Asp.net 部分视图不起作用

Question

Main view:

@model BTGHRM.Models.EmployeeOverallReport
@{
    Layout = "~/Views/Shared/_EmployeeMain.cshtml";
}

@foreach (var item in Model.ListOfPersonalData)
{
    Html.Partial("Partial/_EmployeeOverallReportList", item);
    <br/>
}

MyPartial:

@model BTGHRM.Models.PersonalData
@{
WebGrid grid = new WebGrid(Model.ListOfWorkData, canSort: false, rowsPerPage: 15);
}

@Html.Label(Model.FirstName)
@Html.Label(Model.LastName)
@Html.Label(Model.Appointment)
@Html.Label(Model.Division)

@if (Model.ListOfWorkData.Any())
{
@grid.GetHtml(
        tableStyle: "table",
        headerStyle: "table_HeaderStyle",
        footerStyle: "table_PagerStyle",
        rowStyle: "table_RowStyle",
        alternatingRowStyle: "table_AlternatingRowStyle",
        selectedRowStyle: "table_SelectedRowStyle",
        columns: grid.Columns(
            grid.Column("ProjectName", @Resources.Localization.project, format: @<text>
                <span class="display-mode"><label id="ProjectNameLabel">@item.ProjectName</label></span>
            </text>, style: "p60"),
            grid.Column("Activity", @Resources.Localization.activity, format: @<text>
                <span class="display-mode"><label id="ActivityLabel">@item.Activity</label></span>
            </text>, style: "p60"),
            grid.Column("ProjectEndDate", @Resources.Localization.start_date, format: @<text>
                <span class="display-mode"><label id="ProjectStartDate">@item.ProjectStartDate</label></span>
            </text>, style: "p60"),
            grid.Column("ProjectEndDate", @Resources.Localization.end_date, format: @<text>
                <span class="display-mode"><label id="ProjectEndDate">@item.ProjectEndDate</label></span>
            </text>, style: "p60")
        )
)
}

My models:

public class EmployeeOverallReport
{
    //DataBlock:
    public bool PersonalDataPartBool { get; set; }
    public List<PersonalData> ListOfPersonalData { get; set; }
    //ColumnsNeeded:
    public bool EmployeeIdBool { get; set; }
    public bool FirstNameBool { get; set; }
    public bool LastNameBool { get; set; }
    public bool AppointmentBool { get; set; }
    public bool DivisionBool { get; set; }

    //DataBlock:
    public bool WorkDataPartBool { get; set; }
    public bool ProjectWorkerIdBool { get; set; }
    public bool ProjectIdBool { get; set; }
    public bool ProjectNameBool { get; set; }
    public bool ActivityBool { get; set; }
    public bool ProjectStartDateBool { get; set; }
    public bool ProjectEndDateBool { get; set; }

}

public class PersonalData
{
    //Not all
    public List<WorkData> ListOfWorkData { get; set; }
    public int EmployeeId { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Appointment { get; set; }
    public string Division { get; set; }
    //And more
}

public class WorkData
{
    public int WorkerId { get; set; }
    public int ProjectId { get; set; }
    public string ProjectName { get; set; }
    public string Activity { get; set; }
    [DisplayFormat(DataFormatString = "{0:dd MMM yyyy}")]
    public DateTime? ProjectStartDate { get; set; }
    [DisplayFormat(DataFormatString = "{0:dd MMM yyyy}")]
    public DateTime? ProjectEndDate { get; set; }
}

Bool properties are made for sorting purposes and they are not in use now. The problem is that this code returns literally nothing:

However it returns brakes and in tracing mode all models have correct data and i am able to get inside the grid with breakpoints.

Answer 1

The Html.Partial in your for loop is still calling the HtmlHelper for the Razor Page. In other words, you were still calling the function, but that return value wasn't being rendered into the view. Had your loop been

<text>
    Html.Partial("Partial/_EmployeeOverallReportList", item);
</text>

Then the Html.Partial would have shown as text
