>I have a web I am currently working on that I have published a first pass on. One of my pages contains a control which displays bio content along with a photograph. Both the bio content and the photo come from a SQL Server 2008 database. If there is no photo available, a placeholder photo is displayed. The problem is when you click on one bio name you see the photo but when you click on another the photo doesn't change. However if you click on a name which does not have a photo it changes to the placeholder. Once you get that, you can click back on a name with a photo and get it. I am struggling to see what is causing this behavior. I am posting some of my code if someone else sees why that might happen. The bio content portion always is displayed properly. Both the photo and the bio are on the same control.

One issue - if the entity doesn't have any values, you're not setting the image to anything.

It looks like you might be using Telerik's controls for this. If you're using their Ajax control you need to make sure that the treeview is set-up to update the image control (if you go into the Ajax builder you would select the treeview control on the left of the builder and the image control on the right). If you don't do that it won't automatically refresh.
