I need to upload images using FileUpload without postback(using Ajax).I tried many examples.But in all postback is coming or they are using PHP.Can anyone help me to do sing
There is no way you can access the contents of a file input field through JS. This is because of security concerns. Though what you CAN do is to create an iframe and from a button submit only that iframe which again can contain your file input field...
This would give the "impression" of an Ajax File Upload control...
I use Ajax Uploader too. It works great for my projects and it allows you to upload files to web server without refreshing the page.
Here is a demo page.
