Question

Yet again another issue with resizing, like many others I have used the CreateParams method of setting up a transparent label, everything looks and works great… except for when the form is re-sized the text vanishes!

Anyone have any ideas? The control is there but the text isn’t showing as if I minimize the form and then restore it shows!

public class TransparentLabel : Label
{
    public TransparentLabel()
    {
        this.SetStyle(ControlStyles.Opaque, true);
        this.SetStyle(ControlStyles.OptimizedDoubleBuffer, false);
    }

    protected override CreateParams CreateParams
    {
        get
        {
            CreateParams parms = base.CreateParams;
            parms.ExStyle |= 0x20;  // Turn on WS_EX_TRANSPARENT
            return parms;
        }
    }
    protected override void OnPaintBackground(PaintEventArgs e)
    {
        if (base.BackgroundImage == null)
        {
            e.Graphics.DrawRectangle(new System.Drawing.Pen(this.BackColor, 1), e.ClipRectangle);
        }
        else
        {
            base.OnPaintBackground(e);
        } 

    }
}

The quick solution to this was to use a Link Label control, set its background to transparent and set the link length to 0.
