Object Type	Path to IsReadOnly
LayoutControl	.OptionsView .IsReadOnly

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.
