How to display progress on a progress bar using savefiledialog?

Question

I want to display progress of saving a file using the "SaveFileDialog" and "Progress Bar" in a windows form. The file being saved is text file (rtf, txt, ...). This is what I use to save a file:

  private void Save()
    {
        if (TabControl.TabPages.Count != 0)
        {
            SaveFileDialog.FileName = TabControl.SelectedTab.Name;
            SaveFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); //default path
            SaveFileDialog.Filter = "Rich Text Format|*.rtf";//Extensions
            SaveFileDialog.Title = "Save";

            if (SaveFileDialog.ShowDialog() == DialogResult.OK)
            {
                if (SaveFileDialog.FileName.Length > 0)
                {
                    GetCurrentDocument.SaveFile(SaveFileDialog.FileName, RichTextBoxStreamType.RichText);//Stream Type for .rtf
                }
            }
            else if (SaveFileDialog.ShowDialog() == DialogResult.Cancel)
            {
                StatusBar.Text = "Saving Cancelled."; //Makes sure it doesn't crash on cancel
            }
        }
        else
        {
            StatusBar.Text = "Can't save. No tabs are detected.";
        }
    }

The GetCurrentDocument is this:

private RichTextBox GetCurrentDocument
    {
        get
        {
            return
              (RichTextBox)TabControl.SelectedTab.Controls["Body"];
        }
    }

Thus, SaveFile() is:

RichTextBox.SaveFile Method: Saves the contents of the RichTextBox to a file. msdn page

Somehow I want to display the saving on the progress bar, or at least display a notice when the saving is finished (when the file is in the final location).

Unless your RichTextBox is gigantically long with text, saving should be a relatively short process. And event if it does take a long time, you don't have access to an enumerator that tells you the saving progress. Unknown long operations would use a marquee progress in those cases. Just put `StatusBar.Text = "Save Completed."; after your SaveFile line. — LarsTech, Jul 24 '17 at 18:42

You will need a progress bar as a Marquee style as you don't know how long it will take to save the file. Try this
