Hi,
I'm using TreeView with the checkbox enabled
So the basic usage:
The treeview has no checked items to begin with and is collapsed. The user should be able to check the top item.
So the problem is that I cannot iterate through the checked item collection when the tree is collapsed because the items do not exist.
Is there any way to have the items created so I can iterate through them without expending the tree.
Best regards
Kristján.

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.
Kind regards,
