Füllen Sie Ihre Datenbankserverinformationen wie folgt aus:

CrystalDecisions.Shared.TableLogOnInfo crLogonInfo; 
crLogonInfo = this.crystalReport.Database.Tables[0].LogOnInfo; 
crLogonInfo.ConnectionInfo.ServerName = SystemConfiguration.DBInstance.SQLServerName; 
crLogonInfo.ConnectionInfo.UserID = SystemConfiguration.DBInstance.SQLUserID; 
crLogonInfo.ConnectionInfo.Password = SystemConfiguration.DBInstance.SQLPassword; 
crLogonInfo.ConnectionInfo.DatabaseName = SystemConfiguration.DBInstance.SQLDatabaseName; 
this.crystalReport.Database.Tables[0].ApplyLogOnInfo(crLogonInfo);
