ReadOnly controls whether a component can be used for input

Member of Edit Field (PRIM_MD.Edit)

Data Type - Boolean

Details

The ReadOnly property determines whether a control can be used for input.
 
ReadOnly differs from the Enabled property in that the control can still respond to user actions.
 
Readonly modifies the behavior of the visual control. It does not affect any associated data variable.

Example

This example shows the difference between fields that are enabled, disabled and readonly.
