About the requiredfieldvalidator control

Hi, I have a txt box and a button in a webpart/server control.  I also have a requiredfieldvalidator control.  When I click the button I want to call the requiredfieldvalidators.validate() function.  However, before I do this I need to set the controltovalidate property to the controlid of the textbox.  This is not working.  I have tried setting the id property of the textbox to "textbox" and then setting the controltovalidate property to textbox.ID.  When I do this and call validate() an exception is thrown stating that the reference is not set to an instance of an object.  I think I am passing in the wrong id to the controltovalidate property.
Can you help?

Did you set the controltovalidate property  in the designer or in the code behind? Are you using VS 2005?

I set the controlvalidate property in the code behind.  I don't have access to the designer as I'm designing sharepoint web parts.  At least I don't think I do.  I'm a bit new to this.  I'm using VS2008.
I set the requiredfieldvalidator validator = new requiredfieldvalidator in the createchildcontrols() method.  I set the ID of the text box to a string eg theTextBox.ID = "thetextbox" and the textbox is set to a new instance in createchildcontrols() and yet I'm still getting the object not set to an instance exception.

Well, I am no expert in SharePoint development. I got this question because it is labeled in ASP.NET zone. You may need to add SharePoint zone in your question so experts in that zone will be able to see this question and give you solution.
