Answer 1

protected override void OnPaint(PaintEventArgs e) 
{   
    base.OnPaint(e);
    StringFormat style = new StringFormat();
    style.Alignment = StringAlignment.Near;    switch (alignmentValue) 
    {        case ContentAlignment.MiddleLeft:
            style.Alignment = StringAlignment.Near;            break;        case ContentAlignment.MiddleRight:
            style.Alignment = StringAlignment.Far;            break;        case ContentAlignment.MiddleCenter:
            style.Alignment = StringAlignment.Center;            break;
    }    
    // Call the DrawString method of the System.Drawing class to write   
    // text. Text and ClientRectangle are properties inherited from
    // Control.
    e.Graphics.DrawString(
        Text, 
        Font, 
        new SolidBrush(ForeColor), 
        ClientRectangle, style);
