Methods

ClearContainerForItemOverride(Control)

Undoes the effects of the PrepareContainerForItemOverride(Control, object, int) method.

protected override void ClearContainerForItemOverride(Control container)
Parameter Type Description
container Control

The container element.

CreateContainerForItemOverride(object?, int, object?)

Creates or a container that can be used to display an item.

protected override Control CreateContainerForItemOverride(object? item, int index, object? recycleKey)
Parameter Type Description
item object
index int
recycleKey object

Returns

Control

NeedsContainerOverride(object?, int, out object?)

Determines whether the specified item can be its own container.

protected override bool NeedsContainerOverride(object? item, int index, out object? recycleKey)
Parameter Type Description
item object

The item to check.
index int

The index of the item.
recycleKey object

When the method returns, contains a key that can be used to locate a previously recycled container of the correct type, or null if the item cannot be recycled. If the item is its own container then by definition it cannot be recycled, so recycleKey shoud be set to null.

Returns

bool:

true if the item needs a container; otherwise false if the item can itself be used as a container.

OnApplyTemplate(TemplateAppliedEventArgs)

Called when the control's template is applied. In simple terms, this means the method is called just before the control is displayed.

protected override void OnApplyTemplate(TemplateAppliedEventArgs e)
Parameter Type Description
e TemplateAppliedEventArgs

The event args.

OnCreateAutomationPeer()

Returns a new, type-specific Avalonia.Automation.Peers.AutomationPeer implementation for the control.

protected override AutomationPeer OnCreateAutomationPeer()

Returns

AutomationPeer:

The type-specific Avalonia.Automation.Peers.AutomationPeer implementation.

PrepareContainerForItemOverride(Control, object?, int)

Prepares the specified element to display the specified item.

protected override void PrepareContainerForItemOverride(Control container, object? item, int index)
Parameter Type Description
container Control

The element that's used to display the specified item.
item object

The item to display.
index int

The index of the item to display.
