How do I link my progress bar to my other function?

Question

I want my progress bar to start running when the user presses the Validate button. However I can only get the progress bar to move when I click on it instead. How do I link my progress bar to start when the I press the Validate button.

    private void ValidateButton_Click(object sender, EventArgs e)
    {           

        int counter = 0;
        string line;

        // Read the file and display it line by line.  
        System.IO.StreamReader file =
        new System.IO.StreamReader(FileNameBox.Text);
        while ((line = file.ReadLine()) != null)
        {
            System.Console.WriteLine(line);
            counter++;
        }

        file.Close();
        System.Console.WriteLine("There were {0} records.", counter);
        // Suspend the screen.  
        System.Console.ReadLine();
    }


    private void ProgressBar_Click()
    {
        // Display the ProgressBar control.
        ProgressBar.Visible = true;
        // Set Minimum to 1 to represent the first file being copied.
        ProgressBar.Minimum = 1;
        // Set Maximum to the total number of files to copy.
        ProgressBar.Maximum = FileNameBox.TextLength;
        // Set the initial value of the ProgressBar.
        ProgressBar.Value = 1;
        // Set the Step property to a value of 1 to represent each file being copied.
        ProgressBar.Step = 1;
        // Loop through all files to copy.
        for (int x = 1; x <= FileNameBox.TextLength; x++) ;

    }
}

The FileNameBox is a file path the user has chosen. This works as intended.

You said that ProgressBar_Click does what you want to? Then why not just add a call to it inside the ValidateButton_Click method? — MindSwipe, Mar 27 '19 at 12:32
What doesn't work exactly? The progress bar is *running* by **changing** its `Value` constantly. What you mean by *"progress bar to start"*? Do you want [indeterminate](https://stackoverflow.com/q/312936/1997232) one? — Sinatr, Mar 27 '19 at 12:33
The progress bar should not be clickable. Instead, you should turn it into it's own method and call it in the ValidateButton click.

I guess you are using winform, and you want show the realtime progress.

I think you can initialize the progressBar on Validate Button click, and update ProgressBar.Value by a Timer.

Btw, I don't understand 'ProgressBar.Maximum = FileNameBox.TextLength;' meaning, TextLength means text length, the file path text length, doesn't it ?
