如何从Datatable填充WPF Datagrid？

I am new here so forgive me if this is the wrong section for my question. My problem is that I can't populate a datgrid with the contents of a dataset. Having searched for the last few days to try and resolve this, I have given up and thought I would try here.

A popular solution in my searches was to add '.DataSource' but when I type the '.' after dgBOM the Datasource option is not there.I am new here so forgive me if this is the wron
