ITOCControlDefault Interface

Provides access to members that control the TOCControl.

Product Availability

Available with ArcGIS Engine.

Description

The ITOCControlDefault interface is the default dispatch interface that most development environments will automatically expose. For example, placing the TOCControl in a container will typically generate an object called TOCControl1. The properties and methods available directly on this object correspond to this interface, together with container specific properties and methods.

The ITOCControlDefault interface is a 'pure' dispatch interface, so can be extended with new properties and methods at future releases of ArcGIS. The methods and properties are identical to the highest numbered main interface on the TOCControl. For example, ITOCControlDefault is equivalent to ITOCControl2, but at future releases this could become ITOCControl3. By using the ITOCControlDefault interface you are guaranteed to always have access to the latest TOCControl. 

There is a small performance overhead in making calls through to a pure dispatch interface, but to avoid this you can QI to a specific interface. In some development environments it is not possible to QI directly on the control to other COM interfaces, because the control is contained within a wrapper object. Use the Object property to get the real control before performing the QI.

When querying interface to ITOCControlDefault in Visual Basic .NET or Visual C# .NET the Object property or container specific code must be used. This is because .NET contains the real control inside a wrapper object known as an host.

ITOCControlDefault tocControl=axTOCControl1.Object as ITOCControlDefault;
