How will I use SUGGESTED KEYWORD TOOL SERVICE in my web application?

Question

Hai,

I am working with ASP.NET C# 3.5 web applications. I intergrated MicroSoft AdCenter API 6.0 with my web application for advertisement purpose and this is working fine.

Now, my client expected the KEYWORD SUGGESTION speciality also like real AdCenter WebSite. (i.e. when we make an advertisment directly in the real AdCenter Site, entering keyword also one of the steps. At that time we have 2 options, i.e. either we can enter our own keyword or we can select the suggested keywords from the list).

Currently in my website also I provided screen for enter keywords. But those keywrods are MANUAL ENTER OWN KEYWORDS. Now I need to implement that SUGGESTED KEYWORD SERVICE also with my web application.

Can anybody provide some useful link with example to me. This is some urgent one.

Thanks in advance.
