Hi,
 
I am working with Ajax Autocompleteextender.
 
It is not displaying the names .
 
Below is the sample code.
 
.cs
  1. [System.Web.Script.Services.ScriptMethod()]  
  2. [System.Web.Services.WebMethod]  
  3. public static List<string> Getfirstname(string prefixText)  
  4. {  
  5. string strFilter = string.Empty;  
  6. DataSet ds = new DataSet();  
  7. System.Data.DataTable dt = new System.Data.DataTable();  
  8. es_CustomersDAL ObjCustomersDAL = new es_CustomersDAL();  
  9. ds = ObjCustomersDAL.GetCustomers();  
  10. //ds = (DataSet)HttpContext.Current.Session["dsgroups"];  
  11. System.Data.DataView dv = ds.Tables[0].DefaultView;  
  12. strFilter += "ES_CustomerName LIKE '" + prefixText + "%'";  
  13. dv.RowFilter = strFilter;  
  14. dt = dv.ToTable();  
  15. List<string> GetCustomerName = new List<string>();  
  16. for (int i = 0; i < dv.Count; i++)  
  17. {  
  18. GetCustomerName.Add(dt.Rows[i]["ES_CustomerName"].ToString());  
  19. }  
  20. return GetCustomerName;  
  21. }
