Definition

Caution

The System.Web.Mobile.dll assembly has been deprecated and should no longer be used. For information about how to develop ASP.NET mobile applications, see http://go.microsoft.com/fwlink/?LinkId=157231.

Provides a design-time type converter for a component's data field properties. For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.

Attributes

Remarks

The DataFieldConverter class is a TypeConverter object that is typically referenced by the TypeConverterAttribute attribute.

Note

You typically do not access a type converter directly. This implementation of TypeConverter is intended for use by a data-bound control at design time, and is instantiated with a TypeConverterAttribute on a property.

Constructors

DataFieldConverter()

Instantiates a new instance of the DataFieldConverter class. This API is obsolete. For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.

Methods

CanConvertFrom(ITypeDescriptorContext, Type)
