Difference between commandLink, ActionSupport and actionFunction
Hi folks,
Could anyone plz explain me the exact difference b/w,
commandLink,
actionSupport and
actionFunction
With some scenarios.
When to use them perticularly, in which scenarios.
It is confusing a lot between the 3.
I know them individually,

I know them individually,
Commandlink:
A link that executes an action defined by a controller, and then either refreshes the current page, or navigates to a different page based on the PageReference variable that is returned by the action. An <apex:commandLink>component must always be a child of an <apex:form> component.
Action Support:
A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover.
Action Link:
A component that provides support for invoking controller action methods directly from JavaScript code using an AJAX request. An <apex:actionFunction> component must be a child of an <apex:form> component.
Please check out the below link s for examples and scenarios on all the above apex methods.
