<DxGrid @ref="Grid" Data="@Data" >
    <Columns>
        <DxGridDataColumn FieldName="CompanyName" />
        <DxGridDataColumn FieldName="Country" />
        <DxGridDataColumn FieldName="UnitPrice" DisplayFormat="c" />
        <DxGridDataColumn FieldName="Quantity" />
        <DxGridDataColumn FieldName="Total" UnboundType="GridUnboundColumnType.Integer" 
                          DisplayFormat="c" UnboundExpression="[UnitPrice]*[Quantity]" />
    </Columns>
</DxGrid>
<DxButton Text="Export Big Deals to XLSX" Click="ExportXlsx_Click" />
@code {
    object Data { get; set; }
    IGrid Grid { get; set; }
    protected override async Task OnInitializedAsync() {
        var invoices = await NwindDataService.GetInvoicesAsync();
        var customers = await NwindDataService.GetCustomersAsync();
        Data = invoices.OrderBy(i => i.OrderDate).Join(customers, i => i.CustomerId, c => c.CustomerId, (i, c) => {
            return new {
                OrderDate = i.OrderDate,
                CompanyName = c.CompanyName,
                City = i.City,
                Region = i.Region,
                Country = i.Country,
                UnitPrice = i.UnitPrice,
                Quantity = i.Quantity
            };
        });
    }
    async Task ExportXlsx_Click() {
        var options = new GridXlExportOptions();
        // Exports rows with Total value larger than 1000
        options.RowExporting = e => {
            if (!e.IsGroupRow) {
                if ((int)e.GetRowValue("Total") < 1000) {
                    e.Cancel = true;
                }
            }
        };
       await Grid.ExportToXlsxAsync("Big Deals", options);
    }
