为什么EditorFor渲染HTML？

Question

我有以下ViewModel:

public class ShowMatrixQuestionViewModel : ShowQuestionViewModel
{

public Dictionary<MatrixRows, List<MatrixColumns>> columnrow;
public List<MatrixColumns> columns;
public List<MatrixRows> rows;

public ShowMatrixQuestionViewModel()
{
    columns = new List<MatrixColumns>();
    rows = new List<MatrixRows>();
    columnrow = new Dictionary<MatrixRows, List<MatrixColumns>>();
}
}

public class MatrixColumns
{
    public int Column_ID { get; set; }
    public int Column_Number { get; set; }
    public String Column_Description { get; set; }
    public Boolean IsAnswer { get; set; }
}

public class MatrixRows
{
    public int Row_Id { get; set; }
    public String Row_Number { get; set; }
    public String Row_Description { get; set; }
}

当我填满我的模型并尝试使用DisplayTemplate显示MatrixRows时,它不会显示任何内容.我的DisplayTemplate的名称是MatrixRows.cshtml,它放在Views/Shared/DisplayTemplates中

这是我用来显示MatrixRow的代码:

@model TestInheritance.Models.ShowMatrixQuestionViewModel

@using (Html.BeginForm())
{
    <div id="edit">
    <h2>Columns</h2>
    @foreach (var column in Model.columns)
    {
        <p>@column.GetType().Name</p>
        Html.RenderPartial("EditMatrixColumn", column);
    }
    <h2>Rows</h2>
    @foreach (var rows in Model.rows)
    {
      <p>@rows.GetType()</p>
      Html.DisplayFor(x => rows);
      //Html.RenderPartial("EditMatrixRow", rows);
    }
    </div>

    <input type="submit" value="Finished" />
}

当我使用RenderPartial时它工作正常......我做错了什么？

DisplayTemplate的代码:

@model TestInheritance.Models.MatrixRows
@using TestInheritance.Helpers

<div class="editrow">
@using (Html.BeginCollectionItem("rows")) 
{
    <span>
    Nummer:
    @Html.EditorFor(cn => Model.Row_Number)
    </span>
    <br />
    <span>
    Beskrivelse:
    @Html.EditorFor(bs => Model.Row_Description)
    </span>
}
</div>

Html.DisplayFor返回HTML.
你没有对HTML做任何事情.

您可能希望通过编写将其写入页面 @Html.DisplayFor(...)
