“text” on the tree node when it is partially visible

Question

How's the text(like below "Temporary ASP.NET") hovers directly over the tree node called? Any difference from tooltip?

Can it be controlled on visibility? e.g. do not display even when the node is partially visible.

Yes, you can control this property, but not with a standard property.

If you override TreeView, and add a new CreateParams override, and add this code, then the tooltip won't appear:

protected override CreateParams CreateParams
{
    get
    {
        CreateParams parms = base.CreateParams;
        parms.Style |= 0x80;  // Turn on TVS_NOTOOLTIPS
        return parms;
    }
}
