DevExpress controls use a safety mechanism for all deserialization operations to improve app security. An exception is thrown if a control attempts to load an unsafe type.
Deserialize Trusted Types
You should review all unsafe type exceptions. If you trust a certain exception type, use the following code to enable deserialization:

Trust a Section of Your Code
If you trust a data source that raised a given security exception, you can turn off safe deserialization for certain sections of code:
