I am working on this problem for two weeks and i cant solve it!
I have even consulted with the people who developed the lightbox i am using.
I have tried your solution
protected void listImages_PageIndexChanged(object sender, RadListViewPageChangedEventArgs e)
Page.ClientScript.RegisterStartupScript(this.GetType(), "yoxview", "loadYOX();", true);
and many other solutions but nothing seems to work. I have spent more time solving this problem than developing the web.
