Hello,

Does anybody know if there is a way to disable checking Autorization in Items of Menu and PanelBar controls?. I've implemented a custome Authorize attribute based on database and a locatization routes (also based in database table) and the performance of the controls is very bad due to the stantard checking autorization.
 
Thanks in advance.

Hello Juan Pablo Perez,

You can set the URL property of the Menu items instead of their ControllerName and ActionName properties. Thus the menu/panelBar UI component will not authorize the set URL.

The second options is to modify WriteItem extension method placed in Telerik.Web.Mvc.UI.NavigationItemContainerExtensions namespace like so:
public static void WriteItem<TComponent, TItem>(this TItem item, TComponent component, IHtmlNode parentTag, INavigationComponentHtmlBuilder<TItem> builder)
    where TItem : NavigationItem<TItem>, IContentContainer, INavigationItemContainer<TItem>
    where TComponent : ViewComponentBase, INavigationItemComponent<TItem>
{
    if (component.ItemAction != null)
    {
        component.ItemAction(item);
    }
 
    if (item.Visible)
    {
        var hasAccessibleChildren = item.Items.Any()
                                    && item.Items.IsAccessible(component.Authorization, component.ViewContext)
                                    && item.Items.Any(i => i.Visible);
 
        IHtmlNode itemTag = builder.ItemTag(item).AppendTo(parentTag);
 
        builder.ItemInnerContentTag(item, hasAccessibleChildren).AppendTo(itemTag);
 
        if (item.Template.HasValue() ||
            (item is IAsyncContentContainer ? !string.IsNullOrEmpty(((IAsyncContentContainer)item).ContentUrl) : false))
        {
            builder.ItemContentTag(item).AppendTo(itemTag);
        }
        else if (hasAccessibleChildren)
        {
            IHtmlNode ul = builder.ChildrenTag(item).AppendTo(itemTag);
 
            item.Items.Each(child => child.WriteItem(component, ul, builder));
        }
    }
}

All the best,
