问题描述
我有这样的code设置我的选择列表中的默认值:
公众的ActionResult寄存器()
{
IList的<国家> countryList = _countryRepository.GetAllCountry(); VAR registerViewModel =新RegisterViewModel
{
CountryId = 52,
CountryList =新的SelectList(countryList,CountryId,国家或地区名称,选择国家)
}; 返回查看(registerViewModel);
}
我有这对我的看法,这行之有效设置所选国家的价值52:
<%:Html.DropDownListFor(型号=> model.CountryId,Model.CountryList,选择国家)%GT;
然而,当我为这个创建一个模板编辑器,不选择国家的默认值
所以,我改变我的当前视图这样:
<%:Html.EditorFor(型号=> model.CountryId,新{国家= Model.CountryList})%GT;
然后,我创建我的编辑模板是这样的:
<%@控制语言=C#继承=System.Web.Mvc.ViewUserControl< System.Int64>? %GT;
&所述;%= Html.DropDownList(
的String.Empty / * * /
(的SelectList)ViewData的[国家],
选择国家
)
%GT;
解决方案
我已经通过更换code在我的控制器解决了这个:
CountryList =新的SelectList(countryList,CountryId,国家或地区名称,52 / *默认国家ID * /)
如果你有更好的解决方案,请让我知道。我会改变接受的答案。
I have this code to set the default value of my select list:
public ActionResult Register()
{
IList<Country> countryList = _countryRepository.GetAllCountry();
var registerViewModel = new RegisterViewModel
{
CountryId = 52,
CountryList = new SelectList(countryList, "CountryId", "CountryName", "Select Country")
};
return View(registerViewModel);
}
I have this on my view and this works well sets the selected country value to 52:
<%: Html.DropDownListFor(model => model.CountryId, Model.CountryList ,"Select Country") %>
However when I create an editor template for this, the default value for country is not selected
So, I change my current view to this:
<%: Html.EditorFor(model => model.CountryId,new { countries = Model.CountryList}) %>
Then I create my editor template like this:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Int64?>" %>
<%= Html.DropDownList(
String.Empty /* */,
(SelectList)ViewData["countries"],
"Select Country"
)
%>
解决方案
I have solved this by replacing the code in my controller to :
CountryList = new SelectList(countryList, "CountryId", "CountryName",52 /*Default Country Id*/)
If you have better solutions, please let me know. I will change accepted answer.
