About

The PreExecuteReportSet method is used to modify the report before it is sent to the Report Viewer or Report Preview for viewing. Overriding this method can add granular control of fields, filters, and other properties of the report before the person designing/viewing the report will see it. This method should be overridden inside your CustomAdHocConfig class within your global.asax page.

Global.asax (C♯)

public class CustomAdHocConfig : DatabaseAdHocConfig
{
        public static void InitializeReporting() 
        {
                //Check to see if we've already initialized.
                if (HttpContext.Current.Session == null || HttpContext.Current.Session["ReportingInitialized"] != null)
                    return;
                AdHocSettings.LicenseKey = "INSERT_YOUR_LICENSE_KEY_HERE";
                AdHocSettings.SqlServerConnectionString = "INSERT_YOUR_CONNECTION_STRING_HERE";
                AdHocSettings.AdHocConfig = new CustomAdHocConfig();
                //Global and per-user initialization settings will be configured here
                HttpContext.Current.Session["ReportingInitialized"] = true;
        }

        public override void PreExecuteReportSet(ReportSet reportSet)
        { 
                //put your own custom code inside this method
        }
}
