Updating placeholder control on master page from child in codebehind?

[DH]

I'm having an issue trying to update an ajaxpanel that contains a placeholder on a master page from the child page. 

In my master page, i expose the panel to the child page. The panel is wrapped in an ajaxpanel.

In the child page, I may have a button that does some function within its own ajaxpanel, the codebehind for that button will change the panel in the parent page, however the ajax panel on the parent page does not update.

Is there a better way to to do this?

My end result is to have a set of status-notifications (error, success, info, etc) on the master page that can easily be called from child pages within the application without the need for client-side scripting.

Hello Dan,

Note that when implementing Ajax functionality in Master/Content Page application as well as in case if UserControl usage we always recommend using RadAjaxManager control as it provides more flexible way for adding Ajax setting across the different pages.

See the help topics below for more information  on this matter:
