我正在尝试从数据库创建搜索。当用户开始在文本框中输入时，城镇列表会出现在带有自动完成扩展程序的文本框下方。它在普通网页中工作正常，但如果我将代码放在母版页中，它就无法工作。 “GetList”不是事件触发。有什么建议么？谢谢。
母版页代码:
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Master.master.cs" Inherits="Obelo.MasterPages.Master1" %>
<%@ Register TagPrefix="asp" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit"%>

SqlCommand cmd = new SqlCommand("select * from tblTowns where Name like @Name+'%'", con);
cmd.Parameters.AddWithValue("@Name", prefixText);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
List<string> CountyNames = new List<string>();
for (int i = 0; i < dt.Rows.Count; i++)
{
CountyNames.Add(dt.Rows[i][1].ToString());
}
con.Close();
return CountyNames;
}
}
}
最佳答案
根据文档，服务方法的签名必须是:
public string[] GetCompletionList(string prefixText, int count, string contextKey)
{
...
}
