MessageBox before delete - wpf datagrid

Question

I have a DataGrid in my WPF application where every row ends with a Delete button.

 <DataTemplate>
      <Button
       Command="Delete"
       CommandParameter="{Binding}" FontWeight="Bold" Foreground="{x:Null}" IsEnabled="True" BorderBrush="{x:Null}">
      <Button.Background>
      <ImageBrush ImageSource="Ikonok/bin.png"/>
      </Button.Background>
      <Button.Style>
        <Style TargetType="{x:Type Button}">
           <Setter Property="Template">
              <Setter.Value>
                 <ControlTemplate TargetType="{x:Type Button}">
                      <Border Background="{TemplateBinding Background}" BorderBrush="{x:Null}" BorderThickness="1">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                      </Border>
                 </ControlTemplate>
              </Setter.Value>
           </Setter>
        </Style>
     </Button.Style>
     </Button> </DataTemplate>

How can I write a code behind that drops a MessageBox before the delete action that asks if the user really want to delete that item?

When you fire event for the delete button place this code at the beginning of the event.

MessageBoxResult messageBoxResult = System.Windows.MessageBox.Show("Are you sure?", "Delete Confirmation", System.Windows.MessageBoxButton.YesNo);

if (messageBoxResult == MessageBoxResult.Yes)
{
     //...
}    
else
{
    //...
}
