Using binding in control attributes
When you use direct binding you specify a bind expression in a ColdFusion form or display control attribute. In the
simplest, form of binding you use form fields, such as a name field, to fill other fields, such as an e-mail field, as the
following example. shows. When you enter a name or domain and tab to click in another field, the name is added to
the e-mail field.
