型号:
列表< SelectListItem> ListItem = new List< SelectListItem>();
ListItem =来自表格数据中的itm
选择新的SelectList
{
Value = itm.Value,
Text = itm.Name
})。ToList( );
ListItem.Add(new SelectListItem { Value =" true",Text =" Yes"});
ListItem.Add(new SelectListItem {Value =" false",Text =" No"});
@html.DropDownListFor(m => m.Item,ListItem,new {});
Model :
List<SelectListItem> ListItem = new List<SelectListItem>();
ListItem = from itm in tabledata
select new SelectList
{
Value = itm.Value,
Text = itm.Name
}).ToList();
OR
ListItem.Add(new SelectListItem { Value = "true", Text = "Yes" });
ListItem.Add(new SelectListItem { Value = "false", Text = "No" });
@html.DropDownListFor(m=>m.Item, ListItem,new{});
