Hello, I am setting up a grid with ExportExcel, filtering, grouping, paging and I would like to be able to retrieve the records that are the result after filtering and grouping but without being limited by the paging (that only one page comes out and not all pages).
Something similar to when you filter and / or group and export to excel

My code in view:
@(Html.EJS().Grid("Facturas")
        .DataSource(ds=>ds.Url(Url.Action("DS")).Adaptor("UrlAdaptor").CrossDomain(true))
        .AllowExcelExport()
        .ShowColumnMenu()
        .AllowPaging()
        .AllowFiltering()
        .AllowGrouping()
        .FilterSettings(f => f.Type(Syncfusion.EJ2.Grids.FilterType.Excel))
        .Columns(c =>
        {
            c.Field("EquipoId").AllowEditing(false).IsPrimaryKey(true).Add();
            c.Field("PrecioBase").Format("C2").Add();
            c.Field("IVA").AllowEditing(false).Format("C2").Add();
            c.Field("TotalCliente").AllowEditing(false).Format("C2").Add();
            c.Field("Total").AllowEditing(false).Format("C2").Add();
        })
        .PageSettings(p=>p.PageSize(5))
        .EditSettings(es =>
        {
            es.AllowEditing(true);
        })
        .Toolbar(new string[] { "Edit", "Update", "Cancel", "ExcelExport" }).ToolbarClick("tclic")
        .ActionComplete("Completo")
        .Render()
)

<script>
    function tclic(args) {
        console.log(args);
        if (args.item.id === 'Facturas_excelexport') {

            var excelExportProperties = {
                fileName: "RepEquipos_" + "@DateTime.Now" + ".xlsx"
            };
            var grid = document.getElementById("Facturas").ej2_instances[0];
            var data = grid.dataSource;
            console.log(data);
            grid.excelExport(excelExportProperties);
        }
        }
    function Completo(args) {
        console.log(args);
        if (args.requestType === "filtering") {
            console.log(args);
            window.ids = new Array();
            var rows = args.rows;
            for (var i = 0; i < rows.length; i++) {
                if (!("key" in rows[i].data)) {
                    window.ids.push(rows[i].data);
                }
            }
        }
        if (args.requestType==="grouping") {
            console.log(args);
            window.ids = new Array();
            var rows = args.rows;
            for (var i = 0; i < rows.length; i++) {
                if (!("key" in rows[i].data)) {
                    window.ids.push(rows[i].data);
                }
            }
        }
    }
    function d1() {
        var x = window.ids;
        console.log(x);
        }

    window.addEventListener('DOMContentLoaded', function () {
        window.ids = new Array();
        });
    function test(args) {
        console.log(args);
    }
</script>

Can I retrieve all records after filtering or grouping of all pages and not just the current one?

Hi Juan, 
 
Greetings from Syncfusion. 
 
Query: ”How to retrieve records after filtering / grouping without paging ”. 
 
You can achieve your requirement by using generateQuery and executeQuery methods of EJ2 DataManager. Please refer to the below code blocks and sample link for more information. 
 
    @Html.EJS().Grid("Grid").DataSource(ds => ds.Url("/Home/UrlDatasource").Adaptor("UrlAdaptor").InsertUrl("/Home/Insert").RemoveUrl("/Home/Remove") 
.UpdateUrl("/Home/Update")).Columns(col => 
{ 
    col.Field("OrderID").HeaderText("Order ID").Width("120").IsPrimaryKey(true).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add(); 
. . . . 
}).Height("400").AllowExcelExport().AllowPaging().AllowFiltering(true).AllowGrouping().AllowSorting().FilterSettings(filter => { filter.Type(Syncfusion.EJ2.Grids.FilterType.Menu); }).ToolbarClick("toolbarClick").Toolbar(new List<string> 
        () { "ExcelExport" }).Render() 
</div> 
 
<script> 
     function toolbarClick(args) { 
        var gridObj = document.getElementById("Grid").ej2_instances[0]; 
         if (args.item.id === 'Grid_excelexport') { 
 
             var query = gridObj.renderModule.data.generateQuery(true); 
        // execute the action queries in getDataModule. 
             gridObj.getDataModule().executeQuery(query).then((e) => { 
                 console.log(e.result); // you can retrieve the all data after filter and grouping 
 
             }) 
            gridObj.excelExport(); 
        } 
     } 
</script>

I already did the test with the code you provided me and it works correctly. I only have one question: How can I handle if an error occurs in:
gridObj.getDataModule().executeQuery(query).then((e) => {
            console.log(e.result); // you can retrieve the all data after filter and grouping 

        })
I really appreciate your help

Hi Juan, 
 
You can handle failure request by using the executeQuery catch method. Please find the below code example for more information. 
 
[index.cshtml] 
var query = gridObj.renderModule.data.generateQuery(true); 
                             // execute the action queries in getDataModule.. 
             new ej.data.DataManager({url:"gr"}).executeQuery(query).then((e) => { 
                 console.log(e.result); // you can retrive the all data after filter and grouping 
             }).catch((e) => { 
                 console.log(e.error); 
             }); 
 
Please get back to us if you need any further assistance on this. 
 
Regards, 
Pavithra S.
