WPF: How to bind the IsEnabled property of a button

With WPF how can I bind the IsEnabled property of a Button to the selected row's DataGridCheckBoxColumn value of my grid?

The button would look something like this

<Button Content="Update" IsEnabled="{Binding ElementName=grid, Path=SelectedItem.SomeValue}"/>
