AutoCompleteExtender没有在简单的Web应用程序中调用Web服务 [英] AutoCompleteExtender is not invoking webservice in a simple web application

问题描述

大家好，

我在Web解决方案中使用AjaxControlToolkit.

我在AjaxEnabled Web应用程序中使用了AutocompleteExtender控件，它可以工作，但是同一代码不适用于简单的应用程序.我也已经灌入了所有必需的dll.

我的aspx页面的代码:

<％@页面语言="C#" AutoEventWireup ="true" CodeFile ="Default.aspx.cs" Inherits ="_ Default"％>

< asp:scriptmanager id ="ScriptManager1" runat ="server">

< asp:servicereference path ="AutoComplete.asmx">

Hi All,

I am using AjaxControlToolkit in my web solution.

I used AutocompleteExtender control in a AjaxEnabled web app and it worked but the same code is not working for a simple application. I have inculded all the required dll''s as well.

code for my aspx page :

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>



<title>Untitled Page



<asp:scriptmanager id="ScriptManager1" runat="server">
<services>
<asp:servicereference path="AutoComplete.asmx">

< asp:textbox runat ="server" id ="myTextBox" width ="300" autocomplete ="off">
< ajaxtoolkit:自动完成扩展器

字符串str =//sql连接字符串
SqlConnection conn =新的SqlConnection(str);
SqlCommand cmd =新的SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = conn;
cmd.CommandText ="Ajax_GetCustomerList";

cmd.Parameters.Add("@ customerNameSubString"，SqlDbType.VarChar，100).Value = prefixText.ToString();

SqlDataAdapter da =新的SqlDataAdapter(cmd);
DataSet ds = new DataSet();

int i = 0;
foreach(ds.Tables [0] .Rows中的DataRow dr)
