How to update the progress bar in a modal window?

[melryin]

Hi,

I'm a novice in C#. I wrote a program to export data from datagridview. While exporting, a pop-up window shows the progress of file exporting.

The code is as follow:

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 progress bar modal window showed up while exporting data, but the progress bar is not updated. I tried reportprogress but it didn't work. Probably I didn't use it in the right way.

Can anyone help me with this? I have no idea how to do it.

Thanks in advance!

Yes, you have to use reportprogress to show up the changes. Google BackgroundWorker and you can get many instructions for newbie that really will help you.

Hi,

Thanks for your reply. You are right, I need to ReportProgress. I think that's because I didn't set bgw.WorkerReportProgress = true. That's why I got an error message.

I appreciate for your help. =D
