Question

I wanted to do a Vertical Progress Bar so i found this:
Vertical progress bar

But now like if you have Horizitonal Progress Bar you can make it work from LeftToRight / RightToLeft so i want my Vertical one to Work from UpToDown and not from DownToUp like it works now..

Is it possible?

Here is my code

public class VerticalProgressBar : ProgressBar
{
    protected override CreateParams CreateParams
    {
        get
        {
            CreateParams cp = base.CreateParams;
            cp.Style |= 0x04;
            return cp;
        }
    }
}

I’m using C# .NET 3.5 Windows Forms

There doesn’t seem to be any CreateParams that support inverted vertical ProgressBar. These are the style parameters from the Windows API:

#define PBS_SMOOTH          0x01
#define PBS_VERTICAL        0x04
#define PBS_MARQUEE         0x08
#define PBS_SMOOTHREVERSE   0x10

#define PBST_NORMAL         1
#define PBST_ERROR          2
#define PBST_PAUSED         3

I tried changing the RightToLeft values to no avail. There also doesn’t seem to be a way to arbitrarily rotate a Windows Forms control.

A possible solution may be to use the WPF ProgressBar. You could rotate it 90 degrees and it should do what you’re looking for. Another option is to use a third party Progressbar control or create a custom rendered one. It should be fairly easy to render a simple flat progressbar.
