Hi,

Given a node of a tree view, how can I collapse all the nodes of the whole tree view. Or is there a TreeView.Collapse All function?

Like this

treeview.ExpandLevel = 0;
treeview.FindAll(delegate(FlyTreeNode node)
                           {
                               node.Expanded = null;
                               return false; // or true - doesn't matter
                           });



FindAll method recursively loops through all nodes

Sorry, not quite get it. Here is my coding:

var treeview;

//Script for flyTreeView_onInitialized() must be in the very top of the source
function flyTreeView_onInitialized(treeviewObject) {
    treeview = treeviewObject;
}

function CollapseAllNode(item, argument) {

...

}

Please file in the menu item Javascript CollapseAllNode() for me. Thanks.

Oh, I see, you need the javascript function not server-side.

Here's the same for client side:

treeview.findAll(function(node) {node.collapse();});

treeview is your client-side treeview instance.
