How to update progress bar in a modal window?

Question

Hi I'm a novice in C#. I wrote a program to export data from datagridview. While exporting a pop-up window with a progress bar will show the progress of file being written. On the main form I wrote: BackgroundWorker bgw = new BackgroundWorker(); bgw.DoWork += delegate { //Code for exporting data }; bgw.RunWorkerAsync(); FrmProgress progress = new FrmProgress(); progress.Show(); bgw.RunWorkerCompleted += delegate { progress.Close(); }; The pop-up window showed up while exporting but the progressbar on the modal window is not updated. I tried bgw.ReportProgress but getting an error. Probably I didn't use it correctly. How do I update the progressbar in modal window? Can anyone please help me with this? Thanks in advance!

Well you have missed two steps to render that possible first you set your backgroundworker WorkerReportsProgress property to true to enable worker report its progress obckWorker.WorkerReportsProgress = true; Then you have to add an event handler to your code as under obckWorker .ProgressChanged += new ProgressChangedEventHandler (object sender ProgressChangedEventArgs args) { yourprogressbar.Value = args.ProgressPercentage; } that's it. Please if you're satisfied by this answer then mark it as answered
