Hello, thanks to all for the help given. My web page has many nodes. Each of them represents a treeview "expand (i.e., + )" and "collapsed (i.e., -). Therefore, a Collection can be either collapsed or in collapsing state if that Collection is not empty. If users want to collpase a Collection, the application makes a trip to the database to retrieve the elements in that Collection. Each of the node is coded as shown in the attached file (I show one of the Collection(s) I have and I do not want to repeat all of them).
Now, I am trying to introduce a button/link that tells (send a signal to) all those nodes to either expand or not expand. What is the cleverest/cleaninst way to do it? Thanks for your guidance. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
