does not contain a definition for controls

I get this build error
does not contain a definition for controls
here is my code...

//XML HEADER
XMLWriter.Formatting = Formatting.Indented;
XMLWriter.WriteStartDocument(true);
XMLWriter.WriteStartElement("ConditionReport");
//XML DETAIL
//LOOP THROUGH FORM ITEMS AND WRITE TO XML
foreach (Control C in this.Controls)

Thank you,

re: does not contain a definition for controls

"this" does not have a Controls property
