C# Datagridview does not sort Checkbox column

Question

When I bind a Linq-to-sql query to a datagridview (using a BindingSource in between), the columns are sortable by default. However, this does not seem to be the case for boolean

Answer 1

In VS2012 in the designer you can also set the SortMode.

Right-click on the DataGridView and go to "Edit Columns".

There's a drop-down for SortMode with a choice of NotSortable, Automatic, and Programmatic.

It appears that the default for most columns is Automatic, but for checkboxes (boolean) columns the default is NotSortable.
