Attributes: ObsoleteAttribute

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 This API is obsolete.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)	Gets a value indicating whether the specified source type can be converted to the type of the associated control property. This API is obsolete. For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.
CanConvertFrom(Type)	Returns whether this converter can convert an object of the given type to the type of this converter. (Inherited from TypeConverter)
