Hello Kristjan Einarsson,
As you said you can't iterate through the item containers because they are still not generated.
Can you elaborate a little bit more on the problem you are trying to solve? Basically the correct implementation will be if you think of the TreeView only as a View of your data model
, and to iterate not the generated treeview items, but the business objects that are used for the treeview population. This way you will have access to all the items - not only to generated containers.
