这是我的第一个C#/ MVC项目,我遇到了绑定到模型的问题。我已经阅读了应用Phil Haack's Post,并使用了EditorFor作为我的所有部分视图。我需要一个自定义模型绑定器吗?请帮助MVC C#嵌套列表中的自动模型绑定
简而言之,我有一个包含条目列表的星期列表。这些条目包含的时间列表
操作:
[HttpPost]
public ActionResult SubmitRecords(List<WeekCollection> itemData)
{
//do stuff
return View();
}
型号:
public class WeekCollection
{
public WeekCollection()
{
this.OneWeek = new List<Entry>();
}
public List<Entry> OneWeek { get; set; }
}
[Bind(Exclude = "Task, Project")]
public class Entry
{
public int ProjectId { get; set; }
public virtual Projects Project { get; set; }
public int TaskId { get; set; }
public virtual Tasks Task { get; set; }
public bool Billable { get; set; }
public List<Hours> Gethours { get; set; }
}
public class Hours
{
public float NumberOfHours { get; set; }
}
浏览次数(指数)
//within partial view iteration with incrementing u (u++)
@using(@Html.BeginForm())
{
@Html.EditorFor(m => m[u].OneWeek, "TimesheetWeek")
<input type="Submit">
}
视图(TimesheetWeek)
@foreach (var value in Model)
{
v++;
if (Model.All(x => x.projectId == 0))
{
@Html.DropDownListFor(p => p[v].projectId, (IEnumerable<SelectListItem>)projectList, "Select Project", new { @class = "notSelect" })
@Html.DropDownListFor(t => t[v].taskId, (IEnumerable<SelectListItem>)taskList, "Select Task", new { @class = "notSelect" })
}
else
{
if (value.projectId != 0)
{
@Html.DropDownListFor(p => p[v].projectId, (IEnumerable<SelectListItem>)projectList, new Dictionary<string, Object> { { "class", "SelectDrop" }, { "data-selectHead", value.projectId } })
@Html.DropDownListFor(t => t[v].taskId, (IEnumerable<SelectListItem>)taskList, new Dictionary<string, Object> { { "class", "SelectDrop" }, { "data-selectHead", value.taskId } })
}
}
@Html.CheckBoxFor(b => b[v].billable)
@Html.EditorFor(h => h[v].gethours, "HoursDisplay")
@value.gethours.Sum(a => a.numberOfHours)
}
视图(HoursDisplay)
@for (var i = 0; i < Model.Count(); i++)
{
@Html.TextBoxFor(m => m[i].numberOfHours)
}
模型正确地显示所有的数据和表格数据输出公布如下:
[0].OneWeek.[0].projectId:1
[0].OneWeek.[0].taskId:1
[0].OneWeek.[0].billable:true
[0].OneWeek.[0].billable:false
[0].OneWeek.[0].gethours.[0].numberOfHours:0
[0].OneWeek.[0].gethours.[1].numberOfHours:5
[0].OneWeek.[0].gethours.[2].numberOfHours:7
[0].OneWeek.[0].gethours.[3].numberOfHours:6
[0].OneWeek.[0].gethours.[4].numberOfHours:4
[0].OneWeek.[0].gethours.[5].numberOfHours:8
[0].OneWeek.[0].gethours.[6].numberOfHours:0
我以为我听错了索引正确的,但现在得到一个空Oneweek在行动中。我究竟做错了什么?任何援助表示赞赏。 (一些重复和HTML已被删除)
非常感谢你。我没有意识到EditorFor实际上是多么有用,因此视图模型非常简单。非常有用的知识。 Thanks + Merry Christmas – user1925048
Entry.cshtml的代码是什么? – Apollo
