Hello Marius,

What you could in order to show progress indicator while exporting an Excel file and Word file is to use the ExportAsync methods of UltraGridExcelExporter and UltraGridWordWriter. It will export the grid asynchronously and will provide you with progress indicator on top of it. If you want to know more about this method please visit the following link:

Please let me know if you have any additional questions.
