Question

我有一个文本框，它应该根据我连接的数据库自动完成。以下代码在webforms中工作得非常好。下面是html代码：

   <%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage2.master" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %>
   <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
   <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <html xmlns="http://www.w3.org/1999/xhtml">
    <body>

  <ajax:ToolkitScriptManager ID="ScriptManager1" runat="server"/>
  <div>
  <asp:TextBox ID="txtCategory" runat="server"></asp:TextBox>
  <ajax:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" TargetControlID="txtCategory" MinimumPrefixLength="1" EnableCaching="true" CompletionSetCount="1" CompletionInterval="1000" ServiceMethod="GetCategories" >
  </ajax:AutoCompleteExtender> 
  </div>
  </body>
  </html>
  </asp:Content>

以下是相同的代码隐藏：

  public partial class test : System.Web.UI.Page
  {
  protected void Page_Load(object sender, EventArgs e)
  {

  }
[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public static List<string> GetCategories(string prefixText)
{
    string CS = ConfigurationManager.ConnectionStrings["IS"].ConnectionString;
    using (SqlConnection con = new SqlConnection(CS))
    {
        con.Open();
        SqlCommand cmd = new SqlCommand("select * from tblAllRegisteredBusiness where SubCategory1 like @Name+'%'", con);
        cmd.Parameters.AddWithValue("@Name", prefixText);
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataTable dt = new DataTable();
        da.Fill(dt);
        List<string> AllCategories = new List<string>();
        for (int i = 0; i < dt.Rows.Count; i++)
        {
            AllCategories.Add(dt.Rows[i][13].ToString());
        }
        return AllCategories;
      }
    }
  }

但是上面的代码在masterpage中不起作用。我需要添加一些东西吗？

使用ajax在母版页中无法自动完成
