我使用Infragistics ig网格在.Net中显示数据，需要将这些网格导出到excel文件。
Infragistics也支持excel导出，但问题是，它一次支持单个网格。我想将这两个网格导出到一个带有不同工作表的excel文件中。我搜索了很多，但在互联网上找不到任何有用的东西。
有没有办法完成这项任务？
这是我的代码

答案 0 :(得分：5)
由于不支持一次导出多个网格，因此可以处理exportEnding事件，在哪里调用函数以导出第二个网格。将工作簿对象作为参数传递给将导出第二个网格的函数非常重要：
$("#exportButton").on("click", function () {
$.ig.GridExcelExporter.exportGrid($("#grid"), {
fileName: "igGrid"
},
{
exportEnding: function(sender, args) {
exportSecondGrid(args.workbook);
return false;
}
}
);});
function exportSecondGrid(workbook) {
$.ig.GridExcelExporter.exportGrid($("#grid1"), {
fileName: "igGrid",
worksheetName: "Sheet2"
},
{
headerCellExporting: function(sender, args) {
if (args.columnIndex === 0) {
sender._workbook = workbook;
sender._workbook.worksheets().add(sender._worksheet.name());
sender._worksheet = sender._workbook.worksheets(1);
sender._worksheet.rows(0).setCellValue(0, "some text");
}
},
}
);}
在导出第二个网格的最早时间（这是headerCellExporting事件），我们将工作簿对象替换为传递给函数的工作簿对象。所以这个工作簿在第一个工作表中有第一个网格，第二个网格将在第二个工作表中写入。
