DevExpress UI controls automatically detect potentially dangerous data types, block their deserialization, and throw a security-related exception.

If you trust a certain custom type, use the RegisterTrustedClass method to enable deserialization:

C#

DevExpress.Utils.DeserializationSettings.RegisterTrustedClass(typeof(CustomClass));

VB.NET

DevExpress.Utils.DeserializationSettings.RegisterTrustedClass(GetType(CustomClass))

Use the RegisterTrustedAssembly method to enable deserialization for all data types in the specified assembly.
