Asp.net MVC4如何为WebGrid设置行id

从局部角度来看，我有以下几点：

    @model IList<Stratent.ScanCloud.Shared.DeliveryOrderLineDto>

    <div id="gridDiv" style="width:100%; max-height:250px; overflow:auto; border:1px solid #d1d3d4">
@{

    var grid = new  WebGrid(Model, defaultSort: "Date",
                           selectionFieldName: "SelectedRow",
                      `enter code here`     fieldNamePrefix: "gridItem", ajaxUpdateContainerId: "grid");

}

  @if (Model.Count > 0)
  {
      @grid.GetHtml(

          tableStyle: "grid",
          alternatingRowStyle: "gridrow_alternate",
          //format:@<tr id= '@item.OrderId'> </tr>,
          selectedRowStyle: "highlight",
          rowStyle: "gridrow",
          htmlAttributes: new {id = "grid"},
          columns: grid.Columns(
              grid.Column("OrderId", header: "OrderId " + Html.SortDirection(ref grid, "Client"), style: "width:9%"),
              grid.Column("Client", header: "Client " + Html.SortDirection(ref grid, "Client"), style: "width:9%"),
              grid.Column("Date", header: "Date " + Html.SortDirection(ref grid, "Date"), style: "width:9%"),
              grid.Column("Time", header: "Time " + Html.SortDirection(ref grid, "Time"), style: "width:9%"),
              grid.Column("Reference", header: "Reference " + Html.SortDirection(ref grid, "Reference"), style: "width:9%"),
              grid.Column("Order", header: "Order " + Html.SortDirection(ref grid, "Order"), style: "width:15%"),
              grid.Column("Customer", header: "Customer " + Html.SortDirection(ref grid, "Customer"), style: "width:15%"),
              grid.Column("Street", header: "Street " + Html.SortDirection(ref grid, "Street"), style: "width:9%"),
              grid.Column("Number", header: "No " + Html.SortDirection(ref grid, "Number"), style: "width:9%"),
              grid.Column("Town", header: "Town " + Html.SortDirection(ref grid, "Town"), style: "width:9%"),
              grid.Column("Crs", header: "Crs " + Html.SortDirection(ref grid, "Crs"), style: "width:15%"),
              grid.Column("Document", header: "Document " + Html.SortDirection(ref grid, "Document"), style: "width:15%")
              )


           )
  }

 @if(Model.Count == 0)
    {
        <p>There are no OrderLines available.</p>
    }

</div>

我没有收到任何身份证

在呈现的html代码中，我看到没有任何Id可从控制器发送到ActionResult

网格行不包含任何按钮，如编辑、删除。。。这不是故意的

我想为每一行定义一个id，并在选择一行时使用该id，然后从我的控制器将该id发送到ActionResult方法中

你能告诉我如何解决这个问题吗

谢谢。

您可以在设置网格时指定每列的格式：

grid.Column("InvoiceID", header: "Invoice",
                format: @<text>@Html.ActionLink((string)item.InvoiceID.ToString(),
                "Invoice", "Invoice", new { invoiceID = item.InvoiceID }, null)</text>),

grid.Column（“发票ID”，标题：“发票”，
格式：@@Html.ActionLink（（字符串）项.InvoiceID.ToString（），
“发票”，“发票”，新的{invoiceID=item.invoiceID}，null）），

---

这将生成带有ID的适当链接，并将其传递回控制器。

我知道这是一个老问题，但我也一直在努力解决这个问题

我通过修改webgrid生成的HTML来处理它，然后将其返回视图进行渲染

使用包管理器添加“HtmlAgilityPack”-用于 操纵HTML节点。您可以手动执行，但这会使 容易多了

webgrid的子类

重写GetHTML方法

将其放到视图中，并传入lambda以从模型项返回identifer值

using HtmlAgilityPack;

public class SmartGrid<T> : WebGrid
{

     ...omitted for brevity...

    public IHtmlString GetHtml(string tableStyle = null, ...omitted for brevity..., Func<T, object> getRowId = null)
    {
        IHtmlString html =  base.GetHtml(tableStyle: tableStyle, ...omitted for brevity...);

        HtmlDocument doc = new HtmlDocument();
        doc.LoadHtml(html.ToString());

        for (int i = 0; i < this.Rows.Count; i++)
        { 
            HtmlNode node = _doc.DocumentNode.SelectSingleNode(String.Format("//table/tbody/tr[{0}]", i + 1));
            node.SetAttributeValue("id", getRowId(this.Rows[i].Value));
        }

        return new HtmlString(doc.DocumentNode.OuterHtml);
    }

使用HtmlAgilityPack；
公共类SmartGrid:WebGrid
{
…为简洁起见省略。。。
公共IHtmlString GetHtml（字符串tableStyle=null，…为简洁起见省略…，Func getRowId=null）
{
IHtmlString html=base.GetHtml（tableStyle:tableStyle，…为简洁起见省略…）；
HtmlDocument doc=新的HtmlDocument（）；
doc.LoadHtml（html.ToString（））；
for（int i=0；i

这是一个“非规范化”版本来展示这个概念，在我的生产代码中，我将“SetRowIds”移到了一个新函数中

我现在使用这个截取的HTML生成行编辑模板，页脚等-它工作得很好

 public ActionResult SelectOrderLine(int id)
    {
        return RedirectToAction("Index", "DeliveryOrderLine", new {id = id});
    }

grid.Column("InvoiceID", header: "Invoice",
                format: @<text>@Html.ActionLink((string)item.InvoiceID.ToString(),
                "Invoice", "Invoice", new { invoiceID = item.InvoiceID }, null)</text>),

using HtmlAgilityPack;

public class SmartGrid<T> : WebGrid
{

     ...omitted for brevity...

    public IHtmlString GetHtml(string tableStyle = null, ...omitted for brevity..., Func<T, object> getRowId = null)
    {
        IHtmlString html =  base.GetHtml(tableStyle: tableStyle, ...omitted for brevity...);

        HtmlDocument doc = new HtmlDocument();
        doc.LoadHtml(html.ToString());

        for (int i = 0; i < this.Rows.Count; i++)
        { 
            HtmlNode node = _doc.DocumentNode.SelectSingleNode(String.Format("//table/tbody/tr[{0}]", i + 1));
            node.SetAttributeValue("id", getRowId(this.Rows[i].Value));
        }

        return new HtmlString(doc.DocumentNode.OuterHtml);
    }
