    lvUsers.ItemsSource = loademp().DefaultView; makes no sense at all. Did you perhaps intend to write lvUsers.ItemsSource = items;? And is DisplayedImage a property of DataTable?

You could use a RelativeSource to bind to a property of the view model from within the CellTemplate:



<GridViewColumn Width="50" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<Border Width="30" Height="30" Background="Yellow" >
<Image Width="10" Height="10" Stretch="Fill"
Source="{Binding Path=DataContext.DisplayedImage, RelativeSource={RelativeSource AncestorType=ListView}}"
HorizontalAlignment="Center" Margin="0,0,0,0" />
</Border>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>


The default DataContext of the Image is an item in the ItemsSource and this one has no DisplayedImage property apparently.
