) As Boolean
public virtual bool CanConvertFrom(
ITypeDescriptorContext context,
Type sourceType
)
Parameters
- context
Type: System.ComponentModel.ITypeDescriptorContext

Type: System.Type
The type you want to convert from.
Return Value
Type: System.Boolean

Remarks
Notes to Inheritors
For use as a type converter for custom-type attribute handling in Silverlight XAML, you should define the CanConvertFrom(ITypeDescriptorContext, Type) signature with your implementation. Return true if sourceType is of type String; otherwise, false. Do not rely on information in context, it may be nulla null reference (Nothing in Visual Basic). Do not throw if context is nulla null reference (Nothing in Visual Basic); the other signature (CanConvertFrom(Type)) calls this one, passing a null context.
The base implementation always returns false.
