我在 mvc3 中创建了一个 Web 应用程序并创建了两个部分视图，一个具有控件两个下拉列表。第二个有 webgrid，它显示来自数据库的数据。

    partialview1.cshtml
    @model Mapping.Models.SecurityIdentifierMapping

    @using (Html.BeginForm("Mapping", "Home"))
    {
        @Html.DropDownList("SecurityID", Model.PricingSecurityID, "-- Select SecurityID --")
        <br />    
        @Html.DropDownList("CUSIPID", Model.PricingSecurityID, "-- Select CUSIPID --")
        <br />
        <button type="submit">Map</button>
    }

    partialview2.cshtml
    @model IEnumerable<Mapping.Models.SecurityIdentifierMapping>

    @{
        ViewBag.Title = "Mapping";
        WebGrid grid = null;
        if (Model.Count() > 0 ){
        grid = new WebGrid(source: Model,
                                defaultSort: "Id",
                                canPage: true,
                                canSort: true,
                                rowsPerPage:20);
        }
    }


    <h2>Mapping</h2>


    @if (grid != null)
    {
    @grid.GetHtml(
                    tableStyle: "grid",
                    headerStyle: "head",
                    alternatingRowStyle: "alt",
                    columns: grid.Columns(
                                                grid.Column("", header: null, format: @<text>@Html.ActionLink("Edit", "Edit", new { id = (int)item.id })  @Html.ActionLink("Delete", "Delete", new { id = (int)item.id })</text>),
                                                grid.Column("PricingSecurityID"),
                                                grid.Column("CUSIP")
                                              )

                    )
    }
    <br />
    <p>
        @Html.ActionLink("Back", "Index")
    </p>

    in index.cshtml


    <div>
    @Html.Partial("_ControlsPartial",)
    </div>

    <div>
    @Html.Partial("_WebGridPartial")
    </div>

inside Indexcontroller.cs in Index()

     public ActionResult Index()
            {
//FOR POPULATE DROPDOWN
                //SecurityIdentifierMapping objModel = new SecurityIdentifierMapping();
                //objModel.PricingSecurityID = objRepository.GetPricingSecurityID();
                //objModel.CUSIP = objRepository.GetCUSIP();
                //return View(objModel);

              //FOR  DISPLAY DATA IN WEBGRID
                return View(dbContext.SecurityIdentifierMappings);
            }

这里的问题是webgrid partial view有@model IEnumerable<Mapping.Models.SecurityIdentifierMapping> 并且 controlpartilview正在有@model Mapping.Models.SecurityIdentifierMapping

那么我如何创建一个 VIEWMODEL.cs 一个新的类，它将有两个模型，我如何在 INDEX(() 中写入它，以便该方法也将填充下拉菜单并在 WEBGRID 中显示数据？

为什么不创建一个包含两个属性的自定义视图模型类：

public class SecurityIdentifierMappingViewModel
{
    public IEnumerable<SecurityIdentifierMapping> MappingList {get; set; }
    public SecurityIdentifierMapping Mapping {get; set; }
}

然后您可以将此自定义视图模型传递给索引视图和相应的属性作为每个部分的视图模型

然后，您的 Index 操作将如下所示：

public ActionResult Index()
{
    // single mapping
    var mapping = new SecurityIdentifierMapping();
    maping.PricingSecurityID = objRepository.GetPricingSecurityID();
    mapping.CUSIP = objRepository.GetCUSIP();

    var viewModel = new SecurityIdentifierMappingViewModel
    {
        Mapping = mapping,
        MappingList = dbContext.SecurityIdentifierMappings.ToList()
    };

    return View(viewModel);
}

并在Index.cshtml：

@model SecurityIdentifierMappingViewModel

<div>
    @Html.Partial("_ControlsPartial", Model.Mapping)
</div>

<div>
    @Html.Partial("_WebGridPartial", Model.MappingList)
</div>
