Hi Ben,

Please have a look at the following code I tried to disable a menu item based on the RadListBox item checked state.

ASPX:

<telerik:RadMenu ID="RadMenu1" runat="server">
    <Items>
        <telerik:RadMenuItem runat="server" Text="Menu Item1">
            <Items>
                <telerik:RadMenuItem runat="server" Text="Item11">
                </telerik:RadMenuItem>
            </Items>
        </telerik:RadMenuItem>
        <telerik:RadMenuItem runat="server" Text="Menu Item1">
        </telerik:RadMenuItem>
    </Items>
</telerik:RadMenu>
<br />
<br />
<telerik:RadListBox ID="RadListBox1" runat="server" CheckBoxes="true" OnClientItemChecked="OnClientItemChecked"
    Width="200px">
    <Items>
        <telerik:RadListBoxItem runat="server" Text="Disable Item11" />
    </Items>
</telerik:RadListBox>

JavaScript:

<script type="text/javascript">
    function OnClientItemChecked(sender, args) {
        var menu = $find("<%= RadMenu1.ClientID %>");
        var menuItem = menu.findItemByText("Item11");
        if (sender.findItemByText("Disable Item11").get_checked() == true) {
            menuItem.disable();
        }
        else {
            menuItem.enable();
        }
    }
</script>

Thanks,
Princy.

Hello Ben,

Inside the JavaScript if condition you can set the menu item image using the set_imageUrl method. Please check the following code.

JavaScript:

if (sender.findItemByText("Disable Item11").get_checked() == true) {
            menuItem.disable();
            menuItem.set_imageUrl("../Images/YourImage.jpg");
        }

Thanks,
Princy
