What Changed
Values in an invisible column are not saved to the server and reset to initial server values.
Reasons for Change
In previous versions, invisible column values can be changed using a client-side API. When a control gets cell values from the client, changed data is loaded into the database.
Impact on Existing Apps
This change affects your application if it contains a data control with invisible columns.
How to Change the Default Behavior
- We introduced the BackwardCompatibilitySettings.DataControlPreventLoadClientValuesForInvisibleColumns property with the default value set to true. Set this property to false to return to the previous behavior.
- Use the DataControl.SettingsDataSecurity.PreventLoadClientValuesForInvisibleColumns property to change the described behavior for a particular control.
