You need to:
1) add a TableStyle to your datagrid.
2) for each column add a columnstyle to this tablestyle
3) for the bool column, make sure to add a DataGridBoolColumn and set its AllowNull property to false.

You can do this entirely from the designer, or entirely from code. For a code sample, check this FAQ:
How can I put a checkbox in a column of my DataGrid?
