Update an image control as soon as a file is selected in File Upload control in ASP.NET

I have an image control and a file upload control in .NET 2.0 (VS.NET 2008) form. As soon as user selects an image file in the file upload control, i want the image to appear in the image control of the form. What would be the way to do this ?

(The only event File Upload seems to support is 'OnChange' and i don't know enough javascript to update Image1.URL based on content of FileUpload).

Thanks, Chak.

  • You need to upload Asynchronously , and you could try AJAX AsyncFileUpload and this is what you are looking... http://asp.net-informations.com/ajax/ajax-AsyncFileUpload.htm
