Question

I want to do some visual changes on listbox items so i set DrawMode to “OwnerDrawFixed”
i want the text to be the middle of the item
vertivally it was easy by doing this:

private void listTypes_DrawItem(object sender, DrawItemEventArgs e)
{
   e.DrawBackground();
   e.Graphics.DrawString(listTypes.Items[e.Index].ToString(),
                e.Font, Brushes.Black, e.Bounds.Left, e.Bounds.Top + e.Bounds.Height/4
                , StringFormat.GenericDefault);  
   e.DrawFocusRectangle();  
}

but to center the text horizentally i need to know the text width
how to get it or is there a better way to do this

You can try with code

    void listTypes_DrawItem(object sender, DrawItemEventArgs e)
    {
        ListBox list = (ListBox)sender;
        if (e.Index > -1)
        {
            object item = list.Items[e.Index];
            e.DrawBackground();
            e.DrawFocusRectangle();
            Brush brush = new SolidBrush(e.ForeColor);
            SizeF size = e.Graphics.MeasureString(item.ToString(), e.Font);
            e.Graphics.DrawString(item.ToString(), e.Font, brush, e.Bounds.Left + (e.Bounds.Width / 2 - size.Width / 2), e.Bounds.Top + (e.Bounds.Height / 2 - size.Height / 2)); 
        }
    }
