Instead of button use timers to update update panels by calling function on timer tick.

Avoid timers if you can, they'll update the panel whether you need it or not and could update in the middle of users input. Buttons or textbox events are fine. There are plenty of examples that are easily googled.

set the update mode to conditional.

C#

<asp:updatepanel id=""UpdatePanel1"<br" mode="hold" xmlns:asp="#unknown" />                  UpdateMode="Conditional"
                  runat="server">

and on the button click write the code when ever you want to update the UpdatePanel

C#

UpdatePanel1.Update();
