class

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.
