How to Upload image using FileUpload control without postback

I have a FileUpload control and 2 butons i.e. save and delete along with 1 Image control in asp.net.

User chooses 'any image' using FileUpload control, click of save button, the uploaded image shall display inside Image control, without page postback.

after using UpdatePanel also the aspx page is posted back which is not my requirement. 

There are different sections(tabs) in this aspx page, the current implementation is done for tab 4, so when the page is posted back on click of upload button, the page is landed at tab 1, and again user has to click on tab 4 to see the uploaded image.... but as per the requirement after upload, user shall see the uploaded image instantly being in the same tab (tab 4)

Kinldy help me how to achieve above requirement please.

Thank you so much in advance.

Waiting for the kind reply.

Thank you in advance.
