弹出编辑模式下的多列

Question

我认为弹出式编辑模式是最好的编辑模式，但是对于较大的模型，弹出式会变得很长，看起来不太好。

我已经找到了解决方案，我很好奇您对此解决方案的想法/反馈/改进。

我创建了两个自定义属性：

public class NumberOfColumnsAttribute : Attribute, IMetadataAware
{
    private readonly int _numberOfColumns;

    public NumberOfColumnsAttribute(int numberOfColumns)
    {
        _numberOfColumns = numberOfColumns;
    }

    public void OnMetadataCreated(ModelMetadata metadata)
    {
        if (!metadata.AdditionalValues.ContainsKey("NumberOfColumns"))
        {
            metadata.AdditionalValues.Add("NumberOfColumns", _numberOfColumns);
        }
    }
}

public class ShowInColumnAttribute : Attribute, IMetadataAware
{
    private readonly int _column;

    public ShowInColumnAttribute(int column)
    {
        _column = column;
    }

    public void OnMetadataCreated(ModelMetadata metadata)
    {
        if (!metadata.AdditionalValues.ContainsKey("ShowInColumn"))
        {
            metadata.AdditionalValues.Add("ShowInColumn", _column);
        }
    }
}

然后使用编辑模型上方的 [NumberOfColumns(m)] 属性并使用属性上方的 [ShowInColumn(n)] 属性（假设 n=1当没有应用属性时）。

我在 Views/Shared/EditorModels/ 中创建了一个 Object.cshtml 文件，如下所示。

@if (ViewData.TemplateInfo.TemplateDepth > 1)
{
    @ViewData.ModelMetadata.SimpleDisplayText
} else {

    for (var i = 1; i <= (int)(!ViewData.ModelMetadata.AdditionalValues.ContainsKey("NumberOfColumns") ? 1 : ViewData.ModelMetadata.AdditionalValues["NumberOfColumns"]);i++)
    {
        <div class="editor-column">
        @foreach (var prop in ViewData.ModelMetadata.Properties.Where(pm => pm.ShowForEdit && !ViewData.TemplateInfo.Visited(pm) && ((int)(!pm.AdditionalValues.ContainsKey("ShowInColumn") ? 1 : pm.AdditionalValues["ShowInColumn"])) == i))
        {
            if (prop.HideSurroundingHtml) {
                @Html.Editor(prop.PropertyName)
            } else {
                <div class="editor-label">
                    @Html.Label(prop.PropertyName)
                    @(prop.IsRequired ? "*" : "")
                </div>
                <div class="editor-field">
                    @Html.Editor(prop.PropertyName)
                    @Html.ValidationMessage(prop.PropertyName, "*")
                </div>
            }
        }
        </div>
    }
    <div class="editor-seperator"></div>
}

还有以下几行 CSS：

.k-edit-form-container {
    width: auto;
}
.editor-column {
    width: 400px;
    float: left;
}
.editor-seperator {
    clear: both;
}

你怎么看？

我认为，这会简单得多。请在宽屏上运行此脚本。

                    var crudServiceBaseUrl = "//demos.telerik.com/kendo-ui/service",
                        dataSource = new kendo.data.DataSource({
                            transport: {
                                read:  {
                                    url: crudServiceBaseUrl + "/Products",
                                    dataType: "jsonp"
                                },
                                update: {
                                    url: crudServiceBaseUrl + "/Products/Update",
                                    dataType: "jsonp"
                                },
                                destroy: {
                                    url: crudServiceBaseUrl + "/Products/Destroy",
                                    dataType: "jsonp"
                                },
                                create: {
                                    url: crudServiceBaseUrl + "/Products/Create",
                                    dataType: "jsonp"
                                },
                                parameterMap: function(options, operation) {
                                    if (operation !== "read" && options.models) {
                                        return {models: kendo.stringify(options.models)};
                                    }
                                }
                            },
                            batch: true,
                            pageSize: 20,
                            schema: {
                                model: {

                            }
                        });

                    $("#grid").kendoGrid({

  };
