I'm losing the bottom of the character when displaying in a multi-color, selected item bold, listbox

Hi,  I'm having a problem with the following code.  It successfully lets me display individual items in a listbox in any color I choose, and it will highlight the selected item by writing it as bold.  The problem is that it is chopping off the bottom of the characters.  Characters like 'g' and y' get screwed up, presumably because they get overwritten when I call FillRectangle for the item which follows.

Does anyone have any ideas?  Obviously it involves the fact that I'm filling a rectangle with
Brushes.Green before I write the string.  But I can't think of any way around this.

Thanks,
Bob

private void ordersListBox_DrawItem(object sndr, System.Windows.Forms.DrawItemEventArgs e)
{
    //
    // Draw the background of the ListBox control for each item.
    // Create a new Brush and initialize to a Black colored brush by default.
    //
    e.DrawBackground();
// here you can set the colors to anything you want
    Brush fontBrush = Brushes.Black;
    Brush backBrush = Brushes.Green;
    Font boldFont = new Font(e.Font, FontStyle.Bold);

    Font font = e.Font;
    if ( e.Index == ordersListBox.SelectedIndex )
        font = boldFont;
            
    e.Graphics.FillRectangle(backBrush, e.Bounds);
    e.Graphics.DrawString(((ListBox)sender).Items[e.Index].ToString(), font,      
             fontBrush,e.Bounds,StringFormat.GenericDefault);
               
    //
    // If the ListBox has focus, draw a focus rectangle around the selected item.
    //
    e.DrawFocusRectangle();
}

For owner-drawn control you need to handle also MeasureItem. In this event handler supply item height which is enough to show all string.

I see how to to create a MeasureItem event, but I can't seem to get it to reach my breakpoint inside it.  Is there someting I need to do in order to make this event fire?

Thanks.

DrawMode property of listbox should be OwnerDrawVariable.
