Couple of weeks ago I saw the reviews for an app in the Windows Store and noticed that if the review is longer than x characters it shows a hyperlinkbutton with the text “Show more”.

When you click it the review is shown with the full text of the review. This week I was working on an app where I needed this functionality. Not exactly with the text not fitting anymore, but showing some more details when the user clicks on the gridviewitem. I decided to try to build it exactly like in the Windows Store.
