Question : How to generate a page postback with ajax?

I have a link button inside a gridview, which is inside an update panel (updResults).  When I click on the linkbutton, I want to update labels placed in another update panel (updDetails).
Obviously, clicking the link button does not cause a postback.  I think maybe I outta use ScriptManager.RegisterStartupScript or the Trigger tag of the updatePanel.... but I don't quite understand how to do it.

Can anybody help me?

Answer : How to generate a page postback with ajax?

since the link button has a CommandName , the gridview could be set as the AsyncPostBackTrigger of "another update panel "

you could try something like this at first, and if it work,  try to add a EventName (like EventName="ItemCommand" ) but you could skip that if ther is no other event on the grid.
