Hello Supriya,

Try increasing CompletionSetCount. As per documentation the signature of the Service method should be as shown below.

[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public string[] GetCompletionList(string prefixText, int count)

I will also recommend you to go through this[^] article.

Regards,

Try to test in FireFox. See if you get any errors in Error Console(Ctrl + Shift + J), Or in Script Tab of IE Developers Tool.
