DataGridBoolColumn

Synopsis

This DataGridColumnStyle class supports true/false values, representing them as a checkbox. If you set the AllowNull property, you can extend this to true/false/null support, with a tristate checkbox.

In addition to the base behavior, you can set the TrueValue, FalseValue, and NullValue properties (the object values that represent true, false, and null), in the particular data type of the bound column.
