當我提交時,我得到StateID始終是空的。@ Html.DropDownList選擇的值問題
任何線索我在這裏錯過了什麼?
謝謝!
HTML:
<div style="display: inline-block;">@Html.LabelFor(x => x.Common.StateID , new { @class = "SmallInput2" })</div>
<div style="display: inline-block;">@Html.DropDownList("StateID", Model.Common.StateList, "-- Select --", new { style = "width: 130px;" })</div>
代碼:
public ActionResult SignUp()
{
var model = new SignUpModel
{
Common = new Common(),
Individual = new Individual(),
Business = new Business()
};
var stateList = new SelectList(_context.States.OrderBy(w => w.StateName), "ID", "StateName", _context.States.OrderBy(w => w.StateName).FirstOrDefault().ID);
model.Common.StateList = stateList;
model.Common.StateID = _context.States.OrderBy(w => w.StateName).FirstOrDefault().ID;
return View(model);
}
型號:
[Display(Name = "State")]
public Guid StateID { get; set; }
[Display(Name = "States")]
public SelectList StateList { get; set; }
您是否像預期的那樣得到模型集的其他屬性? – horgh
@KonstantinVasilcov是的。所有其他禮儀都是正確的。 –
我認爲它可以與'StateId'這個名字連接起來......我猜如果你使用了'DropDownListFor',它會有所不同。所以,活頁夾無法綁定它...它應該有一些前綴...檢查生成的HTML其他屬性。如果你使用'..EditorFor'輔助方法,你會看到它...... – horgh
