Hi,
 
You can Create BackgroundWorker which can be used to work in background and you can handle events to perform your desired work.
 
Check MSDN Article : Background Worker[^]
 
Hope it will work for you.
Thanks.

Yes Amit,
 
Here i am using thread for export button.
When user hit the cancel button here i am aborting the thread. after aborting the thread i am deleting the file.while deleting the file i am getting the exception like 'The process cannot access the file 'D:\myCSVfile.csv' because it is being used by another process.'
Kindly give me an idea

are you using Background worker or simple Thread ?

using simple thread.
thrThreadExportProcess = new Thread(() => startExport(csvPath));
thrThreadExportProcess.Start();
thrThreadExportProcess.IsBackground = true;

Ok, Use thrThreadExportProjecss.Join() to waint for thread to abort. after that you need to write logic to delete the file.
