ItemsPresenter bind CommandParameter to item

I have an ItemsPresenter with a context menu.  In the context menu there is one menuitem and I want to bind the CommandParameter of the MenuItem to the Item inside of the ItemsPresenter. But I'm having trouble getting to the Item.  How Do I bind the CommandParameter to the Item?  The item is a ViewModel Object I created.

                                                                <ItemsPresenter Margin="24,0,0,0" >
                                                                    <ItemsPresenter.ContextMenu>
                                                                        <ContextMenu>
                                                                           <MenuItem Header="Remove file from OCR list" Command="{x:Static commands:OCRCommands.RemoveFile}"   CommandParameter="{Binding}">
                                                                                <MenuItem.Icon>
                                                                                    <Image Source="/ThemeManager;component/Images/Delete - Copy.png" Width="15"  Margin="5"/>
                                                                                </MenuItem.Icon>
                                                                            </MenuItem>
                                                                        </ContextMenu>
                                                                    </ItemsPresenter.ContextMenu>
                                                                </ItemsPresenter>
<GroupStyle x:Key="groupItemStyle">
                                <GroupStyle.ContainerStyle>

Hello,

I've added screenshot of when my Execute Command Handler is called.  When I bind using CommandParameter="{Binding}"  I get an object of the MS.Internal.DataCollectionViewGroupInternal.
In Debug mode I looked inside this object and I see it as a collection and the Item I really wanted to bind to is present in the collection.  My question is how to I bind directly to my object via XAML.

I've attached a screenshot showing what I got and What I'm trying to get.

Hi,

I found the solution after looking at this article:

http://blogs.msdn.com/b/vinsibal/archive/2009/01/21/exploring-mvvm-grouping-with-the-datagrid.aspx


The key was to bind to Items[0].

<MenuItem Header="Remove file from OCR list"
                                                                                      Command="{x:Static commands:OCRCommands.RemoveFile}"
                                                                                      CommandParameter="{Binding Path=Items[0]}">



<ItemsPresenter Margin="24,0,0,0" >
                                                                    <ItemsPresenter.ContextMenu>
                                                                        <ContextMenu>
                                                                            <MenuItem Header="Remove file from OCR list" 
                                                                                      Command="{x:Static commands:OCRCommands.RemoveFile}"
                                                                                      CommandParameter="{Binding Path=Items[0]}">
                                                                                <MenuItem.Icon>
                                                                                    <Image Source="/Dms.ThemeManager;component/Images/Delete - Copy.png" Width="15"  Margin="5"/>
                                                                                </MenuItem.Icon>
                                                                            </MenuItem>
                                                                        </ContextMenu>
                                                                    </ItemsPresenter.ContextMenu>
                                                                </ItemsPresenter>
