Hello Mark,

Thank you for contacting Infragistics!

If you want to do the exporting on the server you can look into the following documentation on the excel engine:

https://www.igniteui.com/help/excelengine-using-the-infragistics-excel-engine

You can also still export from the client by using an ajax call to get your data:

function exportGrid() {
            var gridAllData = [];
            var url = "@Url.Action("exportData")";

            $.ajax({
                url: url,
                method: "GET",
                dataType: "json",
                success: function (data) {
                    $.ig.GridExcelExporter.exportGrid($("#grid1"), {},
                    {
                        exportStarting: function (args) {
                            args._gridData = data.Records;
                        }
                    });
                },
                error: function (jqXhr, textStatus, errorThrown) {
                    console.log(errorThrown);
                }
            });
        }

“exportData” in the url is a method in the controller that returns all the data in the grid.
