Remarks

Use the PreventLoadClientValuesForReadOnlyColumns property to specify whether to load read-only column values from the client to the server side.

C#

ASPxTreeList.SettingsDataSecurity.PreventLoadClientValuesForReadOnlyColumns = DefaultBoolean.True;

If the PreventLoadClientValuesForReadOnlyColumns property is set to Default, access to read-only values from the server side depends upon the DataControlPreventLoadClientValuesForReadOnlyColumns property setting.

Note

• In version 17.2, we’ve changed this API behavior to improve data security of the DevExpress Tree List web control.

  Breaking Change: The A read-only column’s editors reset client values to initial server values topic illustrates details and describes how to revert to the previous behavior (degrading data security).

• The PreventLoadClientValuesForReadOnlyColumns property has priority over the DataControlPreventLoadClientValuesForReadOnlyColumns property.
