DropDownList数据绑定
在控制器中Controller中,
List<bookInfo> bookList = bookManger.GetbookInfo();
//为前台页面DropDownList准备的数据
List<SelectListItem> deptSelectItems = new List<SelectListItem>();
deptSelectItems.Add(new SelectListItem() { Text = "请选择", Value = "-1", Selected = true });
foreach (bookInfo b in bookList)
{
SelectListItem item = new SelectListItem();
item.Text = b.bookname;
item.Value =Convert.ToString(b.bookId);
item.Selected = false;
deptSelectItems.Add(item);
}
ViewData["depBooks"] = deptSelectItems;
在页面代码中,
var dept = (List<SelectListItem>)ViewData["depBooks"];
@Html.DropDownList("ddlBooks", dept) ddlBooks为DropDownList定义的ID
或@Html.DropDownList("depBooks") id写成与ViewData定义的一个样
