turn graphic on/off with c# codebehind
Posted on 2010-01-08
I have an aspx page in c# 2008.
I have a combo box and a list box.
when the combo box selection changes, the listbox gets loaded with values from the server.
I am doing partial updates using update panel with a post-back trigger tied to the combo box.
I want to add a graphic, which is just a small animated gif, which would be visible while the list box is being loaded (which can take some time).
any help appreciated
