Syntax
public class VisuallyInheritableList : ArrayListExt, IList, ICollection, IEnumerable, ICloneable
Remarks

A "visually inheritable list" is one that keeps track of and persists in code, the incremental changes applied on the list in a derived class's designer.

You should typically not use the methods and properties exposed by this class in your code. The properties are meant to be used during design-time to store the incremental changes done at design-time.

Constructors

VisuallyInheritableList()

Overloaded. Creates a new instance of the VisuallyInheritableList without any support for visual inheritance.

Declaration
public VisuallyInheritableList()

VisuallyInheritableList(IDesignable)

Creates a new instance of the VisuallyInheritableList with support for visual inheritance provided based on the specified parent's design state.

Declaration
public VisuallyInheritableList(IDesignable parent)
Parameters
Type Name Description
IDesignable parent

A reference to the IDesignable interface that typically contains this collection.
Remarks

This list keeps track of the incremental changes happening in a designer by following the parent's DesignMode property.

VisuallyInheritableList(Object[])

Creates a new instance of the VisuallyInheritableList class and inserts the items specified in the array into the VisuallyInheritableList without any support for visual inheritance.

Declaration
public VisuallyInheritableList(object[] items)
Parameters
Type Name Description
System.Object[] items

An array of objects.

Properties

DesignTimeChanges

Gets / sets the incremental changes done at design-time.

Declaration
public IntListDesignTime DesignTimeChanges { get; set; }
Property Value
Type
IntListDesignTime

Parent

Gets / sets the associated parent.

Declaration
public IDesignable Parent { get; set; }
Property Value
Type
IDesignable

Methods

GetDesignTimeChanges()

Returns a list representing the incremental changes made at design-time.

Declaration
protected virtual IntListDesignTime GetDesignTimeChanges()
Returns
Type Description
IntListDesignTime

A list representing the new position of the items based on the position of the items in the base class.
Remarks

This list will be provided in a call to SetDesignTimeChanges(ArrayList) to reapply the changes done during this design-time.

IsIdenticalObjects(Object, Object)

Compares two objects for equality.

Declaration
protected virtual bool IsIdenticalObjects(object item1, object item2)
Parameters
Type Name Description
System.Object item1

Object 1.
System.Object item2

Object 2.
Returns
Type Description
System.Boolean

True if identical; False otherwise.
Remarks

The base class version uses the "==" operator to perform the comparison. This could be overridden to support boxed types (int, for example), where 2 integers should be compared based on their value rather than the boxed object instance.

OnCollectionChanged(CollectionChangeEventArgs)

Declaration
protected override void OnCollectionChanged(CollectionChangeEventArgs args)
Parameters
Type Name Description
System.ComponentModel.CollectionChangeEventArgs args
Overrides

OnCollectionChanging()

Overridden. See Syncfusion.Collections.ArrayListExt.OnCollectionChanged.

Declaration
protected override void OnCollectionChanging()
Overrides

ReinitBaseClassCopy()

Declaration
public void ReinitBaseClassCopy()

SetDesignTimeChanges(ArrayList)

Called to apply the changes made in the previous design-time invoke.

Declaration
protected virtual void SetDesignTimeChanges(ArrayList newPositionList)
Parameters
Type Name Description
System.Collections.ArrayList newPositionList

A list specifying the new positions based on the positions of the exisiting items set in the base class.

ShouldContinueIfItemsCountChanged()

Indicates whether to continue applying incremental-changes done in the previous design-time invocation.

Declaration
protected virtual bool ShouldContinueIfItemsCountChanged()
Returns
Type Description
System.Boolean

True to continue; False otherwise.
Remarks

This method is called if it seems like items were removed in the base class since the last invoke of this design-time.

Implements

System.Collections.IList
System.Collections.ICollection
System.Collections.IEnumerable
System.ICloneable
