.NET Framework Class Library

BindingList<(Of <(T>)>)..::.ApplySortCore Method

Sorts the items if overridden in a derived class; otherwise, throws a NotSupportedException.

Namespace: System.ComponentModel
Assembly: System (in System.dll)

Syntax

Visual Basic (Declaration)

Protected Overridable Sub ApplySortCore ( _
    prop As PropertyDescriptor, _
    direction As ListSortDirection _
)

Visual Basic (Usage)

Dim prop As PropertyDescriptor
Dim direction As ListSortDirection

Me.ApplySortCore(prop, direction)

protected virtual void ApplySortCore(
    PropertyDescriptor prop,
    ListSortDirection direction
)

Visual C++

protected:
virtual void ApplySortCore(
    PropertyDescriptor^ prop, 
    ListSortDirection direction
)

JScript

protected function ApplySortCore(
    prop : PropertyDescriptor, 
    direction : ListSortDirection
)

Parameters

prop: Type: System.ComponentModel..::.PropertyDescriptor
A PropertyDescriptor that specifies the property to sort on.

direction: Type: System.ComponentModel..::.ListSortDirection
One of the ListSortDirection values.

Exceptions

Exception	Condition
NotSupportedException	Method is not overridden in a derived class.

Remarks

The BindingList<(Of <(T>)>) class does not provide a base implementation of sorting, so ApplySortCore always throws a NotSupportedException by default. To enable sorting, derive from BindingList<(Of <(T>)>) and perform the following tasks:

Override ApplySortCore and implement sorting, raising the ListChanged event when sorting is complete.
Override RemoveSortCore and implement sort removal.
Override SupportsSortingCore and set SupportsSortingCore to true.

In addition, you may want to implement the supplemental SortDirectionCore and SortPropertyCore sorting properties.
