required field validator in Web custom control

[Sogescom]

I tried to make a control with a label a text box and a
required fiel validator, but i always reiceved this error:

Unable to find control id 'FormField:Address1' referenced
by the 'ControlToValidate' property of ''.

What i'm doing wrong???

this is the to main method

protected override void CreateChildControls()
{
TextBox tbxAddress = new TextBox();
Label lblMessage = new Label();
RequiredFieldValidator req = new RequiredFieldValidator();
lblMessage.Text= "";
Controls.Add(lblMessage);
tbxAddress.ID = "FormField:Address1";
Controls.Add(tbxAddress);
req.ControlToValidate = tbxAddress.ID;
req.ErrorMessage = InvalidMessage ;
Controls.Add(req);

}
protected override void Render(HtmlTextWriter output)
{
EnsureChildControls();
base.Render(output);
}

Try adding the TextBox with such ID that doesn't have ':' . Also did you
implement INamingContainer interface in your control? Implementing it would
be advisable.

Hello,

I replied a same post yesterday. Based on my testing, if you removed
"FormField:" from the ID property of textbox, the code runs fine. It seems
that the problem is caused by colon.

If you have any follow up questions, just post them here.
