You can access this nested property as listed below:
| Object Type | Path to IsReadOnly |
|---|---|
| LayoutControl |
.OptionsView .IsReadOnly
|
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.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the IsReadOnly property.
