This is because the Rad Ajax Panel AJAX-enables that control instead of the Rad Ajax Manager.
Rad Ajax Panel is designed to update only its content;therefore you cannot use the manager to update other controls outside of the panel from a control that has been AJAXfied by the manager but is inside the Rad Ajax Panel. Example 1: Button1 on the Rad Ajax Manager won't update the label because the Rad Ajax Panel only updates its own content.
In your code, you have kept all the controls in the same Rad Ajax Panel, In my scenario both the grids are on different Rad Ajax Panel.
If the same control is placed in a Rad Ajax Panel as well as included in Rad Ajax Manager settings as an AJAXified control (i.e., it is AJAXified by both the Rad Ajax Panel and Rad Ajax Manager),the Rad Ajax Manager's setting will not work.

The First Button changes the text of Lable1 to Hi and Second button changes the Label2 to Bye without loading the whole page.
