我认为弹出编辑模式是最好的编辑模式,但是对于更大的模型,弹出窗口变得非常长,看起来不太好.

我找到了解决方案,我很好奇您对此解决方案的想法/反馈/增强功能.

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(当未应用任何属性时,假定n = 1).

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>
}

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？

解决方法

我想,这会简单得多.请在宽屏幕上运行此脚本.

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",destroy: {
                                    url: crudServiceBaseUrl + "/Products/Destroy",create: {
                                    url: crudServiceBaseUrl + "/Products/Create",parameterMap: function(options,operation) {
                                    if (operation !== "read" && options.models) {
                                        return {models: kendo.stringify(options.models)};
                                    }
                                }
                            },batch: true,pageSize: 20,schema: {
                                model: {
                                    id: "ProductID",fields: {
                                        ProductID: { editable: false,nullable: true },ProductName: { validation: { required: true } },UnitPrice: { type: "number",validation: { required: true,min: 1} },Discontinued: { type: "boolean" },UnitsInStock: { type: "number",validation: { min: 0,required: true } }
                                    }
                                }
                            }
                        });

                    $("#grid").kendoGrid({
                        dataSource: dataSource,pageable: true,height: 550,toolbar: ["create"],columns: [
                            { field:"ProductName",title: "Product Name" },{ field: "UnitPrice",title:"Unit Price",format: "{0:c}",width: "120px" },{ field: "UnitsInStock",title:"Units In Stock",{ field: "Discontinued",{ command: ["edit","destroy"],title: "&nbsp;",width: "250px" }],editable: "popup",edit: fnMultipleLayoutForm
                    });


function fnMultipleLayoutForm(){
  
    $(".k-edit-form-container").prepend('<div class="column1" style="display: inline-block; float: left;padding-right:30px"></div><div class="column2" style="display: inline-block;float: left;padding-right:30px;"></div>');
  
  
    $(".k-edit-form-container").children(".k-edit-label,.k-edit-field").slice(0,parseInt($(".k-edit-form-container").children(".k-edit-label,.k-edit-field").length / 2)).appendTo(".column1");


    $(".k-edit-form-container").children(".k-edit-label,.k-edit-field").appendTo(".column2");

    $(".k-edit-form-container").css("width","auto");

    $('.k-window').css({ top: '50%',left: '50%',margin: '-' + ($('.k-window').height() / 2) + 'px 0 0 -' + ($('.k-window').width() / 2) + 'px' });
  
  };
