> **Removed.** TreeView is now deprecated. You can likely now use TreeView\\\<int\\> instead and not think more about it. But if you were using that identifier to store InstanceID data, you should instead opt to upgrade your TreeViews to use TreeView\\\<InstanceID\\> to get the proper typing.

```csharp
public bool BeginRename(TreeViewItem item)
```

### Parameters
