Custom Validator Problem

Hi group, i'm trying to add a customvalidator control to a custom web
control. The problem is i'm getting a "Unable to find control id..."
exception. Here is the code:

public class CuitTextBox : WebControl
protected override void OnInit(EventArgs e)

protected override void OnPreRender(EventArgs e)
Control numericTextBox =

TextBox underliyingText =
numericTextBox.FindControl("txtTextBox") as TextBox;
CustomValidator validator = new CustomValidator();

validator.ControlToValidate = underliyingText.ClientID;
validator.ErrorMessage = "El CUIT ingresado es invalido";
validator.ClientValidationFunction = "ValidateCuit";
validator.Visible = true;
validator.Enabled = true;
validator.EnableClientScript = true;




Thanks in advance for any help
