|---|---|
Gets the diagram item that is being realized or virtualized. | |
Gets the UI element that represents a diagram item. | |
Gets the root visual of the item's graphics representation. It is the result of DiagramItem.CreateRenderer, e.g. an instantiation of a data template. |
RemarksYou can handle the ItemVirtualized event to perform cleanup when an item's visual element is being removed from the visual tree. This is typically used to detach any event handlers or release resources that were attached during ItemRealized. Failing to do so may result in memory leaks.
