I will explain how to use ajax AsyncFileUpload control to upload files to folder in asp.net. Before proceed to implement sample have you install ajaxcontroltoolkit in visual studio or not if not install it otherwise if you already done then follow the below steps to implement Ajax AsyncFileUpload control example in asp.net.

First create one new website after that right click on it add new folder and give name as ‘Files’ after that add AjaxControlToolkitreference to your application and add following line in your aspx page

<%@ Register Namespace="AjaxControlToolkit"Assembly="AjaxControlToolkit"tagPrefix="ajax"%>

Once add above references design your aspx page will be likes this

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>

<title>Untitled Page</title>

// This function will execute after file uploaded successfully

function uploadComplete() {

document.getElementById('<%=lblMsg.ClientID %>').innerHTML = "File Uploaded Successfully";

}

// This function will execute if file upload fails

function uploadError() {

document.getElementById('<%=lblMsg.ClientID %>').innerHTML = "File upload Failed.";

}

</script>

</head>

<body>

<ajax:ToolkitScriptManager ID="scriptManager1" runat="server"/>

<div>

<ajax:AsyncFileUpload ID="fileUpload1" OnClientUploadComplete="uploadComplete" OnClientUploadError="uploadError"

CompleteBackColor="White" Width="350px" runat="server" UploaderStyle="Modern" UploadingBackColor="#CCFFFF"

ThrobberID="imgLoad" OnUploadedComplete="fileUploadComplete" /><br />

<br />

<asp:Label ID="lblMsg" runat="server" Text=""></asp:Label>

</div>

</form>

</body>

</html>

If you observe above code I define lot of properties to ajax:AsyncFileUpload now I will explain all the

Now in code behind add following namespaces

C# Code

using System;

using System.Web.UI;

using AjaxControlToolkit;

After completion of adding namespaces write following code in code behind

protected void fileUploadComplete(object sender, AsyncFileUploadEventArgs e)

{

string filename = System.IO.Path.GetFileName(fileUpload1.FileName);

fileUpload1.SaveAs(Server.MapPath("Files/") + filename);

}

VB Code

Imports System.Web.UI

Imports AjaxControlToolkit

Partial Class Default

Inherits System.Web.UI.Page

Protected Sub fileUploadComplete(ByVal sender As Object, ByVal e As AsyncFileUploadEventArgs)

Dim filename As String = System.IO.Path.GetFileName(fileUpload1.FileName)

fileUpload1.SaveAs(Server.MapPath("Files/") & filename)

End Sub

End Class

How Install Ajax in visual studio?

1) First step is to download the latest version of the Ajax Control Toolkit from CodePlex whichever suits to your visual studio. If you are using Visual Studio 2008 then you should pick the version of the Ajax Control Toolkit for .NET 3.5. If you are using Visual Studio 2010 then you can use either the .NET 4 or .NET 3.5 versions of the Ajax Control Toolkit.
