Any error you have encountered? Did objList get populated by your LINQ statement?

Solution 1

Try using this

C#

[System.Web.Services.WebMethod]
public static List<string> GetEmpName(string prefixText, int count)

instead of

C#

[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public static List<string> GetEmpName(string prefixText)
