I am creating a TreeView at runtime. It has several nodes(TreeViewItem), each one having a name. Initially it is collapsed. A separate comboBox displays Names of all TreeViewItem. I have to highlight a TreeViewItem based on the Name selected. I am using a recursive function and gets the TreeViewItem container like this:

if (parent.ItemContainerGenerator.Status != GeneratorStatus.ContainersGenerated)
                continue;

TreeViewItem container = parent.ItemContainerGenerator.ContainerFromItem(child).As<TreeViewItem>();

but it is

parent.ItemContainerGenerator.Status = GeneratorStatus.NotStarted

for all the collapsed items. How can I generate containers for them manually(Without expanding them)?
