You have bound the single value of the 1st row of the DB to the rawValue of your DDList. You
need to bind to the List Items property instead. Highlight the DDList you want to bind to and on the Object/palette choose the Field tab. In the top right corner of that palette is an icon that you can activate by clicking on it (see the screen shot below):
A menu will pop up and you must select the "Show Dynamic Properties" option to make sure that it is checked on. Now other properties in the UI will become links (you see it underlined and in green on my image). Click on the "List Items" and a wizard screen will pop up and allow you to choose the Data Connection that you want and also bind the column that you want to the Item Text and the Item Value.
Now when you render the DataConenction will get all records and extract the values to put into the DDList.
