I have a aspx page that ask user to enter firstname, last name and upload an image.
I am calling ajax [WebMethod] on a .cs file through jquery to save form data on sql database. However, I am unable to access the FileUpload control.
How can I upload an image and send its bytes?

Sorry, "I'm unable" is not informative. The uploading of files is demonstrated in huge number of articles and answers.

You can't use ajax to upload files. You'll need to use the html5 file api to do this (the browser needs to support html5 though) or use an asynch file upload script. Google for examples of asynch file uploads and you'll find lots of examples.

There are many, many examples online. Just google for them and you'll see.

You cant use Asp controls in ajax call. however you can use ajax uploader.
