Determines whether the field can be modified.

Pascal
property ReadOnly: Boolean;
C++
__property Boolean ReadOnly;
Description

Set ReadOnly to true to prevent a field from being modified. In a data grid, tabbing from field to field skips over ReadOnly fields. 

To learn whether a field can be modified, use the CanModify property instead. CanModify reflects not only the value of the ReadOnly property, but also any restrictions imposed by the underlying dataset.
