Use this property to bind the component to values that can be null.
For example, the InputCheckBox component has a boolean InputCheckBox.Checked property of type boolean that can be bound to boolean fields, the InputNumericBox component has a Value property of type decimal that can be bound to numeric fields, and the InputDatePicker has a Value property of type System.DateTime that can be bound to date fields.
These are all value types and thus cannot be set to null or System.DBNull.Value. All these properties map internally to the BoundValue property, which is of type System.Object and can be set to null.
