The ExportAsync method exports the UltraWinGrid to Excel asynchronously, unlike the Export method which is synchronous. This is acheived using timers and is not a multi-threaded operation. You should not attempt to access the exporter Workbook, Worksheet, or file until the operation export is complete. You can determine when the process has ending by trapping the EndExport event. During the asynchronous export process, the UltraWinGrid will disable the user's ability to add, remove, delete, edit, filter, sort, or otherwise modify the state of the data during the export process. It is strongly advised that you make sure that the grid's DataSource is not modified during the asynchronous export process. If the data is modifed during the asynchonous export process, the modified data may or may not be exported in it's new state, or (more likely) the export process may be terminated entirely. Also note that you may not perform more than one export operation at a time on the same UltraWinGrid or using the same UltraGridExcelExporter, either synchronously or asynchronous. Attempting to do so will result in an System.InvalidOperationException.
