Whoops...Sorry, must have missed that when I looked through your code...

Did you try removing AutoEventWireup?

awesome, for some reason its working now, lol, it when I changed " to ' around the values, this is working:
Code:
<asp:LinkButton ID="lb_Change" CommandName="change_Feature" CommandArgument='<%#Databinder.Eval(Container.DataItem, "ISBN13")%>' runat="server" Text='<%#Databinder.Eval(Container.DataItem, "rm_TL")%>' />
or because I used Databinder.Eval?
have a look: --Pearson Education--
but I guess this is actually doing a repost of the page? Thought I would be able to do it without it posting? Or is it just my imagination?

Yes, I've had similar issues with double quotes when inside a repeater, but normally it throws an exception.

In order to not do a full postback you need to use an ajax update panel, which allows asynchronous postbacks or a webservice that also uses ajax.

Let me know if you need more info on either....I'm a fan of webservices (.asmx) which can be called from a JS function and then return an object to another JS function that can render to the screen. Obviously you need a fairly good grasp of JS for this. The update panel sorts all that out for you...

Sorry. If I was you, probably just stick to the update panel...It's pretty easy to follow. Try the www.asp.net ajax tutorials.

Just for the lurkers following this thread, this was the problem:
CommandArgument="<%#Container.DataItem("ISBN13")%> "
The function Container.DataItem takes a String argument, so the double quotes around the ISBN13 is correct -- however, this double quote also terminates the string <%#Container.DataItem(. Thus, when using DataItem (or Eval) you should always use single quotes around the argument,
CommandArgument='<%#Container.DataItem("ISBN13")%> '
