How can I use AjaxFileUpLoad control? [migrated]
- by DWHelper
Now I'm using Visual Studio 2013 and I imported the AJAX Toolkit downloaded from Microsoft specific site successfully and drag and drop AjaxFileUpLoad control into my page form, and the generated codes are:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="CSharp.WebForm1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajaxToolkit:ToolkitScriptManager>
<ajaxToolkit:AjaxFileUpload ID="AjaxFileUpload1" runat="server"
MaximumNumberOfFiles="5" AllowedFileTypes="jpg"/>
</div>
</form>
But the question is that I can run the page properly, click the black "Submit" button and upload a file, but it occurs an error……Why?
