>I'm drawing a blank on this feature where like a textbox or some other text control has too much text and by setting this magical control property it looks like a tooltiptext by extending the text display beyond the control?

This is automatic in grids, but I don't know of a property that makes that happen for other controls. In reports, there's a way to get an ellipsis (three dots) after a fields that's too long.
