Razor webgrid获取所选行数据

在我的Razor视图中，我有以下webgrid：

@{
    var grid = new WebGrid(Model, canPage: false, selectionFieldName: "VendorClassID", canSort:false);
}

 @grid.GetHtml(   
    headerStyle: "header",
    htmlAttributes: new{id = "tableGrid"},
    tableStyle: "webgrid", 
    selectedRowStyle: "webgrid-selected-row",              
    columns: grid.Columns(   
    grid.Column(header: "Select", format: @<text>@item.GetSelectLink("Select")</text>),
        grid.Column("ClassID", "ID"),
        grid.Column("ClassNum", "Class Num"),
        grid.Column("Description")
        )
        ) 

@if (grid.HasSelection)
    {
        var x = @grid.SelectedRow;       
    } 

@{
var grid=new WebGrid（模型，canPage:false，selectionFieldName:“VendorClassID”，canSort:false）；
}
@grid.GetHtml（
headerStyle:“header”，
htmlAttributes:new{id=“tableGrid”}，
表样式：“webgrid”，
selectedRowStyle：“webgrid选定行”，
列：网格。列（
grid.Column（标题：“选择”，格式：@@item.GetSelectLink（“选择”），
网格列（“ClassID”、“ID”），
grid.Column（“ClassNum”、“ClassNum”），
网格栏（“说明”）
)
) 
@if（网格选择）
{
var x=@grid.SelectedRow；
} 

---

我的理解是，当我单击生成的“选择”链接时，页面会发回，URL会添加一个参数“VendorClassID=selectrowindex”。但是，参数的值似乎是所选行的索引，这对我来说不是特别有用。是否要将参数值设置为所选行的值（ClassID等）？@grid.SelectedRow似乎也不知道行的数据，但我是MVC新手，所以也许有办法从那里获取行数据？

我找到了解决方案，通过使用

@if (grid.HasSelection)
{
   var x = grid.SelectedRow.Value.VendorClassID; 

   //logic
}

VendorClassID是我的VendorClass的一个属性。该页面有其型号的供应商类别列表

型号：

public class SchemeDetailsModel
{
    [Display(Name = "File Name")]
    public string FileName { get; set; }
    public Int64 FileId { get; set; }
    [DataType(DataType.Date)]       
    public DateTime Date { get; set; }
    [Display(Name = "Scheme Id")]
    public int SchemeId { get; set; }
    public string Status { get; set; }
    [Display(Name="Validation Error Report")]
    public string ValidationErrorReport { get; set; }
}

public class ValidationResultsModel
    {
        public string NINO { get; set; }
        public DateTime? DOB { get;set;}
        public string Transaction {  get;set; }
        public string Element {  get;set; }
        public string ErrorMessage { get; set; }
    }

            StringWriter sw = new StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            dataGrid.RenderControl(htw);
            Response.Output.Write(sw.ToString());

            Response.End();
            return View();
