Syntax

public class Dictionary : Base, IFRSerializable, IParent

Remarks

You can access the report dictionary via Report.Dictionary property.

Constructors

Dictionary()

Initializes a new instance of the Dictionary class with default settings.

Declaration

public Dictionary()

Properties

Connections

Gets a collection of connection objects available in a report.

Declaration

public ConnectionCollection Connections { get; }

Gets a collection of cubesources available in a report.

Declaration

public CubeSourceCollection CubeSources { get; }

Methods

AddChild(Base)

Adds a child object to this object's childs.

Declaration

public void AddChild(Base child)

Parameters

Type	Name	Description
Base	child	Object to add.

Assign(Base)

Copies the contents of another, similar object.

Declaration

public override void Assign(Base source)

Parameters

Type	Name	Description
Base	source	Source object to copy the contents from.

Overrides

Base.Assign(Base)

Remarks

Call Assign to copy the properties from another object of the same type. The standard form of a call to Assign is

destination.Assign(source);

which tells the destination object to copy the contents of the source object to itself. In this method, all child objects are ignored. If you want to copy child objects, use the AssignAll(Base) method.

See Also

AssignAll(Base)

CanContain(Base)

Gets a value indicating that this object can contain the specified child object.

Declaration

public bool CanContain(Base child)

Parameters

Type	Name	Description
Base	child	Child object.

Type	Description
System.Boolean	true if this object can contain the specified child object; otherwise, false.

ClearRegisteredData()

Clears all registered data.

Declaration

public void ClearRegisteredData()

Creates unique alias for data item such as connection, datasource or relation.

Declaration

public string CreateUniqueAlias(string alias)

Parameters

Type	Name	Description
System.String	alias	The base alias.

Returns

Type	Description
System.String	The new unique alias.

Remarks

Use this method to create unique alias of the data item. It is necessary when you create new items in code to avoid conflicts with existing report items. This example show how to add a new table:

Report report1;
DataConnectionBase conn = report1.Dictionary.Connections.FindByName("Connection1");
TableDataSource table = new TableDataSource();
table.TableName = "Employees";
table.Name = report1.Dictionary.CreateUniqueName("EmployeesTable");

Declaration

public string CreateUniqueName(string name)

Parameters

Type	Name	Description
System.String	name	The base name.

Returns

Type	Description
System.String	The new unique name.

Remarks

Use this method to create unique name of the data item. It is necessary when you create new items in code to avoid conflicts with existing report items. This example show how to add a new parameter:

Report report1;
Parameter par = new Parameter();
par.Name = report1.Dictionary.CreateUniqueName("Parameter");
report1.Parameters.Add(par);
