在我的 PartialView 中，我添加了一个带有列的网格，我需要以这种方式成为一个组合框。

settings.Columns.Add(column =>
    {
        column.FieldName = "TheFieldName";
        column.Caption = "ACaption";

        column.ColumnType = MVCxGridViewColumnType.ComboBox;
        var comboBoxProperties = column.PropertiesEdit as ComboBoxProperties;
        comboBoxProperties.DataSource = ViewData["MyListOfObjects"];
        comboBoxProperties.TextField = "Description";
        comboBoxProperties.ValueField = "Description";
        comboBoxProperties.ValueType = typeof(String);
    });

ViewData 填充在控制器的 Index 方法中，并且我检查了它是否填充了包含值的对象。

** 编辑 ** 控制器代码：

public async Task Index() { if (TempDataId == null) return RedirectToActionPermanent("Index", "AnotherController");

    // If you debug with Visual Studio the ViewData["MyListOfObjects"] is populated 
    ViewData["MyListOfObjects"] = await Worker.GetAllListOfObjects();

    MyViewViewModel myViewViewModel = new MyViewViewModel 
    {
        MyListOne = await Worker.GetAllListOfObjectsWithId(TempDataId),
        MyListTwo = new List<AnotherObject>()
    };

    return View(tipomaViewViewModel);
}

数据访问 Entity Framework Code First 方法，GetAllListOfObjects：

public async Task<List<SimpleObjectEntity>> GetAllListOfObjects()
{
    try
    {

        return await DataContext.SimpleObjectEntities.ToListAsync();
    }
    catch (Exception ex)
    {
        Debug.WriteLine(ex);
    }
    return null;
}

带有部分 GridView 的索引视图

@model Models.ViewViewModel.MyViewViewModel 
@using Internationalization
@{
    Html.EnableClientValidation();
    ViewBag.Title = Resources.MenuLeftBar;
}
<h4>@Resources.Menu- @Resources.MenuLeftBar</h4>
<div>@Html.Partial("AGridViewPartial", Model.MyListOne)</div>
<br/>
<div>@Html.Partial("AnotherWithComboboxColumnGridViewPartial", Model.MyListTwo)</div>

PopupEditForm 中的组合框没有显示任何内容。

知道有什么问题吗？

问候。
