无法导出Kendo Grid中的隐藏列

Question

我想在Kendo Grid上隐藏一些列,并将它们作为可见列导出到excel.但是,使用隐藏(true)或Visible(false)没有任何意义,并且不会导出这些字段.此页面上的变通方法无效.任何的想法？

视图:

@(Html.Kendo().Grid<ContactViewModel>()
    .Name("Grid")
    .Columns(columns =>
        {
            columns.Bound(m => m.NameSurname).Title("Name Surname").Width("%100");
            columns.Bound(m => m.InstituteName).Title("Institute Name").Width("250px");
            columns.Bound(m => m.CityName).Title("City").Width("145px");
            columns.Bound(m => m.RegionName).Title("Region").Width("145px");
            columns.Bound(m => m.ContactMobile).Title("Mobile").Width("125px");
            columns.Bound(m => m.ContactAddress).Title("Address").Hidden(true); //I want to export these fields
            columns.Bound(m => m.ContactAddress).Title("Address").Visible(false); //I want to export these fields    
        })
    .ToolBar(toolbar =>
        {
            toolbar.Template(@<text>
                <div class="toolbar">                        
                    <button class="btn btn-primary btn-xs pull-right k-button k-button-icontext k-grid-excel">
                        <span class="k-icon k-excel"></span>
                        Liste (xls)
                    </button>
                </div>
            </text>);
        })

    .Excel(excel => excel
        .FileName("List.xlsx")
        .Filterable(true)
        .AllPages(true)
        .ProxyURL(Url.Action("Excel_Export_Save", "Controller"))
    )
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("Index_Read", "Controller"))
        .ServerOperation(false) 
        .PageSize(12)
        )
    )
)

请参阅此解决方案Plunker，这是Telerik网站上建议的解决方案。要在导出功能中显示列，请绑定该网格的“excelExport”事件。

var exportFlag = false;
$("#grid").data("kendoGrid").bind("excelExport", function (e) {
    if (!exportFlag) {
    //  e.sender.showColumn(0); for demo
    // for your case show column that you want to see in export file
        e.sender.showColumn(5);
        e.sender.showColumn(6);
        e.preventDefault();
        exportFlag = true;
        setTimeout(function () {
            e.sender.saveAsExcel();
        });
    } else {
        e.sender.hideColumn(5);
        e.sender.hideColumn(6);
        exportFlag = false;
    }
});

演示：隐藏第一列并在导出文件中显示

var exportFlag = false;
$("#grid").data("kendoGrid").bind("excelExport", function (e) {
    if (!exportFlag) {
    //  e.sender.showColumn(0); for demo
    // for your case show column that you want to see in export file
        e.sender.showColumn(5);
        e.sender.showColumn(6);
        e.preventDefault();
        exportFlag = true;
        setTimeout(function () {
            e.sender.saveAsExcel();
        });
    } else {
        e.sender.hideColumn(5);
        e.sender.hideColumn(6);
        exportFlag = false;
    }
});
