c# - ASP.NET 中的 Ajax 自动完成文本框在母版页中不起作用

Question

此示例适用于普通的 asp.net 页面。但与母版页一起使用时，它不起作用。

ma​​sterpage.master

 <asp:TextBox ID="TextBoxSearchCompany" class="form-control" placeholder="Search company..." runat="server"/>
                         <asp:AutoCompleteExtender ID="txtName_AutoCompleteExtender" runat="server" DelimiterCharacters="" Enabled="True" ServiceMethod="GetCompletionList" 
                            ServicePath="" TargetControlID="TextBoxSearchCompany" UseContextKey="True" MinimumPrefixLength="2" CompletionInterval="10" EnableCaching="true" CompletionSetCount="3">
                        </asp:AutoCompleteExtender>

母版页代码背后

        [System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
    public static string[] GetCompletionList(string prefixText, int count, string contextKey)
    {
        string connectionString = ConnectionString.GetConStr();
        SqlConnection conn = new SqlConnection(connectionString);
        // Try to use parameterized inline query/sp to protect sql injection
        SqlCommand cmd = new SqlCommand("SELECT TOP " + count + " company FROM [vwCompanyLookup] WHERE company LIKE '" + prefixText + "%'", conn);
        SqlDataReader oReader;
        conn.Open();
        List<string> CompletionSet = new List<string>();
        oReader = cmd.ExecuteReader(CommandBehavior.CloseConnection);
        while (oReader.Read())
            CompletionSet.Add(oReader["company"].ToString());
        return CompletionSet.ToArray();
    }

解决这个问题的任何帮助。

在服务路径中输入服务名称 --> GetCompletionList
