无法导出Kendo Grid中的隐藏列
我想隐藏Kendo Grid上的一些列，并将它们导出到Excel中作为可见列。 但是，使用Hidden（true）或Visible（false）没有任何意义，并且不会导出这些字段。 此页面上的解决方法不起作用。 任何想法？
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)
)
)
)
请参阅解决方案Plunker，Telerik网站上的建议解决方案。 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：隐藏第一列并显示在导出文件中

</html>我也试着用这个例子，它和我以前的答案一样，只是jQuery绑定事件会有所不同。
您只需通过添加网格事件Events(x => x.ExcelExport("excelExport"))和jQuery function excelExport(e) {}来对代码进行更改。 也只能使用Hidden(true)来隐藏网格列。
ViewModel是这样的：
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; }
}
控制器将是：
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);
}
}
并查看此：
<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
})

.Read(read => read.Action("Index_Read", "Test"))
.ServerOperation(false)
.PageSize(12)
)
)
<script type="text/javascript">
