This binding

<tk:DataGridTextColumn Binding="{Binding Path=Id, Mode=OneWay}" 
Header="Sale No." Width="1*" />

Gives this error

A TwoWay or OneWayToSource binding cannot work on the read-only property 'Id' of type . . .

The "Id" property is indeed readonly, I thought though that Mode=OneWay would be sufficient.

I'm tired and I know I'm missing something obvious so I'll apologies now for asking a really dumb question.

Thanks
