modle.aspx.cs代码如下，定义UltraWebGridExcelExporter，然后调用Export函数。

 
protected Infragistics.WebUI.UltraWebGrid.ExcelExport.UltraWebGridExcelExporter UltraWebGridExcelExporter1;
private void Button2_Click(object sender, System.EventArgs e){
    UltraWebGridExcelExporter1.Export(this.UltraWebGrid1);          
}
