ListView.TryDetach
TryDetach(int, out ItemView, Transform)
Transfers ownership of the ItemView representing the object at data source index sourceIndex from the ListView to the caller, allowing the caller to manipulate the listItem arbitrarily without fighting the ListView binding/prefab pooling system.
Remarks
If the detach succeeds, the listItem's parent will be set to newParent.
Because the now detached item is no longer a child of the ListView, the gesture handlers registered
on the ListView will not fire for the detached item anymore. To continue receiving the same events while the item is detached,
subscribe to them on the detached UIBlock directly (or its new parent) via AddGestureHandler<TGesture>(UIEventHandler<TGesture>, Boolean)
and then use RemoveGestureHandler<TGesture>(UIEventHandler<TGesture>) before TryReattach(ItemView) to avoid having multiple gesture handlers simultaneously.
Declaration
public bool TryDetach(int sourceIndex, out ItemView listItem, Transform newParent = null)Parameters
| Type | Name | Description |
|---|---|---|
| int | sourceIndex | The index of the object in the data source |
| ItemView | listItem | The list item visual reprensenting the object at index |
| Transform | newParent | The transform to set as the new parent of |
Returns
