When I set the ItemsSource of the RadTreeListView the first time after my silverlight 4 app has loaded. The tree is displayed correctly. Including expanded rows.
If I reload the data the first row is displayed expanded but without showing the subnodes. When I click the first row the arrow changes to collapsed. When I click to expand again, the first two lines are there but almost the rest of the RadTreeListView client region is white only the last two lines are displayed too. When I click on the second node to collaps, everything starts to work fine again.
I work with Version 2010.3.1110.1040.
