ICustomTypeDescriptor Interface

Definition

Namespace:

System.ComponentModel

Assembly:

System.ComponentModel.TypeConverter.dll

Provides an interface that supplies dynamic custom type information for an object.

public interface class ICustomTypeDescriptor

public interface ICustomTypeDescriptor

type ICustomTypeDescriptor = interface

Public Interface ICustomTypeDescriptor

Derived

System.Activities.DynamicActivity

System.Activities.DynamicActivity<TResult>

System.Activities.Statements.Interop

System.ComponentModel.CustomTypeDescriptor

System.Data.Common.DbConnectionStringBuilder

System.Data.Common.DbDataRecord

System.Data.DataRowView

System.Web.UI.WebControls.SubMenuStyle

System.Web.UI.WebControls.WebParts.WebPartMenuStyle

System.Windows.Forms.AxHost

Remarks

The ICustomTypeDescriptor interface allows an object to provide type information about itself. Typically, this interface is used when an object needs dynamic type information. In contrast, the TypeDescriptor class provides static type information that is obtained from metadata.

For example, ICustomTypeDescriptor is used in the .NET Framework to provide type information for COM objects. COM objects do not support properties or attributes. Therefore, the .NET Framework uses ICustomTypeDescriptor to implement properties and attributes for COM objects.

To provide dynamic custom type information, a class can implement ICustomTypeDescriptor or derive from the CustomTypeDescriptor class, which provides a simple implementation of this interface.

Note

There is no design-time support for data binding to objects that implement the ICustomTypeDescriptor interface. In addition, when binding to a runtime instance of ICustomTypeDescriptor, the public properties of the underlying type are ignored.
