The two features in question seem to work on my end. Check the following demo
. I have recorded a small screencast
session on it. If I expand a node, the scroll position remains the same. If I select a node, then close the dropdown and open it again, the dropdown scroll position has not changed and the selected node is shown.
If this is not the test case you are describing, could you clarify it further? In addition, could you specify the exact Telerik UI for ASP.NET AJAX version used? The demo runs our latest version 2015.1 401. If you are using an older version, please test with our latest version.
