Ajax AsyncFileUpload control example in asp.net to upload files to server
First create one new
website after that right click on it add new folder and give name as ‘Files’
after that add AjaxControlToolkit
reference 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"
%>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
// 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>
<form id="form1"
runat="server">
<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 />
<asp:Image ID="imgLoad"
runat="server"
ImageUrl="loading.gif"
/>
<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 properties of Ajax fileupload control
OnClientUploadComplete – This property is
used to execute the client side JavaScript function after file successfully
uploaded.
OnClientUploadError – This property is
used to execute the client side JavaScript function if file uploading failed.
OnClientUploadStarted – This property is
used to execute the client side JavaScript function whenver file uploading start.
CompleteBackColor – This property is
used to set fileupload control background after file upload complete its
default value ‘Lime’.
ErrorBackColor – This property is
used to set fileupload control background if file upload failed its default value
‘Red’.
UploadingBackColor – This property is the id of the control which is seen
during upload file.
UploaderStyle
–
This property is used to set fileupload control appearance style either Modern or Traditional. By default its
value "Traditional".
ThrobberID – ID of control that
is shown while the file is uploading.
Width
–
This property is used to set width of the control. By default its value ‘355px’
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
