Place this 
 where you want to break the line (in designer).

1- First of all you need to set event on your tooltip: goto your tooltip events, double click on Draw

NB: even if your control is not a textbox but this will work for all controls because this option is just a behavior.

-Make your event look like this:

    private void tooltip1_Draw(object sender, DrawToolTipEventArgs e)
    {
        e.DrawBackground();
        e.DrawBorder();
        e.DrawText(TextFormatFlags.TextBoxControl);
    }

2- Goback to tooltip properties and change "OwnerDraw" to true.

3- Now you are able to call your event from anywhere and you can customize forecolor and backcolor now as you like, and this is a simple tip : in this example:i have a tooltip named:"tooltip1" and Textbox named:"textbox22"

  private void textBox22_MouseHover(object sender, EventArgs e)
    {
        tooltip1.ForeColor = Color.lime;
        tooltip1.BackColor = Color.black;
        tooltip1.Show("Path to a file\nExample:\n--check \"C:\\SomeDirectory\\Somefile.exe\"\nNB:\nWe don't check for the validity", this.textBox22);
    }

and you will see a semiFullcustomize Tooltip with multiline text by the "\n" which is equivalent to "Environment.NewLine", and the text should be lime text on black background.

To avoid escaping special characters as newline, easiest is to use String.Format() syntax to insert linebreaks in one or multiple places. In this case the last parameter {3}, Environment.NewLine, is inserted in two locations.

tipText = String.Format("{0:HH:mm}{3}{1:0.00}{3}{2}", ADateTime, ADouble, AString, Environment.NewLine);

Just for reference, in C++, one can simply add the "\n" tag directly in static text.

Put a newline (use Environment.NewLine) into the actual tooltip text.

You can enter a newline in the designer also (for static-text only, obviously) by clicking the dropdown arrow near the tooltip property-box, and hitting enter where you want the newline.
