I have the following Combobox and TreeView on a page.
            <telerik:RadComboBox ID="ContextCombo" DataTextField="Name" DataValueField="Id" EmptyMessage="Select Context" 
                        AutoPostBack="True" runat="server" Height="200px" Skin="Office2007" Width="250px"  

                            <telerik:RadTreeView ID="QuestionsAndAnswersTree" runat="server"  
                            OnClientMouseOver="ClientMouseOver"  OnClientNodeDropping="onNodeDropping" 
                                <telerik:RadTreeViewContextMenu ID="ContextMenuLHRootCreateQuestion" runat="server"
                                            Text="Create Question" Value="CreateQuestion" /> 
                                     <collapseanimation type="None" /> 
                                        type="None" /> 

The client handlers are defined as
        <script type="text/javascript"
            function onNodeDropping(sender, args) { 
                // prompt for drag action / display dialog  
                var dest = args.get_destNode(); 
                //window.radopen("DragDropPromptDialog.aspx?EventArg=" + args, "DragPromptDialog"); 
            function ClientMouseOver(sender, args) { 

When I open this page in Firefox 3.6.3 the client events do not fire.
The error console of Firefox shows me this error - ClientMouseOver is not defined + a link pointing to the error in the generated file.Clicking on the link highlights the following code in the file
<div id="ctl00_MainContent_ContextCombo" class="RadComboBox RadComboBox_Office2007" style="width:250px;display:-moz-inline-stack;display:inline-block;zoom:1;*display:inline;"

Not sure if the error has something to do with the display attribute(-moz-inline=stack)
The page works fire on IE 8.
Please help!!!!

Hi Sid,

Thanks for contacting Telerik Support.

I've tested the code you provided. In the ticket info I see the version you are using is 2010.1 415. Is this true? With this version the code is working.

I set alert messages in both of the client-side functions to see whether the events are fired:

function onNodeDropping(sender, args) {  
                // prompt for drag action / display dialog   
                var dest = args.get_destNode();
                //window.radopen("DragDropPromptDialog.aspx?EventArg=" + args, "DragPromptDialog");  
            function ClientMouseOver(sender, args) {  
            alert("mouse is over");  

Anyway from your code I see you are using onclientnodedropping event but to be able to use Drag & Drop functionality you need to set EnableDragAndDrop attribute to true:

<telerik:radtreeview id="QuestionsAndAnswersTree" runat="server" onclientmouseover="ClientMouseOver" EnableDragAndDrop="true"

Find the attached test project in the .zip file.
