Hi,
I'm using RadTreeView with collections, where both parent and child elements are bound to: CollectionViewSource. This allows the bound collections to be easily sorted. The problem is occurs when:
1. Filter out the child collection
2. Select parent item (the parent item and all visible children get checked)
3. Remove filter - the parent item stills is in checked state (instead of undeterminate).
Best regards

Hello Marcin,
I am not sure that I fully understand your scenario. Can you please elaborate more on your current implementation. Also can you please clarify what is the issue that you observe and report (with video, images, snippets).
It will be best if you can reproduce the reported behavior in a separate project and attach it to a support ticket that can be opened from your Telerik account.

As I cannot attach sample project here, and this is not a bug, that require opening support ticket, please download the sample project from here:
https://dl.dropboxusercontent.com/u/16374949/CheckBoxesSample.zip
It's not a big bug, but maybe You would like to fix it in future releases ;)
Enter some text in the top text box (e.g. Modi). Then check the remaining child element. Then remove the filter text ;) The parent element's check state remains "checked" instead of changing to undeterminate...

Hello Marcin,
Thank you for providing us with detailed information about your scenario. Now I understand your issue. You need to keep in mind that the tri-state logic of the RadTreeView control is designed to work with XAML defined control and items, only. In case that your scenario implements MVVM you can use the approach described in this article.
Please take a look at it and let me know if it works for you.
