Hi Anthony,
I was not able to reproduce the problem. I ran a few tests and obtained the export in the displayed sort order each time.
// Test 1
this.myGrid.ExportToCsv( @"D:\Test1.xls" );
// Test 2
this.myGrid.ExportToExcel( @"D:\Test2.xls" );
// Test 3
ExcelExporter exporter = new ExcelExporter( this.myGrid );
exporter.Export( @"D:\Test3.xls" );
Please make sure you are using the latest version, and if the issue persists please send us a sample project reproducing the problem at support@xceed.com (also include a link to this forum thread for reference).
