Get DataContext from UserControl

Question

I have a user control whose datacontext is set with this:

<UserControl.Resources>
    <data:ArchivosViewModel x:Key="Data" />
</UserControl.Resources>

In this user control I want to load a grid view with a list of objects in 5 columns with several values (date, url, name... and a button to delete each row).

To add this button I want to use a command that I have in my UserControl ViewModel and a CommandParameter wich I'll have in my datagrid source datacontext.

I think the best way to do this would be to set the datacontext in that button to the staticresource but it is not working... Any idea of how to do this?

                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellTemplate>
        </sdk:DataGridTemplateColumn>
        <sdk:DataGridTemplateColumn Header="Eliminar">
            <sdk:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Button Width="Auto" Margin="5,0" Content="Eliminar Fichero" Command="{Binding EliminarArchivoCommand}" ></Button>
                </DataTemplate>
            </sdk:DataGridTemplateColumn.CellTemplate>
        </sdk:DataGridTemplateColumn>
    </sdk:DataGrid.Columns>
</sdk:DataGrid>

Thanks in advance.

try:

 Command="{Binding EliminarArchivoCommand,Source={StaticResource Data}}" 

and:

CommandArgument="{Binding}"
