自动完成AJAX不工作 [英] AutoComplete AJAX Not Working
问题描述
我使用的是 AutoCompleteExtender 从AjaxControlToolkit在文本框。
I am using an AutoCompleteExtender from AjaxControlToolkit on a TextBox.
要简单地说，当我拖上我的文本框掉落 AutoCompleteExtender 工具，然后单击添加自动完成页面的方法，我得到以下错误：
To put it simply, when I drag and drop the AutoCompleteExtender tool on to my TextBox and then click on "Add AutoComplete page method", I get the following error:
无法创建页面的方法GetCompletionlist因为没有codeBehind或
codeFILE被发现！
Cannot create page method "GetCompletionlist because no CodeBehind or CodeFile was found!
谷歌搜索错误后，我基本上是做了我自己的Web服务被称为AutoCompelte.asmx。下面是code该类：
After googling the error, I basically made my own web-service called AutoCompelte.asmx. Below is the code for that class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
namespace AutoCompleteTest
{
/// <summary>
/// Summary description for AutoComplete
/// </summary>
[WebService(Namespace = "http://microsoft.com/webservices/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
[System.Web.Script.Services.ScriptService]
public class AutoComplete : System.Web.Services.WebService
{
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetCompletionList(string prefixText, int count, string contextKey)
{
// Create array of movies
string[] movies = { "Star Wars", "Star Trek", "Superman", "Memento", "Shrek", "Shrek II" };
// Return matching movies
return (from m in movies where m.StartsWith(prefixText, StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray();
}
}
}
当然，上面是伪数据....后来，我从数据库中获取数据。
Of course, the above is dummy data.... Later on, I shall be getting the data from a database.
和我Default.aspx的是这样的：
And my Default.aspx looks like this:
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
From
<asp:TextBox ID="txtFrom" runat="server">
</asp:TextBox>
<asp:AutoCompleteExtender runat="server"
ID="txtFrom_AutoCompleteExtender"
TargetControlID="txtFrom"
ServiceMethod="GetCompletionList"
ServicePath="AutoComplete.asmx"
MinimumPrefixLength="2"
CompletionInterval="1000"
EnableCaching="true"
CompletionSetCount="20"
DelimiterCharacters=";, :"
ShowOnlyCurrentWordInCompletionListItem="true">
</asp:AutoCompleteExtender>
当我运行的网站....并输入文本框，什么都不会发生。没有扩展所示。即使我输入明星。
When I run the website....and type in the textbox, nothing happens. No Extender is shown. Even if I type "Star".
我是什么失踪，为什么我收到这个错误开头？
What am I missing and why was I getting that error at the beginning?
P.S。我在我的大学电脑，所以，我认为错误可能是由于我使用的网络类型。不知道。
P.S. I am on my University computers so, I think that error might be due to the type of network i am using. not sure.
任何帮助是非常HIGHLY HIGHLY AP preciated !!
Any help is HIGHLY HIGHLY HIGHLY appreciated!!
感谢。
推荐答案
我得到了它的工作。这是我如何固定它：
I got it working. This is how I fixed it:
我的项目是一个应用程序的网站在Visual Studio中。当我只是做了一个网站项目，它的所有工作完美....我不知道为什么，它只是做了。
My project was a "Website Application" in Visual Studio. When I simply made a "Website" project, it all worked perfectly.... I don't know why, it just did.
因此，如果其他人是否有相同的问题，尝试端口code到一个网站项目，而不是一个网站应用程序项目。
So if anyone else is having the same problem, try port the code over to a "Website" project rather than a "Website Application" project.
