Using the RadialMenu control, you can create both top-level menus and submenus. Let us discuss how to create the top-level menus and submenus in the following sections.

Create Top-Level Menus

  1. Place the following XAML between the <Grid> and </Grid> tags:
    XAML
    Copy Code 
    <c1:C1ContextMenuService.ContextMenu>
     <c1:C1RadialMenu> </c1:C1RadialMenu>
</c1:C1ContextMenuService.ContextMenu>

    The RadialMenu control is within a ContextMenuService. When you run your application, the menu will appear when you right-click or right-tap.

  2. Place the following XAML between the <c1:C1RadialMenu> and </c1:C1RadialMenu> tags. This will create three top-level menu items:
    XAML
    Copy Code 
    <c1:C1RadialMenuItem Header="RadialMenuItem1" />
<c1:C1RadialMenuItem Header="RadialMenuItem2" />
<c1:C1RadialMenuItem Header="RadialMenuItem3" />
  3. Run the program and observe the following:
    • Right tap or right-click the page. In this case, this is the element to which RadialMenu is attached. Observe that the Navigation Button appears.
    • Tap or click the Navigation Button to open the radial menu. Observe that the RadialMenu contains three C1RadialMenuItems.

    Your top-level menu should resemble the following image:

Create Submenus

  1. Create a RadialMenu:
    XAML
    Copy Code 
    <c1:C1ContextMenuService.ContextMenu>
     <c1:C1RadialMenu > 
    </c1:C1RadialMenu>
</c1:C1ContextMenuService.ContextMenu>
  2. Place the following XAML between the <c1: C1RadialMenu> and </c1:C1RadialMenu> tags:
    XAML
    Copy Code 
    <c1:C1RadialMenuItem Header="Tap Here" >
  <c1:C1RadialMenuItem Header="Item 1" />
  <c1:C1RadialMenuItem Header="Item 2" />
  <c1:C1RadialMenuItem Header="Item 3" />
</c1:C1RadialMenuItem>
  3. Run the program.
    • Right tap or right-click the page to display the Navigation Button. Tap or click the Navigation Button to display the main RadialMenu.
    • Tap or click the Tap Here item and observe that the submenu you created appears.

    This is the RadialMenu control after you tap or click the Tap Here item:
