"无法导出剑道网格中的隐藏列"

Question

I want to hide some columns on Kendo Grid and export them to the excel as the visible columns. However, using Hidden(true)<\/strong> or Visible(false)<\/strong> does not make any sense and these fields are not exported. The workarounds on this<\/a> page is not working. Any idea?

@(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)
        )
    )
)

Answer 1

See this solution Plunker , suggested solution on Telerik website. To show column in your export functionality, bind this 'excelExport' event of that grid.

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;
    }
});

Answer 2

I try with this example also, it is same as my previous answer just jQuery binding event will be different.

You just need to do changes in code by adding grid event Events(x => x.ExcelExport("excelExport")) and jQuery function excelExport(e) {} . Also use only Hidden(true) to hide grid column.

ViewModel is something like this :

 public class ContactViewModel
    {
        public string NameSurname { get; set; }

        public string InstituteName { get; set; }

        public string CityName { get; set; }

        public string RegionName { get; set; }

        public string ContactMobile { get; set; }

        public string ContactAddress { get; set; }
    }

Controller will be:

public class TestController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult Index_Read([DataSourceRequest]DataSourceRequest request)
        {
            var listOfContactViewModel = new List<ContactViewModel>() { 
            new ContactViewModel(){ NameSurname  = "N1", InstituteName  = "I1", CityName ="C1",RegionName = "R1",ContactMobile = "M1", ContactAddress = "C1" },
            new ContactViewModel(){ NameSurname  = "N2", InstituteName  = "I2", CityName ="C2",RegionName = "R2",ContactMobile = "M2", ContactAddress = "C2" },
            new ContactViewModel(){ NameSurname  = "N3", InstituteName  = "I3", CityName ="C3",RegionName = "R3",ContactMobile = "M3", ContactAddress = "C3" },
            new ContactViewModel(){ NameSurname  = "N4", InstituteName  = "I4", CityName ="C4",RegionName = "R4",ContactMobile = "M4", ContactAddress = "C4" },
            new ContactViewModel(){ NameSurname  = "N5", InstituteName  = "I5", CityName ="C5",RegionName = "R5",ContactMobile = "M5", ContactAddress = "C5" }
            };

            return Json(listOfContactViewModel.ToDataSourceResult(request),JsonRequestBehavior.AllowGet);
        }

        [HttpPost]
        public ActionResult Excel_Export_Save(string contentType, string base64, string fileName)
        {
            var fileContents = Convert.FromBase64String(base64);
            return File(fileContents, contentType, fileName);
        }
    }

And View for this:

<h2>Index</h2>

@(Html.Kendo().Grid<KendoUIMVC5.Models.ContactViewModel>()
    .Name("Grid")
    .Events(x => x.ExcelExport("excelExport"))
    .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").Hidden(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", "Test"))
            )
        .DataSource(dataSource => dataSource
            .Ajax()
            .Read(read => read.Action("Index_Read", "Test"))
            .ServerOperation(false)
            .PageSize(12)
            )
)


<script type="text/javascript">
    var exportFlag = false;
    function excelExport(e)
    {
        if (!exportFlag) {
            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;
        }
    }
</script>
