Same method for multiple controls when using Caliburn.Micro

Question

In WPF MVVM application, I need same functionality for multiple controls - for example certain button does same thing as certain menu item. It is piece of cake with MVVM Light's RelayCommand, but I am now using Caliburn.Micro, where almost everything is based on conventions. So two controls can not have same x:Name="AddItem", which is used by CM to determine method for executing in ViewModel. Is there any simple way to solve this?

Yes, it's simple, but verbose. You need to use the "long format". Let's say you have one method IncrementCount on your ViewModel:

// Handling event
public void IncrementCount()
{
    Count++;
}

And your View has:

<Button Name="ButtonOne">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <cal:ActionMessage MethodName="IncrementCount" />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Button>

<Button Name="ButtonTwo">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <cal:ActionMessage MethodName="IncrementCount" />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Button>

Both buttons will call your IncrementCount method.

EDIT

Add these namespaces

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:cal="http://www.caliburnproject.org"
