I started out using Render, but at some point I started using RenderControl, which I now use exclusively. If I'm forming a bad habit I'd like to nip it in the bud now before I get set in my ways. ...

I'm aware I need to set up the class with these 2 flags: [Par...

Hi, I have a WebControl library I'm using to render out our stylized form elements. The library also contains some overriden validators, so that when used together, I can render out some nicer validation HTML/CSS than the default validator's red-star-next-to-a-field.
