title: asp.net web forms tag property
body: <p>Could somebody tell me if in asp.net web forms is something like <code>Tag</code> property like in windows forms.<br/>
  I want to bind some data to controls that i will be able to identify them later without adding a lot of <code>if(...) { }</code> <br/>
  To be more specific I'd like to use that tag in building sql <code>selectcommand</code> and these tags would be like : <code>c.City, c.Country</code> and it would be binded to <code>checkboxlists</code></p>
