Regarding Ajax AutoComplete Extender

Question

 Hi All,

I have created a small web application using ajax autocomplete extender. I have used VS2008 C# and oracle db. In oracle db table I have ten records starting with the letter 'a'. I have achieved the autocomplete function; I mean when I typed letter a in the textbox it came up with popup showing all ten values as all start with letter a. This is fine. But what I want is "Value Concatination". I mean suppose first I type a it will show the popup and I select the first value say 'Apple' now what I want is if I type space after I select the value the same pop up should appear and if I select the second value say 'Ant' it should be concatenated with the first value I selected. i.e; in text box I want Apple Ant. It shouldn't replace the the first value that I had selected. The popup should allow to select the third item and so on. How to achieve this ?

I searched in some forums, the solutions were little lengthy and not that much understandable.

Please help.

Thanks,
Sachi
