Blazor Syncfusion sfgrid 导出到 Excel

Question

我正在尝试将列表从过滤后的 Syncfusion 网格导出到 Excel。我按照示例中的代码进行操作。代码运行了，但似乎什么也没发生。我无法通过查看 Syncfusion 文档或谷歌搜索来解决这个问题。我错过了什么？

<SfGrid 
    ID="ExpenseGrid"
    @ref=DefaultGrid
    Toolbar="@(new List<string>() {"ExcelExport"})"
    AllowExcelExport="true"
    DataSource="@expenses"
    AllowSorting="true"
    AllowFiltering="true">
    <GridEvents OnToolbarClick="ToolbarClickHandler" TValue="Expense"></GridEvents>
<GridColumns>
    <GridColumn Field=@nameof(Expense.Item) HeaderText="Item" TextAlign="TextAlign.Center" Width="200"></GridColumn>
    <GridColumn Field=@nameof(Expense.IncurDate) HeaderText="Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Center" Width="130"></GridColumn>
    <GridColumn Field=@nameof(Expense.Cost) HeaderText="Cost" Format="C2" TextAlign

="TextAlign.Center" Width="150"></GridColumn>
        <GridColumn Field=@nameof(Expense.Category) HeaderText="Category" TextAlign="TextAlign.Center" Width="120"></GridColumn>
        <GridColumn Field=@nameof(Expense.SubCategory) HeaderText="SubCategory" TextAlign="TextAlign.Center" Width="120"></GridColumn>
    </GridColumns>
</SfGrid>

    @code {
        private List<Expense> expenses = new();
        private SfGrid<Expense> DefaultGrid;

public async Task ToolbarClickHandler(Syncfusion.Blazor.Navigations.ClickEventArgs args)
{
    if(args.Item.Id == "ExpenseGrid_excelexport")
    {
        await this.DefaultGrid.ExportToExcelAsync();
    }
}

}

    ExcelExportProperties excelExportProperties = new()
    {
        FileName = "YourFilename.xlsx",          
    };
    await ExpenseGrid.ExportToExcelAsync(excelExportProperties);
