What Changed
The value of a read-only editor is not saved to the server and is reset to the initial server value.
Reasons for Change
In previous versions, a read-only editor value could be changed by using client-side APIs. When a control obtains a cell value from the client, modified data is saved to the server.
Impact on Existing Apps
This change affects your application if it includes a data editor in read-only mode.
How to Change the Default Behavior
We introduced the BackwardCompatibilitySettings.DataEditorsPreventLoadClientValuesForReadOnlyControls property with its default value set to true. Set this property to false to return to the previous behavior.
