Hello,
I'm trying to create a reusable server control that will act as a "Help control" - it will render an image (or an image button) and will display a rich tooltip after clicking (or hovering) containing some help-related data. Since there can be a lot of content in the tooltip and there can be many of these controls on the page I would like to load the content only on demand - for instance from a Web Service.
I know that RadToolTip itself has no support for loading content from Web Service - I have to use RadToolTipManager or handle loading data on my own and use RadToolTip. What will be the best way (considering the performace and reusability) to achieve this :
1. Each Help control creates a RadToolTipManager for itself
2. Assume that there is one RadToolTipManager (for instance in master page) and use it to display tooltips. (But how to access it since there is no RadToolTipManagerProxy)
3. Each Help control creates an empty RadToolTip for itselft, loads the content from web service on its own and when its loaded uses RadToolTip client side API to fill the tooltip with the content and show it.
Or maybe there is a better solution ?
