I have a page with a panel (pnlA), a radcombobox and a usercontrol. I have added ajaxsettings which allow the radcombobox to update the panel using ajax. I would like for the controls in the usercontrol to also update the panel. I have tried to add ajaxsettings so that the usercontrol itself is the ajaxified control. I have also tried wrapping the user control in a panel and using this container panel as the ajaxified control. I have tried wrapping the controls in the usercontrol in a panel and then exposing this panel as a property of the user control, and then setting this as the ajaxified control. Lastly, I have tried exposing the individual controls as properties of the usercontrol, and then setting these as the ajaxifiedcontrols. None of these seems to allow the controls within the user control to update the original panel (pnlA) in my page. How can I do this?
