Rich Textbox Problem   

I'd like to create a rich textbox which inherits from TextBox:

    public class MyTextBox : TextBox
    {
        protected override void Render(HtmlTextWriter writer)
        {
            base.Render(writer);
            LinkButton button = new LinkButton();
            button.Text = "Button";
            button.RenderControl(writer);
        }
    }

But in the output produced the linkbutton is no longer a LinkButton
but just plain text. If i inherit from CompositeControl everything
woks find but then my testbox is no longer a TextBox.

Is there a way to make my linkbutton work and my textbox remains a
TextBox?

Should work.
But be sure to give the control a ID.

What is the produced Output looks like?

Hi Peter,

the output produced is a TextBox and the text of the button. The
functionality of the LinkButton is lost. It's just text and not a
link.

Hi Wolfgang

Do it like so:
    public class MyTextBox : TextBox
    {
protected override void OnInit(.....) {
LinkButton b = new LinkButton();
b.ID = "someID";
b.Text = "someText";
this.Controls.Add(b);
}
        protected override void Render(HtmlTextWriter writer)
        {
            base.Render(writer);
            button.RenderControl(writer);
        }
    }

Many thaks, Peter. The control is working, now. The source code now
is:

    public class MyTextBox : TextBox
    {
        protected override void OnInit(EventArgs e)
        {
            LinkButton button = new LinkButton();
            button.Text = "Button";
            this.Controls.Add(button);
        }
        protected override void Render(HtmlTextWriter writer)
        {
            base.Render(writer);
            base.RenderChildren(writer);
        }
    }
