Year)
          {
              var model = new List<SummaryConfiguration>();


              using (var dbCmd = defaultDB.GetStoredProcCommand("dbo.SummaryProc"))
              {
                  defaultDB.AddInParameter(dbCmd, "Quarter", System.Data.DbType.Int32, Quarter);
                  defaultDB.AddInParameter(dbCmd, "Year", System.Data.DbType.Int32, Year);
                  var varCmd = defaultDB.ExecuteReader(dbCmd);

                  while (varCmd.Read())
                  {
                      // add items in the list
                      model.Add(new SummaryConfiguration()
                      {
                          ID = Convert.ToString(varCmd["ID"]),
                        //rest of the code
                      });
                  }
              }
              return model;
          }

在不使用ajax的情况下处理此问题的典型方法是使用单个GET方法和视图回发到该方法。

首先创建一个视图模型来表示您的视图

public class SummaryConfigurationVM
{
    public int Quarter { get; set; }
    public int Year { get; set; }
    public IEnumerable<SummaryConfiguration> Configurations { get; set; }
    public IEnuemrable<SelectListItem> QuarterList { get; set; }
    public IEnuemrable<SelectListItem> YearListList { get; set; }
}

并添加可能适用于Quarter和Year的任何验证属性（例如[Range]属性）

，你的控制器方法将是

public ActionResult Summary(int? quarter, int? year)
{
    IEnumerable<SummaryConfiguration> configurations = new List<SummaryConfiguration>();
    if (quarter.HasValue && year.HasValue)
    {
        configurations = floorService.SummaryProc(quarter.Value, year.Value);
    }
    SummaryConfigurationVM model = new SummaryConfigurationVM()
    {
        Quarter = quarter,
        Year = year,
        Configurations = configurations,
        QuarterList = new List<SelectListItem>()
        {
            new SelectListItem(){ Text = "Q1", Value = "1" },
            ....
        },
        YearList = new List<SelectListItem>()
        {
            ....
        }
    };
    return View(model);
}

请注意，您还需要考虑验证quarter和year的值是否在预期范围内。

您的观点将是

@model SummaryConfigurationVM
....
@using (Html.BeginForm("Summary", "yourControllerName", FormMethod.Get))
{
    @Html.LabelFor(m => m.Quarter)
    @Html.DropDownListFor(m => m.Quarter, Model.QuarterList, "--Select Quarter--")
    @Html.ValidationMessageFor(m => m.Quarter)

    .... // ditto for Year

    <input type="submit" value="Submit" />
}

<table>
    <thead>
        <tr>
            <th>@Html.DisplayNameFor(m => m.Configurations.FirstOrDefault().LineID)</th>
            ....
        </tr>
    </thead>
    <tbody>
        @foreach( var item in Model.Configurations)
        {
            <tr>
                <td>@Html.DisplayFor(modelItem => item.LineID)</td>
                .... // other properties of SummaryConfiguration
            </tr>
        }
    </tbody>
</table>

您可能还会考虑在<table>块旁边呈现@if (Model.Configuraton.Any()) {（如果false，则会显示一条消息，指出未找到任何结果。
