我正在尝试使用Steve Sanderson关于编辑可变长度列表的博客文章。我已经通过 NuGet 包管理器安装了 dll,并确保命名空间在Views/web.config
文件中。但是,当我尝试编写using
语句时出现以下错误。
System.Web.Mvc.HtmlHelper<Monet.Models.AgentTransmission> does not contain a definition
for 'BeginCollectionItem' and no extension method 'BeginCollectionItem' accepting a first
argument of type 'System.Web.Mvc.HtmlHelper<Monet.Models.AgentTransmission>' could be
found (are you missing a using directive or an assmebly reference
视图/Web.config
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="HtmlHelpers.BeginCollectionItem" />
</namespaces>
局部视图(更新)
@model Monet.Models.AgentRelationshipCodes
@using (Html.BeginCollectionItem("AgentRelationshipCodes"))
{
<tr>
<td>@Html.EditorFor(model => model.EffectiveDate, "NullableDate", new { @class = "relCodeDate2" })</td>
<td>@Html.EditorFor(model => model.RelationshipId, "NullableDate", new { @class = "relDistCode1", maxlength = 3 })</td>
@Html.HiddenFor(model => model.ID)
@Html.HiddenFor(model => model.RelCodeOrdinal)
</tr>
}
控制器(以防万一)
