Enable and Disable Menu Items

This topic will show you how to enable and disable menu items. There are several major cases that will serve as examples:

  • Disable all menu items

  • Disable a static menu item

  • Disable a dynamic menu item

Disable all Menu Items

Disabling all menu items can be easily done by just setting the IsEnabled property of the RadMenu parent control to False.

<telerik:RadMenu VerticalAlignment="Top" IsEnabled="False"> 
</telerik:RadMenu> 
This will disable the top-level menu items and they won't be expandable.

Disable a Static Menu Item

To disable a static menu item you just have to set its IsEnabled property to False.

<telerik:RadMenuItem Header="Save as ..." IsEnabled="False" /> 

Note that disabling an item will prevent it from expanding its child items (if any).

Disable a Dynamic Menu Item

Before you continue reading this topic, you might find useful to take a look at the Binding to Dynamic Data topic.

In order to disable a dynamic menu item you have to bind its IsEnabled property to the appropriate boolean property of your data item. To do this you can set the ItemContainerStyle property of RadMenu.

<telerik:RadMenu> 
    <telerik:RadMenu.ItemContainerStyle> 
        <!-- if you use NoXaml dlls, set the following property on the Style object: BasedOn="{StaticResource RadMenuItemStyle}" --> 
        <Style TargetType="telerik:RadMenuItem"> 
            <Setter Property="IsEnabled" Value="{Binding CanClickItem}" /> 
        </Style> 
    </telerik:RadMenu.ItemContainerStyle> 
</telerik:RadMenu>
