在AutoCompleteExtender问题中未定义CreateAutoCompleteItem方法 [英] CreateAutoCompleteItem method is not defined in AutoCompleteExtender issue

问题描述

我在aspx页面上使用了ASP.NET 2.0的AjaxControlToolkit的AutoCompleteExtender控件.

该控件工作正常，我正在从数据库中接收值，但是问题是我无法在控件中获取选择值的键.我听说CompleteAutoCompletionItem(key，value)方法可以为控件提供键和值.

当我使用此代码时:

Hi,

I am using AutoCompleteExtender control of AjaxControlToolkit for ASP.NET 2.0 on my aspx page.

This control is working fine and I am receiving values from the database but the problem is that I am unable to get the key for select value in the control. I heard that CompleteAutoCompletionItem(key,value) method can provide keys and value to the control.

When I use this code:

AjaxControlToolkit.AutoCompleteExtender.CreateAutoCompleteItem(key,value)

我收到一条错误消息，指出未在AutoCompleteExtender控件中定义CreateAutoCompleteItem方法".

任何帮助将不胜感激.提前谢谢！

问候，
Divya

I get an error stating "CreateAutoCompleteItem method is not defined in AutoCompleteExtender control".

Any help will be appreciated. Thanks in advance!

First[^] google hit.

Not being able to see your code, it''s hard to know what it looks like. Does it look like this sample ? What is the exact error ?

我已经浏览了您粘贴的链接.从那里本身，我得到了这个方法的名称.

我的Web服务的代码(截至目前，该字符串将字符串数组返回给AutoCompleteExtender)是:

Hi,

I had gone through the link you pasted. From there itself, I got this method name.

Code for my web service which is returning a string array as of now to AutoCompleteExtender is:

using System;
using System.Collections.Generic;
using System.Web.Services;
using System.Data.SqlClient;
using System.Data;
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class AutoComplete : WebService
{
public AutoComplete()
{
}
[WebMethod]
public string[] GetCompletionList(string prefixText, int count)
{
string str = // sql connection string
SqlConnection conn = new SqlConnection(str);
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = conn;
cmd.CommandText = "Ajax_GetCustomerList";
cmd.Parameters.Add("@customerNameSubString", SqlDbType.VarChar,100).Value = prefixText.ToString();
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds, "customerSubStringList");
string[]chk = new string[ds.Tables[0].Rows.Count];
int i = 0;

ArrayList list = new ArrayList();

foreach (DataRow dr in ds.Tables[0].Rows)
{
chk[i] = dr[0].ToString();
i++;

//list.Add(AjaxControlToolkit.AutoCompleteExtender.CreateAutoCompleteItem(dr[1].ToString(),dr[0].ToString())); /* This line I added to get the key, value pair */

}
return chk;
}

}

请协助.谢谢！

Please assist. Thanks!

确切的错误是:

"AjaxControlToolkit.AutoCompleteExtender不包含"CreateAutoCompletionItem"的定义".

The exact error is :

"AjaxControlToolkit.AutoCompleteExtender does not contain a definition for ''CreateAutoCompletionItem''"
