I have a news section of the website contained within the updatepanel.
What I want is that when a news summary is clicked, the news item
opens up in that same box. I thought I wired everything up correctly
so that it did not do a postback. But when I walked through the
execution process, it in fact does cause a postback when the "expand"
event is raised. Why does this happen? Can someone help me? Thanks.
Here is the .aspx part
