VB.NET

<DefaultValue(DefaultBoolean.Default)>
Public Overridable Property AllowReadUnexposedColumnsFromClientApi As DefaultBoolean

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.

C#

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.
