# IListItem.Parent Property 
 
Gets/sets a parent [ThumbnailListView](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_ThumbnailListView.htm.md) control of this item.
 
**Namespace:** [Aurigma.GraphicsMill.WinControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_WinControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.WinControls (in Aurigma.GraphicsMill.WinControls.dll)
 
## Syntax
  
```
Property Parent As ThumbnailListView
```
 
```csharp
                ThumbnailListView Parent { get; set; }
```
 
### Property Value
 [ThumbnailListView](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_ThumbnailListView.htm.md) which is an owner of this item. If **null**, the item has no parent yet.
 
## Remarks
  
Internal architecture of the [ThumbnailListView](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_ThumbnailListView.htm.md) control requires all list item objects to belong not more than to to one control. Incorrect implementation of this property may lead to unpredictable results. You should not return **null** if the owner control is actually assigned.
 
Also, if it is necessary to dublicate the item into another [ThumbnailListView](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_ThumbnailListView.htm.md) control, you should clone list item rather than use a reference to it.
