Drawing managed user text

Question

class starbutton : UserControl
{
    [Bindable(true)]
    [EditorBrowsable(EditorBrowsableState.Always)]
    [Browsable(false)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
    public override string Text { get { return base.Text; } set { base.Text = value; this.Invalidate(); } }

    protected override void OnPaint(PaintEventArgs e)
    {
        Graphics graphics = e.Graphics;
        SolidBrush brush2 = new SolidBrush(Color.Green);
        Point[] points =
        { 
            new Point(ClientSize.Width / 2, 0), 
            new Point(0, ClientSize.Height/4), 
            new Point(0, ClientSize.Height), 
            new Point(ClientSize.Width, ClientSize.Height)
        };
        graphics.FillPolygon(brush2, points);
        base.OnPaint(e);
    }
}

I created a user control to create a button using shapes. I managed to do this, but I added a property so that it can display text on the form, but not display text. Why doesn't he show the text?

Answer 1

You draw a strange polygon in the implementation OnPaintand do not render any text.

Add code that displays the text (i.e. using TextRenderer.DrawText after drawing the polygon:

TextRenderer.DrawText(e.Graphics, Text , this.Font, 
    new Point(10, 10), SystemColors.ControlText);
