I have a page which contains some panels,each panel contains a image and a label with the description of the image. I am trying to display a modal popup when user clicks on any part of the panel. In the modal popup some other details will be displayed but the image will be there.Images will be taken from database.I need to fetch the image id from the panel and need to supply it to the modal popup panel. But the problem is panel does not contain a server side click event. I don't want to post back the entire page on click on the panel. Any suggestion ? Thanks in advance.
