BackgroundImage property not changing.

Question

I'm unable to change the BackgroundImage property of any of my windows form controls. Is there something I need to do after I change the BackgroundImage?

Example:
<code>
public void changeCheckBoxBGImage(string path)
{
if (!File.Exists("Skins\\" + path))
{
MessageBox.Show("Skins\\" + path + " does not exist.");
return;
}
checkedListBox1.BackgroundImage = Image.FromFile("Skins\\" + path);
}
</code>

I tried using this.Invalidate() and checkedListBox1.Invalidate() but no go. Is there some property on my form that would prevent my controls from changing their BackgroundImage property?

Feels strange. Any help?

*Oh I'm also able to change the background color of these controls, but it seems like it's just a problem with BackgroundImage.

Actually the property does exist for both controls. Look at the documentation. It says that the property is not relevant to them. So that makes both of you correct to the extent that the property does not work and intellisense is misleading.

That's strange. Why doesn't it throw a compile error or at least a warning? Intellisense also show the property but I'm assuming that's because it exists in ASP.NET.

In windows forms listBox and checkedListBox don't have a background image property
