Class DefaultChildTypeAttribute

Attribute used to specify the default child type for a parent type.

Inheritance

System.Object

DefaultChildTypeAttribute

Namespace: Syncfusion.Windows.Forms.Design

Assembly: Syncfusion.Shared.Base.dll

Syntax

public class DefaultChildTypeAttribute : Attribute

Remarks

A parent type designer, say TabControl for example, usually lets you add child types, TabPage in this case, during design-time. However, when you create custom types deriving from TabControl and TabPage, the designer needs to be informed about this change in "default child type" for your derived parent type. This attribute lets you declare this relationship.

Some of our components like TabControlExt and XPTaskBar use this attribute to declare their default child type. Their corresponding designers query this attribute before creating a new child instance. This way, when you derive custom types for the above Controls, you can specify the new default child type using this attribute on your parent type.
