Telerik UI for Windows 8 XAML

Important

The RadRadialMenu can be used as a context menu for another FrameworkElement. This can be done by using attached properties defined in the RadRadialContextMenu class.

  • Menu (RadRadialMenu): Specifies the RadRadialMenu instance that will be attached to the target element.

  • Behavior (RadialMenuTriggerBehavior): Specifies the behavior class that will take care of the attachment/detachment of the menu to the target element and the positioning of the menu.

Default Behavior

You can use the default RadialMenuTriggerBehavior class and with the AttachTriggers property you have to specify the event that will trigger attachment of RadRadialMenu to the target element. Here are listed all available values:

  • None: The menu cannot be opened with an automatic trigger.

  • PointerPressed: The menu is opened when pointer press event occurs on the target element.

  • PointerOver: The menu is opened when pointer over event occurs on the target element.

  • Focused: The menu is opened when the target element gets focus.

  • PressedOrFocused: The menu is opened when the target element gets focus or press action.

Here is an example demonstrating how to define a behavior that will attach the menu when the target element is focused.

<TextBox Width="200">
    <telerikPrimitives:RadRadialContextMenu.Behavior>
        <telerikPrimitives:RadialMenuTriggerBehavior AttachTriggers="Focused" />
    </telerikPrimitives:RadRadialContextMenu.Behavior>
    <telerikPrimitives:RadRadialContextMenu.Menu>
        <telerikPrimitives:RadRadialMenu/>
    </telerikPrimitives:RadRadialContextMenu.Menu>
</TextBox>
Note

With the default RadialMenuTriggerBehavior you can not control the positioning and the detaching of the menu from the target element.

Here are examples that demonstrate how to extend the RadialMenuTriggerBehavior functionality:
