In view i am using this drop dowenlist coding. i run my application default deactive value is display in dropdowen list box. i want display default Active
推荐答案
这样的:
@Html.DropDownListFor(model => model.Status, new List<SelectListItem>
{ new SelectListItem{Text="Active", Value="True"},
new SelectListItem{Text="Deactive", Value="False"}},"Select One")
如果你想激活被默认选中,然后使用选
的属性 SelectListItem
:
If you want Active to be selected by default then use Selected
property of SelectListItem
:
@Html.DropDownListFor(model => model.Status, new List<SelectListItem>
{ new SelectListItem{Text="Active", Value="True",Selected=true},
new SelectListItem{Text="Deactive", Value="False"}},"Select One")
如果使用的SelectList
,那么你必须使用的此重载并指定 SelectListItem
值
属性要设置选定的:
If using SelectList
, then you have to use this overload and specify SelectListItem
Value
property which you want to set selected:
@Html.DropDownListFor(model => model.title,
new SelectList(new List<SelectListItem>
{
new SelectListItem { Text = "Active" , Value = "True"},
new SelectListItem { Text = "InActive", Value = "False" }
},
"Value", // property to be set as Value of dropdown item
"Text", // property to be used as text of dropdown item
"True"), // value that should be set selected of dropdown
new { @class = "form-control" })
