Question

有人可以在View for Dropdownlist中告诉我我做错了什么吗？我认为它是期待SelectList的下拉列表？先感谢您。

我的模特：

public class AppointmentModel
    {
        public int CustomerID { get; set; }
        public string LastName { get; set; }
        public string FirstName { get; set; }        
        public List<DateTime> ApptDates { get; set; }
    }

查看：

@{
    var grid = new WebGrid(Model, rowsPerPage: ViewBag.RowsPerPage);    
    @grid.GetHtml(columns: grid.Columns(
        grid.Column(columnName: "LastName", header: "Last Name", canSort: true, format: @<text>@item.LastName</text>),
        grid.Column(columnName: "LastName", header: "First Name", canSort: true, format: @<text>@item.Firstname</text>),
        grid.Column(columnName: "ApptDates", header: "Appointment Dates", format: @Html.DropDownList(@item.ApptDates))
        ));                                             
}

以下更改解决了此问题：

public class AppointmentModel
    {
        public int CustomerID { get; set; }
        public string LastName { get; set; }
        public string FirstName { get; set; }        
        public DateTime ApptDt { get; set; }
        public IEnumerable<SelectListItem> ApptDatesSelectList { get; set; }
    }

查看

@{
    var grid = new WebGrid(Model, rowsPerPage: ViewBag.RowsPerPage);    
    @grid.GetHtml(columns: grid.Columns(
        grid.Column(columnName: "LastName", header: "Last Name", canSort: true, format: @<text>@item.LastName</text>),
        grid.Column(columnName: "LastName", header: "First Name", canSort: true, format: @<text>@item.Firstname</text>),
        grid.Column(columnName: "ApptDates", header: "Appointment Dates", format: @<text>@Html.DropDownList("ApptDt", (IEnumerable<SelectListItem>)@item.ApptDatesSelectList)</text>)
        ));                                             
}

假设我的评论的答案是每个约会都有一个日期，您首先需要在特定日期为模型添加属性：

public class AppointmentModel
    {
        public int CustomerID { get; set; }
        public string LastName { get; set; }
        public string FirstName { get; set; }
        public DateTime AppointmentDate {get; set;}        
        public List<DateTime> ApptDates { get; set; }
    }

然后，在SelectList完成后，您将需要进行潜在约会，您可以这样实施：

@{
    var grid = new WebGrid(Model, rowsPerPage: ViewBag.RowsPerPage);    
    @grid.GetHtml(columns: grid.Columns(
        grid.Column(columnName: "LastName", header: "Last Name", canSort: true, format: @<text>@item.LastName</text>),
        grid.Column(columnName: "LastName", header: "First Name", canSort: true, format: @<text>@item.Firstname</text>),
        grid.Column(columnName: "ApptDates", header: "Appointment Dates", format: @<text> @Html.DropDownList(@item.AppointmentDate, yourSelectList )</text>)
        ));                                             
}
