I need to get the context value in top of page, where the context value will be set at the bottom of the page.
- Get context value ==> "empty", BUT need "something"
- Set context value to "something"
- Get context value ==> "something"
I may use JS/AJAX, where the page source the value won't be present.
BUT I need the TEXT in the View Source of the page too.
Is there a way to wait for the context to set and then get, I have tried with User Control, prerender and render methods too. But I can't able to get it right.
Any idea?
