Property Value

True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.

Remarks

If the IsReadOnly property is set to True or False, the read-only state is automatically enabled and disabled, respectively, for all BaseEdit and System.Windows.Forms.TextBoxBase class descendants within the LayoutControl. In these modes, you cannot change the read-only state for individual controls using their ReadOnly properties.

If the IsReadOnly property is set to Default, the read-only state of the embedded controls is not affected by the LayoutControl. In this mode, you can make individual controls read-only using their ReadOnly properties.
