I looked at using a Datastore but it can only store simple types (strings, booleans,etc.) I want to store an entire object in there and then databind to it from other screens. I...
I'm trying to create a scrolling list of fairly large textblocks. I want there to be a vertical scrollbar to show them all, and if they overflow a certain size I want them to display an ellipsis.

Hey guys, the following tutorial shows how to take the text from a text box and display it in a text block when the user hits a button. Simple enough... but what I want to do is instead of hitting a button that adds the text I want the enter button to do it.

To work around it, I do i...
