Hi,

I'm having a problem with removing menu items from the client side.  Specifically, I run into an issue when I try to remove the last root menu item.

I have noticed that you have the same issue in your demo here:  http://demos.telerik.com/aspnet-ajax/menu/examples/programming/addremovedisableitemsclientside/defaultcs.aspx

To reproduce the problem, select "Books", click "Delete selected Item", then, select "Music" and click "Delete selected Item".  You will find that the Music menu item still exists in the menu, and when you move the cursor over the menu, it throws a javascript exception.  Is there a known work-around for this issue?

Thanks,

Brad

Hello Brad,

Thank you for reporting this issue. Removing the last root item indeed doesn't function properly. The workaround for now would be to use clear instead:

$find("RadMenu1").get_items().clear();

We'll take care fix the issue. As a token of our gratitude for your involvement, your Telerik points have been updated.

Kind regards,

FYI, this issue appears to still exist in the 2013.1.403.40  version of the Menu,

Also, when you call clear(), it appears that a 1 pixel sized "residue" of the menu border remains. This occurs in all browsers from what I have seen. I have attached screen captures. The first (menu_before_add_item.jpg) just depicts an area where I have an empty menu and dynamically add items via JavaScript. The second (menu_item_added.jpg), shows the menu after I add an item through JavaScript. The third (menu_after_clear), shows what remains after I clear all menu items. As you can see there appears to be a piece of the border remaining. It doesn't appear to matter which skin is used.

Hello,

Since I am not able to replicate the described issue I have attached a sample project that follows the provided instructions. Could you please clarify what exactly is different in your current project and elaborate a bit more on your scenario.

The case where the residue occurs is when you have an empty menu, add an item client-side, and them call clear to remove the item. Change your example to have an empty menu declared:

<telerik:RadMenu ID="RadMenu1" runat="server" Flow="Vertical" ClickToOpen="true">
    <Items>
    </Items>
</telerik:RadMenu>


then add an item client-side and then call clear to remove the item so the menu is empty once again, as per my screenshots.
