searching nodes in RadTreeView

[Bassem]

i'm doing a project where i can search a node withing my treeView my code so far is this:

function expandAllAncestors(node) {
            if (node.get_expanded() !== true)
                node.expand();

            if (node.get_level() != 0) {
                expandAllAncestors(node.get_parent());
            }
        }

        function SearchClick() {

            var search = $get("<%= ApplicationSearchResult.ClientID %>").value;
            var treeView = $find("<%= MainTree.ClientID %>");
            var nodes = treeView.get_allNodes();
            var NextNode = document.getElementById("<%=NextNode.ClientID %>");
            NextNode.style.display = "block";
            for (var i = 0; i < nodes.length; i++) {
                var node = nodes[i];
                if (node.get_text() == search) {
                    node.set_selected(true);
                    expandAllAncestors(node);
                    return;
                }
            }

         }

I need a simple code so when i search the tree for the second time all the opened nodes should be collapsed and only the searched one is expended

Hi Bassem,

Please modify your code as follows to achieve your scenario.

Javascript:

<script type="text/javascript">
  function expandAllAncestors(node)
  {
   if (node.get_expanded() !== true)
   node.expand();
   if (node.get_level() != 0)
   {
    expandAllAncestors(node.get_parent());
   }
  }
  function SearchClick()
  {
   var search = $get("<%= ApplicationSearchResult.ClientID %>").value;
   var treeView = $find("<%= MainTree.ClientID %>");
   var nodes = treeView.get_allNodes();
   for (var i = 0; i < nodes.length; i++)
   {
    nodes[i].collapse();
   }
   for (var i = 0; i < nodes.length; i++)
   {
    var node = nodes[i];
    if (node.get_text() == search)
    {
     node.set_selected(true);
     expandAllAncestors(node);
     return;
    }
   }
  }
</script>

Hope this helps.

Thanks,
Princy.
