如何将treelistcontrol滚动到选中的项?

is it possible to scroll the treelistcontrol to the selected item. so that selected items are always in view. I am programmatically selecting nodes using the call to SelectItem(nodeToSelect) by extending the treelistcontrol. A code snippet or a sample would be very helpful.

是否可以将treelistcontrol滚动到所选项。所以所选的项目总是可见的。通过扩展treelistcontrol，我使用对SelectItem(nodeToSelect)的调用以编程方式选择节点。代码片段或示例将非常有用。
