asp.netwebpageWebGrid分类显示问题

问题

请问一下如何写一个方法使分类在 WebGrid 中这样排序显示：父级分类后面显示子分类。（就像TreeView那样，只不过呢我是用在WebGrid）最终效果如图：

最佳回答

//下拉导航列表方法

@helper GetChildMenu(int menuId, List menuList)

{

var childMenuList = menuList.Where(p => p.PId == menuId).ToList();

foreach (var childMenu in childMenuList)

{

int depth2 = @childMenu.Depth + 1;



@for (int i = 1; i
{@:-

}@childMenu.Name@GetChildMenu(childMenu.Id, menuList)

}

}

//商品分类下拉导航列表

@helper NavGoodsCategory()

{

var db = Database.Open("rcdb");

List menuList = db.Query("Select * From GoodsCategory ORDER BY Id").ToList();

@GetChildMenu(0, menuList)

}
