Looks like you are using a tree structure in your file.
I found XTreeBehavior in Yii Playground to be the best.
You can download it from Github - I think.
The only difference:
You stated "Root pages have a parent_page of 0."
That will have to change to "Root pages have a parent_page of null.", because the behavior uses a relation in the database between the child and parent records. But this relation saves you lots of effort.
Thanks for your help. I ended up using XTreeBehavior; but not for this since it’s mostly geared towards using CTreeView. It does have some awesome methods like getBreadcrumbs and deleteKeepChildren. I rolled my own simple solution using a CArrayDataProvider.

return $this;

* @return CArrayDataProvider the data provider that can return the models based on the search/filter conditions.

{
$rawData = $this->getSearchData(Page::model()->root()->with('children')->findAll(array(
'order' => 't.title'

return new CArrayDataProvider($filteredData, array(
'id' => 'id',
'sort' => array(
'attributes' => array(
//'title', // We don't allow sorting on title because
// it'll break the parent/child link and confuse the user.
'status'
),
),
'pagination' => array(
'pageSize' => 10,

));
}

{
foreach ($nodes as $node)
{
// These fields are used by a grid.
$rawData[$node->id]['id'] = $node->id;
$rawData[$node->id]['title'] = $node->getIndentedPageLevel();

if ($node->childCount > 0)
$rawData = $this->getSearchData($node->myChildren($node)->findAll(array('order' => 't.title')), $rawData);
}
return $rawData;

$model = new Page('search');
