I think that the ASP.NET data-binding expressions () are just great. They're simple, powerful, intellisensed and checked at compile time. They reduce everyday coding efforts but do not pollute presentation with any heavy logic.

The most popular use of expressions is the definition of template contents. Repeater and GridView are the controls where I see most often.

But there are some problems with using these expressions within templates. The most interesting thing to databind within a template is the data item of the row template is instantiated in.

This data item is accessible through the IDataItemContainer interface that is implemented by each RepeaterItem and GridViewRow. Within the template expressions, a container is available as a Container variable or through the Eval/Bind pseudo-functions.
