Hi, this is my first time posting here. I first want to say what an invaluable resource your book has been for me, Imar. I couldn't have asked for a more clear, concise, and understandable book.

Anyway, here is my question.

Along with the sample website I'm creating from the book, I'm also working on my own site as I read through the chapters. It uses a master page and contains a header, a menu, a sidebar and a main content area. When any link in the header, menu or sidebar is clicked, the site posts back and the main content area changes (header/menu/sidebar look the same due to the master page). Ok. What I want to be able to do is apply an updatepanel so that when a user clicks a link, ONLY the main content area posts back and refreshes. In Chapter 10 you explain how the updatepanel can be refreshed with controls encased inside of it, or by use of triggers from other controls. But is it possible to trigger the updatepanel with links (such as clicking on the banner image in the header) rather than server controls?

Thanks for your time,

-Chris

Hi Chris,

Yes, you can use LinkButtons for that. They render as standard links, but use JavaScript to do a postback.

However, it depends on where you want to use them. If you request a new page (e.g. when you go from Home to Reviews) you can't use UpdatePanels. Check out my last post in this thread for more details: Full reload of page

Cheers,

Imar

Thank you, that helps me understand. I will explore LinkButtons and see what I can figure out!
