Update Panel For Label Control

Sir,

working on .net framework 3.5 with vb

I have displayed 50% of text on label control..then i have given a dynamic link to Read More.

when i clicks on Read More it passes query string of id of that content to same page which shows full content.

Now, what I want is when I clicks on Read More link the page postback then loads the full content. So, is there any way to avoid postback using update Panel for any links generated dynamically on Label control.....?
