I will try to address each question in the order they were entered:
- OnLoad methods for all controls - if you are looking for the server OnLoad event, this is a standard event exposed by the Web.UI.WebControls.WebControl class and therefore its documentation is located in the MSDN site and not on ours: http://msdn.microsoft.com/en-us/library/system.web.ui.control.onload(v=vs.110).aspx. If you are looking for a client-side Load event, some controls expose it and some do not. This primarily depends on the control specifics. You can find lists of the available control events in their documentation, for example: http://www.telerik.com/help/aspnet-ajax/window-programming-client-side-events.html. Each control has a Client-side Programming section where its client-side API and events are listed.
- on using RadWindows' ContentTemplate with AJAX - the following article covers the most important factors that need to be taken into account: http://www.telerik.com/help/aspnet-ajax/window-ajaxifying.html.
- the concrete setup - the above article should explain how to properly configure the AJAX setup and interactions on the page. What you need to make sure is to have the contents of the RadWindow as a part of the partial page rendering. If you are using asp;UpdatePanel controls, you may need to call their Update() server method to include them in the response, and if you are using RadAjax, you would need appropriate AJAX settings where the buttons/tree are initiators and update the contents you need.
- on editing posts - this feature is not available at the moment, primarily to avoid confusion. If a post is edited while somebody is attempting to answer it, it will lead to loss of information and confusion. If it is edited at a later stage, it is likely that the thread will become incoherent or unreadable.
I hope this explains the situation and helps you advance with your tasks.
