Create Menu Button with RadContextMenu and ToggleButton

In some scenarios you need to have a button that displays additional options upon clicking. This tutorial will show you how to achieve such drop-down button behavior using only a ToggleButton and a RadContextMenu. The two things you have to do are the following:

• Attach a RadContextMenu to the ToggleButton

• Bind the IsChecked property of the ToggleButton to the IsOpen property of the RadContextMenu

Here is the final code snippet.

• XAML

<ToggleButton Content="Click me" 
              HorizontalAlignment="Left" 
              IsChecked="{Binding IsOpen, ElementName=radContextMenu, Mode=TwoWay}"> 
    <telerik:RadContextMenu.ContextMenu> 
        <telerik:RadContextMenu x:Name="radContextMenu" Placement="Bottom"> 
            <telerik:RadMenuItem Header="Item 1" /> 
            <telerik:RadMenuItem Header="Item 2" /> 
            <telerik:RadMenuItem Header="Item 3" /> 
        </telerik:RadContextMenu> 
    </telerik:RadContextMenu.ContextMenu> 
</ToggleButton> 

The things you have to make attention to here are: how the RadContextMenu is attached to the ToggleButton and the ElementBinding applied to the ToggleButton's IsChecked property.
