GrapeCity.ActiveReports.Data Namespace

In This Topic

The GrapeCity.ActiveReports.Data namespace contains the classes used for section report data binding in section reports.

Classes

	Class	Description
	CsvDataSource	Represents a section report data source based on an CSV document.
	DbDataSource	DB data source - allows to connect through custom database providers.
	Field	The Field class represents any data field available for data binding in section reports.
	FieldCollection	The FieldCollection class manages the data binding fields used in the section report.
	JsonDataSource	Represents a section report data source based on a JSON document.
	ListDataSource	Represents a section report data source based on the IDataRecord and IDataReader members of the .NET Framework.
	OdbcDataSource	ODBC data source - allows to connect through ODBC driver.
	OleDBDataSource	Represents a section report data source based on the OleDb ADO.NET data provider.
	SqlDBDataSource	Represents a section report data source based on the SqlDB ADO.NET data provider.
	XMLDataSource	Represents a section report data source based on an XML document and an XPath pattern to select the XML nodes used as records in the data source.

Interfaces

	Interface	Description
	IListDataSource	Wrapper over System.Collections.IList interface to use it as data source: GrapeCity.ActiveReports.SectionReport.DataSource. This should be used only if performance of current implementation is not enough. This snippet shows how to implement the interface with https://www.nuget.org/packages/FastMember.Signed/1.5.0 Note: Product here is custom business object. class Product { public int ProductID { get; set; } public string ProductName { get; set; } } class FastListDataSource : IListDataSource { private readonly System.Collections.Generic.IList < Product > _list; private readonly System.Data.IDataReader _reader; public FastListDataSource(System.Collections.Generic.IList < Product > list) { _list = list; _reader = FastMember.ObjectReader.Create(_list); } public object GetValue(string fieldName, int ordinal) { var index = fieldName.IndexOf('.'); if (index == -1) return _reader.GetValue(ordinal); var fields = fieldName.Split('.'); var target = _reader.GetValue(ordinal); for (int i = 1; i != fields.Length; i++) target = FastMember.ObjectAccessor.Create(target)[fields[i]]; return target; } public int GetOrdinal(string fieldName) { var index = fieldName.IndexOf('.'); if (index == -1) return _reader.GetOrdinal(fieldName); return _reader.GetOrdinal(fieldName.Substring(0, index)); } public System.Collections.IList List => (System.Collections.IList)_list; public System.Data.IDataReader DataReader => _reader; }

Enumerations

	Enumeration	Description
	FieldTypeEnum	Provides a set of values for use with the FieldType property of the Field class.
