The DataGridViewCheckBoxColumn class is a specialized type of the class used to logically host cells that indicate binary state. A DataGridViewCheckBoxColumn has an associated in every that intersects it. Each cell supplies a user interface (UI) that is similar to a control. The default sort mode for this column type is.

Also the control gives you ability to display hierarchical data.

DataGridView doesn't directly support row expanding/collapsing, see. Although following trick doesn't seem robust to me, you can use filtering by a hidden column to emulate row collapsing/expanding. To make a +/- sign you can engage with custom check images. Once user checks/unchecks a cell in this column, you can traverse all children of the affected row and update the hidden column value to show or hide them. By comparison with master/detail approach this trick allows to show deep hierarchies.
