ListViewItem Context Menu Get Data from ListViewItem - wpf

Question

I'm trying to create a context menu, so that when you right click the ListViewItem, the user is presented with a list of options. The problem is; I can't get the refrenced item linked to the ListViewItem in the Click event.
I think it may be because I'm putting the ContextMenu in the wrong place in my XAML. I have been searching and playing around for ages, but think it could have something to do with the DataTemplate I'm using where the examples weren't in templates.
<ListView Margin="0" Name="FileImagesListView" VerticalAlignment="Top" Grid.Row="0">
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<EventSetter Event="Mouse.MouseEnter" Handler="MouseEnterPicFileListItem" />
<EventSetter Event="Mouse.MouseLeave" Handler="MouseLeavePicFileListItem"/>
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<Border BorderBrush="{Binding Path=BorderBrushColourID, Converter={StaticResource BorderColourConverter}}" BorderThickness="3" CornerRadius="2">
<StackPanel FlowDirection="LeftToRight" Orientation="Vertical" Margin="3">
<Grid>
<TextBlock TextAlignment="Center" Text="{Binding Path=TimeAgo}" Margin="0,7" ></TextBlock>
<Label Style="{StaticResource CircularLabel}" HorizontalAlignment="Right" Height="35" Margin="0,-8,0,0" Content="{Binding Path=MatchedCount}" Visibility="{Binding Path=MatchedCount, Converter={StaticResource VisibleIfGreaterThanOne}}" ></Label>
</Grid>
<Image Name="FilePic" Height="Auto" Width="160" Source="{Binding Path=BitmapPicture}"></Image>
</StackPanel>
</Border>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Margin="3" Orientation="Horizontal"></StackPanel>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
</ListView>

Usually you can get the data item by just calling myListViewItem.DataContext and casting it into whatever it should be.
private void ListViewItem_Click(object sender, EventArgs e)
{
ListViewItem item = sender as ListViewItem;
if (item == null) return;
MyDataItem = item.DataContext as MyDataItem;
// Do whatever here
}
As a side note, WPF ContextMenus do not share the same VisualTree as your application, so trying to bind them to your main UI works differently. Its hard to tell if that is related to your problem because I see no ContextMenu or Click event in your question.
Edit
If your ContextMenu is on a ListBoxItem, then you need to refer to your ContextMenu's PlacementTarget to get the ListBoxItem that the ContextMenu is attached to
