I am trying to get a CountainerBindingCollection and ContainBinding to work with my hierarchical data template in wpf but no matter what namespace I use it doesn't seem to recognize it.

This link is to one of your WPF pages showing the ContainerBinding being used and it seems to be in the same namespace as the RadMenu , I have Access to the Menu but not the ContainerBindings, is this page of information wrong?

http://www.telerik.com/help/wpf/radmenu-how-to-enable-disable-menu-items.html

At the bottom of this page there is a link 'to learn more about container bindings' which leads to a page that never even mentions the containerbinding

Hi Ben Boger,

ContainerBindnigs are only available for Silverlight. Their purpose is to workaround the missing Bindings in Style Setter. So you don't need them in WPF.
If you want to enable/disable RadMenuItems you could use ItemContainerStyle property and set the following setter:
<Style TargetType="telerik:RadMenuIte">
   <Setter Property="IsEnabled" Value="{Binding IsMenuItemEnabled}" />
</Style>

Where IsMenuItemEnabled is a property on your data item.

We will update this article. Thanks for pointing it out.

Kind regards,
Hristo

You have the same problem in your RadComboBox WPF documentation:

The documentation for WPF still has the same problem.

Also,Could you please guide me to the correct way to bind IsEnabled in a radcomboboxitem. Style Binding does not seem to work correctly.

Hello Darshan,

To bind the IsEnabled or any other property of RadComboBoxItem, use the approach shown in the Using Style Binding section of the article. I've attached a small example showing this approach. I hope it helps.
