ItemsElement

This element pages through a list of items and animates every item in and out on its own. Unlike ListElement, each item is drawn with a DataTemplate of your own, so an item can be anything from a single line of text to a complete grid.

Properties

Name
Type
Description

Items

IList

The items to display, usually coming from a source.

ItemsVisible

int

Number of items shown at the same time, which is one page. Default 5.

ChangeInterval

TimeSpan

How long a page is shown before the next one follows. Default 10 seconds.

PerItemDelay

TimeSpan

Delay added per item, so the items of a page animate one after another instead of all at once. Default 0.5 seconds.

Orientation

Enum

Vertical or Horizontal. Default Vertical. It is ignored once ItemsPanel is set.

ItemDataTemplate

DataTemplate

The template every item is drawn with.

ItemsPanel

ItemsPanelTemplate

The panel the items are arranged in. By default a StackPanel using Orientation.

ItemBackground

Brush

Background behind the items. Not set by default, which leaves them transparent.

AlternateItemBackground

Brush

Background behind every second item, for a striped list. Falls back to ItemBackground while it is not set.

StoryboardIn

Storyboard

Animation of an appearing item. By default it fades in.

StoryboardOut

Storyboard

Animation of a disappearing item. By default it fades out.

DataChangedMode

Enum

KeepPosition or StartFromBeginning, used when new data is set whose content is the same as before. Default KeepPosition.

DataContentChangedMode

Enum

KeepPosition or StartFromBeginning, used when new data is set whose content is different. Default StartFromBeginning.

DataChangedDelayMode

Enum

When data of the same content is applied: Now, AfterCurrentPage or AfterLastPage. Default AfterCurrentPage.

DataContentChangedDelayMode

Enum

When data of different content is applied: Now, AfterCurrentPage or AfterLastPage. Default Now.

SuppressFinished

Boolean

Keeps the element from raising its finished event after the last page. Default false.

ScrollEnabled

Boolean

Starts and stops the paging. It is a plain property, not a dependency property, so it cannot be bound.

Item backgrounds

ItemBackground and AlternateItemBackground paint the area an item is drawn in, behind the ItemDataTemplate. They alternate by the position on screen, not by the item, so the stripes stay where they are while the items page through them.

As long as neither is set, the items keep no background at all, which is what an overlay on top of a video usually wants. Setting only ItemBackground gives every item the same background.

New data

Whenever Items is set, the element first compares the new data with what is on screen, and then applies one of two pairs of properties:

Situation
When it is applied
Where it continues

The content is different

DataContentChangedDelayMode

DataContentChangedMode

The content is the same

DataChangedDelayMode

DataChangedMode

This way new results can appear immediately while an unchanged list simply keeps running.
