Progressbar while importing an excel sheet

Hello,

... I am often using the feature "Windows Forms Essential XlsIO" to import Excel sheets into a GridGrouping control in the following way:

Dim xlTable As DataTable = sheet.ExportDataTabl(sheet.UsedRange, ExcelExportDataTableOptions.ColumnNames)
me.GridGrouping.DataSource = xlTable

I have no problems with this and everything works fine. But sometimes the Excel-Sheets are really big (about 40.000 rows) and it is quite time-consuming.

I would like to show a progress bar or something else to show the working progress. Does anyone know how I can show a progressbar while the process is running?

Thank you very much for any help.

Karsten
