I have item container style for list view like below : 

```
<ListView.ItemContainerStyle>
    <Style>
        <Setter Property="Padding" Value="0"></Setter>
        <Setter Property="Margin" Value="0,0,0,-1"></Setter>
        <Style.Triggers>
            <DataTrigger Binding="{Binding Path=EventType}" Value="2">
                <Setter Property="Background" Value="Green"/>
                <Setter Property="Foreground" Value="White"></Setter>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</ListView.ItemContainerStyle>

```

Now I need to add new setter for context menu programatically based on item data. How can I do it ?

Please guide me.....

Thanks
