Silverlight 4 : Auto-display tooltips on out of bounds text

I have an item control wherein i display a list of string in rows and columns, the problem is that due to excess amount of text, the text gets cropped. So i wish to implement a tool-tip that can detect the excess text and display the complete text once i hover over the item or perhaps scroll the text once i hover onto it

PS: -i do not want to increase the width of the item cont开发者_如何学Pythonrol or the window -i do not want to wrap the text so it accommodates in a next line.
