Something I'm finding very limiting is that the Ext.Net Controls is not having any common base class or interface. I'm having to write simple support functions for every control just to set common properties.

What would be nice is a nice set of interfaces that all basic controls subscribe to for common properties like text, html, class, visible, tooltips, etc. MS has the WebControl base class but obviously that's not going to work here, so that's why I'm proposing interfaces.

Obviously some thought would need to go into this, but it seems to me that a simple grid of all ext.net controls and their properties/methods on the horizontal, would expose the majority intution for groups of interfaces.

No control library is really complete without some sense of common bases.
