GetStandardValuesExclusive Method (ITypeDescrip...
.NET Framework Class Library
TypeConverter..::.GetStandardValuesExclusive Method (ITypeDescriptorContext)

Returns whether the collection of standard values returned from GetStandardValues is an exclusive list of possible values, using the specified context.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)
Visual Basic (Declaration)
Public Overridable Function GetStandardValuesExclusive ( _
    context As ITypeDescriptorContext _
) As Boolean
Visual Basic (Usage)
Dim instance As TypeConverter
Dim context As ITypeDescriptorContext
Dim returnValue As Boolean

returnValue = instance.GetStandardValuesExclusive(context)
C#
public virtual bool GetStandardValuesExclusive(
    ITypeDescriptorContext context
)
Visual C++
public:
virtual bool GetStandardValuesExclusive(
    ITypeDescriptorContext^ context
)
JScript
public function GetStandardValuesExclusive(
    context : ITypeDescriptorContext
) : boolean

Parameters

context
Type: System.ComponentModel..::.ITypeDescriptorContext
An ITypeDescriptorContext that provides a format context.

Return Value

Type: System..::.Boolean
true if the TypeConverter..::.StandardValuesCollection returned from GetStandardValues is an exhaustive list of possible values; false if other values are possible.

As implemented in this class, this method always returns false.

If the list is exclusive, such as in an enumeration data type, then no other values are valid. If the list is not exclusive, then other valid values might exist in addition to the list of standard values that the GetStandardValues method provides. If the values are exclusive, the list returned by GetStandardValues should not allow these values to be edited.

Notes to Inheritors:

Override this method if the type you want to convert supports standard values.

Use the context parameter to extract additional information about the environment from which this converter is invoked. This parameter can be nullNothingnullptra null reference (Nothing in Visual Basic), so always check it. Also, properties on the context object can return nullNothingnullptra null reference (Nothing in Visual Basic).
