hi,<BR><BR>I have used microsoft treeview webcontrol with a checkbox in each node (using c#.net) to draw a tree.<BR>The tree is directly formed from the xml. Tree is not created dynamically.<BR><BR>But when i check the parent, I want all its children to be checked automatically and on unchecking the parent, all its children must be unchecked. Can anyone help me out with the javascript to do this?<BR><BR>Thanks<BR>vince
