How to disable a ​Windows.​Forms button behavior

I have a few buttons and I use custom images for hover, pushed, etc.
I also have images for the disabled state. The problem is that when I change enabled to false, my EnabledChanged event fires and tries to change the image and also an internal event is fired that tries to desaturate the curent foreground and something very wrong happens and I get an out of memory exception.
How can I stop it from desaturating the image and leave me do the job ?

How do you draw the images on the buttons?

It doesn't matter anymore. It was a stupid homework which I finished from 4 to 5 am in the morning before the deadline
I had something like:


Image buttonPlayDisabled;
bool loaded=true;
...
Assembly assembly = Assembly.GetExecutingAssembly();
Stream stream = assembly.GetManifestResourceStream("MyProject.bitmaps.buttonPlayDisabled.jpg");

if (stream != null)
{
   buttonPlayDisabled = Image.FromStream(stream);
}
stream.Close();
if(buttonPlayDisabled == null)
    loaded=false;
...
private void playButton_EnabledChanged(object sender, EventArgs e)
{
    if (!loaded)
        return;

    if (playButton.Enabled)
    {
          playButton.Image = buttonPlayOriginal;
    }
    else
    {
          playButton.Image = buttonPlayDisabled;
    }
}


If I don't change the image on EnabledChanged event, by default, a desaturated version of the image already on my button is put in place. And it looks kind of ugly. Is there a way to disable this behavior ? I don't really care so much now, but just out of curiosity

I would have overridden the ondrawbackground method.
