Reporting for WinForms - Override the Default Isolation Level

This example overrides the default isolation level (READ COMMITTED) for a specific query. It allows users to retrieve information without being locked by another process that modifies the same data.

Example Overview

1. Implement the IDBCommandInterceptor interface (NolockInterceptor.cs in this example). Call the IDBCommandInterceptor.CommandCreated(String, IDbCommand) method and specify CommandText to execute.

2. Call the XRDesignMdiController.AddService method to register the interceptor.
