Properties

ItemContainerTemplateSelector

The IItemContainerTemplateSelector that creates UI controls for bar control view models.

protected override Type StyleKeyOverride { get; }

Property Value

Type

Remarks

Usually controls are styled by their own type, but there are instances where you want an element to be styled by its base type, e.g. creating SpecialButton that derives from Button and adds extra functionality but is still styled as a regular Button. Override this property to change the style for a control class, returning the type that you wish the elements to be styled as.

Methods

ClearContainerForItemOverride(Control)

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.

bool:

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

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
