What does happen is much more important than what does not happen.

Do you have a autocompleteextender control in design which is assigned to that textbox? Something like <pre lang="c#"><asp:AutoCompleteExtender ID="AutoCompleteExtender1"
TargetControlID="txtTextbox" runat="server"
ServiceMethod="names" UseContextKey="True" /></pre>

public string[] names(string prefixText,int count,string contextKey)
{
string sql = "SELECT * FROM familytwo Where Name like @prefixText";
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Connection"].ConnectionString.ToString());
SqlDataAdapter da = new SqlDataAdapter(sql, conn);
da.SelectCommand.Parameters.Add("@prefixText", System.Data.SqlDbType.VarChar, 50).Value = prefixText + "%";
DataTable dt = new DataTable();
da.Fill(dt);
string[] items = new string[dt.Rows.Count];
int i = 0;
foreach (DataRow dr in dt.Rows)
{
items.SetValue(dr["Name"].ToString(), i);
i++;
