Programmatically adding validation control to asp.net page

I am trying to add a required fields validator programmatically in asp.net. But I get the following error message - Control 'req2' of type 'RequiredFieldValidator' must be placed inside a form tag with runat=server

The c# code i have used is below - 

protected void Page_Load(object sender, EventArgs e)
    {
        RequiredFieldValidator rv = new RequiredFieldValidator();
        rv.ID = "req2";
        rv.ControlToValidate = "TextBox2";
        rv.ErrorMessage = "Data Required";
        this.Controls.Add(rv);
    }

Could someone tell me whats gone wrong here?

Thanks for sharing your valuable time.

Try adding the control to the Form of the page. The reason for this is that you need to add this type of controls to a form. 

this.Form.Controls.Add(rv);
