RadControls for ASP.NET AJAX  Caution |
|---|
RadUpload has been replaced by RadAsyncUpload, Telerik’s next-generation ASP.NET upload component.
If you are considering Telerik’s Upload control for new development, check out the documentation of RadAsyncUpload or the control’s product page.
If you are already using RadUpload in your projects, you may be interested in reading how easy
the transition to RadAsyncUpload is and how you can benefit from it in this blog post.
The official support for RadUpload will be discontinued in June 2013 (Q2’13), although it will still
be available in the suite. We deeply believe that RadAsyncUpload can better serve your upload needs and
we kindly ask you to transition to it to make sure you take advantage of its support and the new features we constantly add to it.

This article shows how to upload the file automatically upon selection. What we will achieve is to let the user select a file and
submit the form automatically after that. We will use the
OnClientFileSelected event which fires right after the user
selects a file and submit the form.
Here is the RadUpload's declaration:
CopyASPX
<telerik:radupload id="RadUpload1" runat="server" onclientfileselected="submitFile"
targetfolder="uploads">
</telerik:radupload>
<asp:Button ID="Button1" runat="server" Text="Button" Style="visibility: hidden;" />Here I have hidden the submit button by using a style, but this is an option only. Here is the javascript event handler:
CopyJavaScript
function submitFile(sender, e) {
$get("<%= Button1.ClientID %>").click();
}
