C1.WPF.Report.DataSource

DataSource Class

Represnts a data source in a FlexReport.

Inheritance

object

ReportObject

StrongNamedReportObject

DataSource

Namespace: C1.WPF.Report

Assembly: C1.WPF.Report.dll

Syntax

[TypeConverter(typeof(ExpandableObjectConverter))]
public class DataSource : StrongNamedReportObject

Remarks

Most reports specify their data sources by setting the ConnectionString and RecordSource properties. The DataSource object uses these values to connect to a database and retrieve the report data.

Alternatively, you can assign data objects directly to the Recordset property. This approach is more efficient in scenarios where the data has already been loaded by the application for other purposes, and can be used in the report directly instead of loading a copy.

Constructors

Name	Description
DataSource()	Initializes a new instance of the DataSource class.

Fields

Name	Description
c_DefIsolationLevel	Defines default IsolationLevel for transaction used to get report data.

Properties

Name	Description
CalculatedFields	Gets the CalculatedFieldCollection collection defining list of calculated fields for the data source.
CommandTimeOut	Gets or sets the number of seconds to wait before the data connection times out (set to -1 to use the default value, usually 30s).
ConnectionString	Gets or sets the connection string used to open a database.
DataProvider	Gets or sets the type of the data source. The data source type determines the syntaxes of connection string and query (record source). The default is Auto but it is recommended that you set this value to the specific type of the data source you are using, as automatic determining of the data source type may be rather slow.
EncloseParameterValues	Gets or sets a value indicating whether values of parameters in resulting SQL query should be enclosed with delimiters, "#" for dates, "'" for strings, "()" for multivalue parameters. If this parameter is false when all parameters in RecordSource already should be enclosed. For example, EncloseParameterValues == true: RecordSource = "select * from customers where name = CustomerName"; actual SQL query will be: select * from customers where name = 'Some customer' EncloseParameterValues == false: RecordSource = "select * from customers where name = 'CustomerName'"; actual SQL query will be: select * from customers where name = 'Some customer'
FactoryName	The DbFactoryName string used to open a database.
Filter	Gets or sets the expression used to filter which data rows are included in the report.
FilterSyntax	Gets or sets the type of syntax used in the Filter.
IsolationLevel	Gets or sets the isolation level for DbTransaction used to retrieve the report data. The default is IsolationLevel.ReadCommitted.
MaxRecords	Gets or sets the maximum number of data rows to be included in the report (zero includes all rows).
ParameterPassingMode	Gets or sets a value indicating how parameter values are passed to the data engine.
ParentReport	Gets the report that contains this DataSource.
RecordSource	Gets or sets a string that specifies which table, stored procedure, or Sql command to use for retrieving the report data.
RecordSourceType	Gets or sets the type of the RecordSource (stored procedure, table, sql query etc.).
Recordset	Sets or gets the data source object that provides data to the report.
SortDefinitions	Gets the SortDefinitionCollection collection defining sort of the data source.
