asp.net-mvc-3 - MVC3 WebGrid - 动态创建列(foreach？)

Question

我想创建一个包含基于集合(例如 List)的列的 WebGrid。像这样的东西(这显然不起作用):

@grid.GetHtml(
  columns: grid.Columns(
    @foreach (var column in Model.ListOfColumns) {
       grid.Column(column.Name, column.Title);
    }
  )
)          

有什么好主意吗？

你可以像下面这样查看它。

Controller :

        List<WebGridColumn> columns = new List<WebGridColumn>();
        columns.Add(new WebGridColumn() { ColumnName = "Id", Header = "Id" });
        columns.Add(new WebGridColumn() { ColumnName = "Name", Header = "Name" });
        columns.Add(new WebGridColumn() { ColumnName = "Location", Header = "Location" });
        columns.Add(new WebGridColumn() { Format = (item) => { return new HtmlString(string.Format("<a href= {0}>View</a>", Url.Action("Edit", "Edit", new { Id = item.Id }))); } });
        ViewBag.Columns = columns;

查看:

   @grid.GetHtml(tableStyle: "ui-widget ui-widget-content",
                      headerStyle: "ui-widget-header",
                      columns: ViewBag.Columns
                     )
