Remarks
Use the AllowReadUnexposedColumnsFromClientApi property to restrict access to data source fields that are bound to columns and these columns are hidden in the ASPxGridView, ASPxCardView, and ASPxVerticalGrid controls.
ASPxGridView.SettingsDataSecurity.AllowReadUnexposedColumnsFromClientApi = DefaultBoolean.True;
ASPxCardView.SettingsDataSecurity.AllowReadUnexposedColumnsFromClientApi = DefaultBoolean.True;
ASPxVerticalGrid.SettingsDataSecurity.AllowReadUnexposedColumnsFromClientApi = DefaultBoolean.True;
If the AllowReadUnexposedColumnsFromClientApi property is set to Default, the client-side access to the data source’s unexposed fields depends upon the BackwardCompatibilitySettings.DataControlAllowReadUnexposedColumnsFromClientApiDefaultValue property setting.
Note
In version 18.1, we’ve changed this API behavior to improve data security of grid-like DevExpress web controls.
Breaking Change: The Specificity of accessing data field values from a client API of grid-like web controls topic illustrates details and describes how to revert to the previous behavior (degrading data security).
The AllowReadUnexposedColumnsFromClientApi property has priority over the BackwardCompatibilitySettings.DataControlAllowReadUnexposedColumnsFromClientApiDefaultValue property.
