Question

目前对csv的导出工作正常并且目前全部导出。反正我是否可以根据所选行将过滤器导出为导出？请指教。 OnChange事件它将ID传递给控制器。但我只需要找出按钮导出是否单击，它还会点击OnChange事件

查看：

 @(Html.Kendo().Grid<HAp.Models.SessionModel>()

        .Name("List")
        .HtmlAttributes(new { @Style = "align:center; font-size:10.5px; length:100%" })
        .Columns(columns =>
        {

            columns.Bound(p => p.ReftID).Visible(false);
            columns.Bound(p => p.CreateDate);
            columns.Bound(p => p.CreateBy)
            columns.Bound(p => p.Description);



        })
        .ToolBar(toolbar => toolbar.Create())
        .ToolBar(toolBar =>
                    toolBar.Custom()
                        .Text("Export To CSV")
                        .HtmlAttributes(new { id = "export" })
                        .Url(Url.Action("Export", "Index", new { page = 1, pageSize = "~", filter = "~", sort = "~" }))
                )
        .Editable(editable => editable.Mode(GridEditMode.InLine))
        .Selectable(s => s.Mode(Kendo.Mvc.UI.GridSelectionMode.Single))
        .Pageable()
        .Scrollable()
        .DataSource(dataSource => dataSource
            .Ajax()//bind with Ajax instead server bind
            .PageSize(10)
            .ServerOperation(true)
                .Model(model => model.Id(p => p.ReftID))
                                .
            .Events(ev => ev.DataBound("onDataBound").Change("onChange"))

    )


    function onChange(e) {
           var grid = $('#List').data('kendoGrid');   //get a reference to the grid data 
           var record = grid.dataItem(grid.select()); //get a reference to the currently selected row
           var GuidID = record.ReftID;

           $.ajax({
                    type: 'POST',
                    url: "@(Url.Content("~/Test/Export/"))",
                    data: {
                            "ID": GuidID
                    }               
                });


        }

function onDataBound(e) {
        var grid = $('#List').data('kendoGrid');


            // ask the parameterMap to create the request object for you
            var requestObject = (new kendo.data.transports["aspnetmvc-server"]({ prefix: "" }))
            .options.parameterMap({
                page: grid.dataSource.page(),
                sort: grid.dataSource.sort(),
                filter: grid.dataSource.filter()
            });

            // Get the export link as jQuery object
            var $exportLink = $('#export');

            // Get its 'href' attribute - the URL where it would navigate to
            var href = $exportLink.attr('href');

            // Update the 'page' parameter with the grid's current page
            href = href.replace(/page=([^&]*)/, 'page=' + requestObject.page || '~');

            // Update the 'sort' parameter with the grid's current sort descriptor
            href = href.replace(/sort=([^&]*)/, 'sort=' + requestObject.sort || '~');

            // Update the 'pageSize' parameter with the grid's current pageSize
            href = href.replace(/pageSize=([^&]*)/, 'pageSize=' + grid.dataSource._pageSize);

            //update filter descriptor with the filters applied

            href = href.replace(/filter=([^&]*)/, 'filter=' + (requestObject.filter || '~'));

            // Update the 'href' attribute
            $exportLink.attr('href', href);
        }

    Controller:

    public FileResult Export([DataSourceRequest]DataSourceRequest request)
            {

                IEnumerable list = db.GetAll();
                MemoryStream output = new MemoryStream();
                StreamWriter writer = new StreamWriter(output, Encoding.UTF8);

                writer.Write("Ref ID,");
                writer.Write("Create Date,");
                writer.Write("Create By,");
                writer.Write("List Description,");
                writer.Write("List Status,");


                writer.WriteLine();
                foreach (vwListDetail lists in list)
                {
                    writer.Write(lists .RefID);
                    writer.Write(",");
                    writer.Write(lists .CreateDate.Value.ToShortDateString());
                    writer.Write(",");
                    writer.Write(lists .CreatedBy);
                    writer.Write(",");
                    writer.Write(lists .ListDescription);
                    writer.Write(",");



                    writer.WriteLine();
                }
                writer.Flush();
                output.Position = 0;

                return File(output, "text/comma-separated-values", "List.csv");
            }

你可以试试这个：

IEnumerable list = db.GetAll.ToDataSourceResult(request).Data;

此代码应进行任何分页，排序或过滤。
