A Hyperlink just redirects to a GIVEN URL identified by "NavigateURL" property.
LINK Button does not have Navigate URL INSTEAD it has “Postback URL” property
LinkButton causes a postback to the same page but it doesn't redirect to a given URL
HyperLink doesn't have the OnClick event. Link Button has Onclick event
if you need to do any operation with data that's on the page you will have to use a LinkButton (or a Button), but if you just need to redirect the USER to somewhere else go for an HyperLink
