[英]How to Export two ig grids in a single excel file with different sheets
我正在使用 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具有不同工作表的单个 Excel 文件中。 我已经搜索了很多，但在互联网上找不到任何有用的东西。
有什么办法可以完成这项任务吗？
这是我的代码

由于不支持一次导出多个网格，您可以处理 exportEnding 事件，在那里调用函数导出第二个网格。 将工作簿对象作为参数传递给将导出第二个网格的函数很重要：
$("#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");
}
},
}
);}
在导出第二个网格时（这是 headerCellExporting 事件），我们尽可能早地将工作簿对象替换为我们传递给函数的对象。 所以这个工作簿在第一个工作表中有第一个网格，第二个网格将被写入第二个工作表中。
