HI Harm,

I noticed that with release 2.2 you could also use expressions. From the docs it is not 100% clear to me how to use these. The release notes are showing 4 different ways to use the expression syntax. In what part of the grid/list control do I have to specify the expression? The header, display or edit part? May be a real life piece of source code would clarify my question?

I tried to get this to work in my first AJAX project and noticed that only when a row becomes active the expression value is displayed, otherwise "undefined" is displayed. I must be doing something wrong
