I am trying to run some code when a node is checked (specifically recursively checking child nodes)

BUt when I run the code nothign happens..I am using teh TreeView1_TreeNodeCheckChanged event handler and it is wired into the control..but it never runs the code...debugging stops dont ever get fired.

DOes this event only run on postback or something?

Should I be using a diferent event handler?

You are correct.  You can catch this event only after postback.  You may try using the SelectedNodeChanged event.  It is fired when user clicks on the node.

Does checking a node cause the SelectedNodeChanged event to fire?

Do you mean you can allow users to check one item only?  If so, treeview seems to be not suitable for you.  Can you use radiobuttonlist?

no its not a single selection. I need child nodes to be checked when the parent node is checked and parent node to uncheck when a child node is unchecked. I have the code to do this but the only event handler that deals with the check boxes is the checkchanged EH...seems kind of retarded to me that the treeview doesnt have a means of firing and event when someone checks a check box.

I think this can be done at client side with javascript.  I found this in the internet http://forums.asp.net/3/1238700/ShowThread.aspx

I have used the treeview from telerik which has this function using simple javascript.  See http://www.telerik.com/community/forums/thread/b311D-cekgk.aspx
