Question

我尝试使用Ajax autoCompleteExtender在我的代码后面使用sql查询自动完成我的文本框。我遇到的问题是我的代码背后根本没有被击中。

相反，我的自动填充选项显示为我的母版页中的代码。

我做过一些研究，问题可能是我的文本框是在我的aspx文件中调用的ascx文件中，但我无法找到解决方法。我甚至尝试将ServicePath指向webService，它仍然没有被击中。

任何输入都会有所帮助，谢谢！

这是我的相关代码：

Aspx文件：

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage/Admin.Master" AutoEventWireup="true" EnableEventValidation="false" %>
<%@ Register TagPrefix="AdminSearch" TagName="AdminSearch" Src="AdminSearch.ascx" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<AdminSearch:AdminSearch runat="server" ID="AdminSearch" />
</asp:Content>

Ascx文件：

<%@ Control Language="C#" ClassName="WebUserControl" AutoEventWireup="true" EnableViewState="true" Inherits="AdminSearch" CodeBehind="AdminSearch.ascx.cs" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

<link href="../Style/Search/AdminSearch.css" rel="stylesheet" />
<script src="../Scripts/js/Search/AdminSearch.js"></script>

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods = "true">
</asp:ScriptManager>

<td class="g3">
        <br />
        <asp:TextBox ID="TextBoxTierProfile" CssClass="g3" runat="server"></asp:TextBox><br />
        <cc1:AutoCompleteExtender ServiceMethod="SearchProfiles" ServicePath="~/AutoComplete.asmx"
            MinimumPrefixLength="2"
            CompletionInterval="1" EnableCaching="true" CompletionSetCount="10"
            TargetControlID="TextBoxTierProfile" 
            ID="AutoCompleteExtender2" runat="server" FirstRowSelected="false">
        </cc1:AutoCompleteExtender>
    </td>

Asmx文件：

                    {
                        while (sdr.Read())
                        {
                            profiles.Add(sdr["PROFILENAME"].ToString());
                        }

                    conn.Close();
                    return profiles.ToArray();
                }
            }
        }
    }
}

Ajax AutoCompleteExtender没有在userControl C＃中遇到代码
