    I use the following code to enable multiple selection in the radtreeview. The code only works in IE and not in Chrome or FireFox. 
    Could someone help me with this issue?


    <telerik:RadCodeBlock ID="cb1" runat="server">

            <script language="javascript" type="text/javascript">
            var RadTreeIsMultiSelecting = false;
            function CommitTree(e)
                if (!e.ctlrKey | !e.shiftKey) 
                    if (RadTreeIsMultiSelecting)
                        var aMan = $find("<%= ajMan.ClientID %>");

            function RadTreeClicked(sender, args)
                RadTreeIsMultiSelecting = args._domEvent.ctrlKey | args._domEvent.shiftKey;
                var tree = $find("<%= RadTree.ClientID %>");

    Hello Amir,

    RadTreeView already supports multi-selection - both using the shift and ctrl key.
    You only need to set the MultipleSelect property of RadTreeView's to true.
