Hello,

You could see a sample regarding this in our 'Windows Forms Feature Browser'.

If you have this installed(if you have marked 'Samples' when installing Net Advantage), you could run it from 'Start Menu' -> 'All Programs' -> 'Infragistics' -> 'Windows Forms' -> 'Samples' -> 'Samples (local)'.

When it loads, please navigate to the 'What's hot' tab and then 'Launch' the 'WinGrid Asynchronous Exporting' sample. Or you can type in the 'Search:' "'WinGrid Asynchronous Exporting'".
