How to update progress bar in a modal window?

mel C

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!

Accepted answer

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

You are absolutely right. I didn't pass the value ated and called the eventhandler that's why the progress bar will not upd.
