How to add text into decision node UML in visual studio 2012

I try to use activity diagram in Visual studio. When I add a decision node to diagram, there is no way to add text to display true or false condition. I searched in connector properties but it doesn't help.
Look at this, I want to add true and false text into decision node:

Another way is using comment node, but the problem is comment doesn't link with connector.
How can I do that? Any help would be greatly appreciated.

Solution

Click on the connector and Right click->Properties. In the Properties you can name the Guard on each connector.
