I have used a RadTreeView control in an aspx page, where the Root element has been associated an "Add " context menu.

While the ContextMenuItemClick event is fired on the server side when viewed from Opera 11, Firefox 11, Chrome 17, Internet Explorer 8, it does not fire when viewed from Internet Explorer 9 - it only adds a # tag at the end of the URL and no PostBack is executed.

I have tried to set the PostBack property of the Context menu item to true, to false - to no avail.

Please let me know if there is something that I am missing.

Thank you.

PS. Below is the mark-up used in my page:

<telerik:RadTreeView ID="CollectiveNameTree" runat="server"
    <WebServiceSettings Path="~/WebServices/Substances.asmx" Method="GetTreeViewCategories" />
        <telerik:RadTreeNode Text="<%$ Resources:Buttons,ClassificationsRootNodeTitle %>" PostBack="true"
            Expanded="false" ExpandMode="WebService" Value="1" ContextMenuID="RootContextMenu" />
        <telerik:RadTreeViewContextMenu ID="RootContextMenu" runat="server">
                <telerik:RadMenuItem Value="AddClassification"
                    Text="<%$ Resources:Buttons,AddClassification %>" />

Hi Zoltan,

I have inspected the issue by adding the code that you provided to our online demo but could not observe the described unusual behavior. Here you can see a video of my test in IE(. Please review it and let me know if I am not testing properly or if I have to add some additional code in order to observe the same behavior.

All the best,

Hi Plamen,

It seems my issue was occuring due to an older version of the Telerik TreeView. Thank you for testing the issue.

With kind regards,
