我的ajax表单绑定有一个小问题。这是一些代码:
我的编辑操作:
[HttpPost]
public ActionResult EditProductionArticle(Article article)
{
if (ModelState.IsValid)
{
_ArticleRepository.Edit(article);
return RedirectToAction("SelectArticle", new { id = article.DrawingNumber });
}
return PartialView(viewModel);
}
这是我的观点:
@using (Ajax.BeginForm("EditProductionArticle", new AjaxOptions { HttpMethod = "POST", InsertionMode = InsertionMode.Replace, UpdateTargetId = "selectPartialArticle" }))
{
<form class="nonActive disabled" id="form">
@Html.ValidationSummary(true)
@Html.HiddenFor(model => model.productionArticle.DrawingNumber)
@Html.LabelFor(p => p.productionArticle.ArticleDescr, "Article Description")
@Html.TextBoxFor(p => p.productionArticle.ArticleDescr, new { @class = "form-control", @placeholder = "Article Description" })
@Html.ValidationMessageFor(p => p.productionArticle.ArticleDescr)
@Html.LabelFor(p => p.sellTray, "Trays")
@Html.TextBoxFor(p => p.productionArticle.SellTrayCode, new { @class = "form-control", @placeholder = "Trays" })
@Html.ValidationMessageFor(p => p.sellTray)
@Html.LabelFor(p => p.productionArticle.BotCode, "Botanical Code")
@Html.DropDownList("BotCode", null, new { @class = "form-control", @placeholder = "Botanical Code" })
@Html.ValidationMessageFor(model => model.productionArticle.BotCode, "", new { @class = "text-danger" })
@Html.LabelFor(p => p.productionArticle.CostGrpHL, "Cost Group HL")
@Html.DropDownList("CostGrpHL", null, new { @class = "form-control", @placeholder = "Cost Group HL" })
@Html.ValidationMessageFor(model => model.productionArticle.CostGrpHL, "", new { @class = "text-danger" })
<input type="submit" value="EditProductionArticle" />
</form>
}
我的问题如下:如果我将编辑操作修改为如下所示:
public ActionResult EditProductionArticle([Bind(Prefix = "productionArticle")] Article article)
{
//bla bla
}
除了下拉列表外,它还会绑定所有内容。如果我不这样做,它将绑定下拉列表,但没有别的。谁能想到办法做到这一点?
THX。
答案 0 :(得分:2)
您使用@Html.DropDownList("BotCode", null, ...)
表示您创建的下拉列表绑定到名为BotCode
的属性,该属性在您的模型中不存在。您尚未向模型显示模型,但根据关联的LabelFor()
和ValidationMessageFor()
,它包含名为productionArticle
的属性,该属性是一个复杂对象,其属性名为BotCode
假设您在GET方法中将SelectLists分配给ViewBag
属性,请为它们提供与您绑定的属性不同的名称,例如
ViewBag.BotCodeList = new SelectList(...) // or new List<SelectListItem>...
然后在视图中使用强类型帮助器绑定到模型属性
@Html.DropDownListFor(p => p.productionArticle.BotCode, (SelectList)ViewBag.BotCodeList, ...)
或...(IEnumerable<SelectListItem>)ViewBag.BotCodeList
