                System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(this.MapPath("Rel_proposta_teste.trdx"), settings);


                Telerik.Reporting.XmlSerialization.ReportXmlSerializer xmlSerializer = new Telerik.Reporting.XmlSerialization.ReportXmlSerializer();
                Telerik.Reporting.Report report = (Telerik.Reporting.Report)xmlSerializer.Deserialize(xmlReader);
                Rel.SetReportConnectionString(report, Convert.ToString(((Databases)Application["Databases"]).DataBaseList["Bdescala"].StringConnection)); <<<here problem>>>
                report.ReportParameters["Param_idproposta"].Value = Param_idproposta_inicio;


                // Atenção = altere o parâmetro “pld_entidade” para o parâmetro que vc criou no Reporting Telerik. 

                this.ReportViewer1.ReportSource = new Telerik.Reporting.InstanceReportSource

                   ReportDocument = report,
               };

            }
            catch (Exception ex)

            }
}

{

public static void SetReportConnectionString(Telerik.Reporting.Report reportDocument, String connectionString)
        {
            Telerik.Reporting.SqlDataSource sds = (Telerik.Reporting.SqlDataSource)reportDocument.DataSource;
            if (sds != null)
                sds.ConnectionString = connectionString;
            SetReportConnectionString(reportDocument.Items, connectionString);
        }
        public static void SetReportConnectionString(Telerik.Reporting.ReportItemBase.ItemCollection items, String connectionString)
        {
            foreach (Telerik.Reporting.ReportItemBase ib in items)
            {
                if (ib.Items != null)
                {
                    SetReportConnectionString(ib.Items, connectionString);
                }
                Type type = ib.GetType();
                System.Reflection.PropertyInfo dataSourceProperty = type.GetProperty("DataSource");
                if (dataSourceProperty == null)
                    continue;
                var dataSource = dataSourceProperty.GetValue(ib, null) as Telerik.Reporting.SqlDataSource;
                dataSource.ConnectionString = connectionString;
            }
        }

Hi,

Give a shot to this - Changing the connection string dynamically according to runtime data.
And test to pass the connection string directly, without checking the database list, because it might be the problem.
