How to expand all treeview nodes

[faisal]

Hi,

i am working on telerik tree view with the following code

var tree = $find("<%= RadTreeView1.ClientID %>");
                        var node = tree.findNodeByText('str');                     
                        node.select();
                    
 var nodes = tree.get_allNodes();
                        for (var i = 0; i < nodes.length; i++) {                      
                            if (nodes[i].get_nodes().get_count() != 0 && nodes[i].get_text()!="") {                             
                                nodes[i].expand();
                            }
                        }

i want to search a node by text. then i want to expand all the tree and also need a click on searched node. above code is not working properly. please guide me.
i shall be very thankful to you for that.

Regards,

Faisal

Hello,

Try the following.
JS:

<script type="text/javascript"
 function OnClientClick()
   {
      var treeview = $find('<%=RadTreeView1.ClientID%>');
      var node = treeview.findNodeByText("Test");
      node.set_selected(true);
      var nodes = treeview.get_allNodes();
      for (var i = 0; i < nodes.length; i++)
       {
          nodes[i].set_expanded(true);
       }
   }
</script>

Thanks,
Princy.

Hello faisal,

 Try the following approach:

function OnClientClick()
{
    var treeview = $find('<%=RadTreeView1.ClientID%>');
    var node = treeview.findNodeByText("Test");
    $telerik.$(">div .rtIn", node.get_element()).change()

    var nodes = treeview.get_allNodes();
    for (var i = 0; i < nodes.length; i++)
    {
        nodes[i].set_expanded(true);
    }
}

Kind regards,
