    Hi!!

    I was trying to expand/collapse all nodes client side and I saw this page teaching with a very simple code:

    http://www.telerik.com/help/aspnet-ajax/tree_clientexpandingcollapsing.html

    I was very happy but when I tested it, didn't work. I guess it's because I'm using Q3 and not prometheus. Now, I have three questions:

    1. Is there a easy way to do the same with Q3?
    2. How can I know, when exploring telerik web page, that I'm at a prometheus help article and not at Q3, since I haven't see any description about it in the page?
    3. Where can I find help pages just for Q3?

    We still doesn't have the prometheus version here (we depends from the directors to buy), but we have the beta version files here, so we could find that the method get_allNodes() was from Prometheus, analysing the script files.
    Thanks in advance and god bless!

    Hello Eric,

    I guess you are still using the old "Classic" version of RadTreeView for ASP.NET, but you are looking through the documentation of the new AJAX version of the control.

    Here's a sample code snippet that shows the needed approach for RadTreeView for ASP.NET.

    <form id="form1" runat="server">  
        <asp:ScriptManager ID="ScriptManager1" runat="server" /> 
     
        <script type="text/javascript">  
        function treeExpandAllNodes()  
        {  
            var tree = <%= RadTreeView1.ClientID %>;  
            var i;  
            for(i=0; i<tree.AllNodes.length; i++)  
            {  
                tree.AllNodes[i].Expand();  
            }  
        }  
     
        function treeCollapseAllNodes()  
        {  
            var tree = <%= RadTreeView1.ClientID %>;  
            var i;  
            for(i=0; i<tree.AllNodes.length; i++)  
            {  
                tree.AllNodes[i].Collapse();  
            }  
        }  
        </script> 
     
        <rad:RadTreeView ID="RadTreeView1" runat="server">  
            <Nodes> 
                <rad:RadTreeNode runat="server" Text="New Item">  
                    <Nodes> 
                        <rad:RadTreeNode runat="server" Text="New Item">  
                        </rad:RadTreeNode> 
                        <rad:RadTreeNode runat="server" Text="New Item">  
                        </rad:RadTreeNode> 
                    </Nodes> 
                </rad:RadTreeNode> 
                <rad:RadTreeNode runat="server" Text="New Item">  
                    <Nodes> 
                        <rad:RadTreeNode runat="server" Text="New Item">  
                        </rad:RadTreeNode> 
                        <rad:RadTreeNode runat="server" Text="New Item">  
                            <Nodes> 
                                <rad:RadTreeNode runat="server" Text="New Item">  
                                </rad:RadTreeNode> 
                                <rad:RadTreeNode runat="server" Text="New Item">  
                                    <Nodes> 
                                        <rad:RadTreeNode runat="server" Text="New Item">  
                                        </rad:RadTreeNode> 
                                        <rad:RadTreeNode runat="server" Text="New Item">  
                                        </rad:RadTreeNode> 
                                        <rad:RadTreeNode runat="server" Text="New Item">  
                                        </rad:RadTreeNode> 
                                    </Nodes> 
                                </rad:RadTreeNode> 
                                <rad:RadTreeNode runat="server" Text="New Item">  
                                </rad:RadTreeNode> 
                                <rad:RadTreeNode runat="server" Text="New Item">  
                                </rad:RadTreeNode> 
                            </Nodes> 
                        </rad:RadTreeNode> 
                        <rad:RadTreeNode runat="server" Text="New Item">  
                        </rad:RadTreeNode> 
                        <rad:RadTreeNode runat="server" Text="New Item">  
                        </rad:RadTreeNode> 
                    </Nodes> 
                </rad:RadTreeNode> 
            </Nodes> 
        </rad:RadTreeView> 
        <a href="javascript: treeExpandAllNodes();" class="RadTreeView_Hay">Expand All Nodes</a> 
        <a href="javascript: treeCollapseAllNodes();" class="RadTreeView_Hay">Collapse All Nodes</a> 
    </form> 

    In addition, here's the documentation for RadTreeView for ASP.NET.
