I am glad that you were able to solve the problem yourself and apologize that we could not help you right away.
However, since Q3 2011 RadInput has a new rendering mode
. This mode is controlled through the EnableSingleInputRendering property. Since Q1 2012 it is set to true by default and the RadInput controls use a single input of type text to keep the entered values. Whereas with the non-single input rendering mode, two or three inputs of type text are rendered.
Enabling the single input rendering mode improves the page performance and allows for easier customizations.
