在 ASP.net MVC3 中如何在 WebGrid 中提供链接

Question

In ASP.NET MVC3 I am using a Webgrid to populate the data. I have a column in which I want the data in that column to have an action link. My Table looks like this

Roll No | StudentName  |  Class |  Course  |         |
======================================================
110     |  XY          |   5    |   Science| ViewDetails

I want to provide a link to each ViewDetails in the row so to move to the desired action.As well as I want to pass a value that is RollNo to the action. How this can be achieved. I tried something like this.

var grid = new WebGrid(source: Model, canPage: true, rowsPerPage: 10);
    grid.Pager(WebGridPagerModes.NextPrevious);
    @grid.GetHtml(tableStyle: "grid", 
        htmlAttributes: new { id = "DataTable" }, 
        headerStyle: "grid-header", 
        footerStyle: "grid-header", 
        alternatingRowStyle: "grid-alternating-row", 
        selectedRowStyle: "grid-selected-row", 
        rowStyle: "grid-row-style", 
        columns: grid.Columns(
           grid.Column(columnName: "RollNo", header: "RollNo"), 
           grid.Column(columnName: "StudentName", header: "StudentName"), 
           grid.Column(columnName: "Class", header: "Class"), 
           grid.Column(columnName: "Course", header: "Course"),
           grid.Column(header: "",
                  format:item => 
                    new HtmlString(Html.ActionLink("ViewDetails","Home")))); 

Answer 1

Do it with this crappy syntax:

grid.Column(
    header: "Link", 
    format: @<text>@Html.ActionLink("ViewDetails", "Home")</text>)

Inside the <text> block you can access the current line by using the variable item like this:

format: @<text>@Html.ActionLink(item.Text, "Home")</text>

Answer 2

You could just use HTML.Raw()

grid.Column(header: "",
                  format:item => 
                    HTML.Raw(Html.ActionLink("ViewDetails","Home"))));
