FolderBrowserDialog shows incorrect SelectedPath after new folder is being created and renamed

Question

The dialog will return incorrect SelectedPath when:

1. Once shown, click the New Folder button
2. Type in some name for the new folder
3. Click OK, **without pressing ente

Code used:

   FolderBrowserDialog dialog = new FolderBrowserDialog();
   dialog.ShowDialog();
   Console.WriteLine(dialog.SelectedPath);

Any suggestions how to overcome this and get the correct path for the renamed new folder?

UPDATE I have tested this on Windows 7, 8.1 and 10. It is reproducible on 7 and 10, while in 8.1 it seems to work correctly.

I wrote the suggested workaround from emoreau99 . Ugly but it works.

    public string GetPathFromFolderBrowserDialog()
    {
        var path = "";
        var fbd = new FolderBrowserDialog();

        if (fbd.ShowDialog() == DialogResult.OK)
        {
            path = fbd.SelectedPath;

            if (!Directory.Exists(path))
            {
                var lastCreatedDir = new DirectoryInfo(path).Parent
                    .GetDirectories()
                    .OrderByDescending(d => d.LastWriteTimeUtc)
                    .First();

                path = lastCreatedDir.FullName;
            }
        }

        return path;
    }

Can you open the dialog like this...

DialogResult result = openFileDialog1.ShowDialog();

and check the result before using the property SelectedPath

if(result == DialogResult.OK) 

Answer 3

I found the correct answer here: Problem with FolderBrowserDialog

If you explicitly set the property .ShowNewFolderButton = True, then .SelectedPath will correctly return the updated new folder name.

It's an odd one, because .ShowNewFolderButton is True by default, but this solution fixed the problem for me.
