Hello Abdulrahman Omran,
The issue in the RadTreeView is fixed and you can inspect it in the internal build 0411. Please let us know if you have tried this internal build and the problem has not gone.
On the other hand, there is an issue when typing in textbox located in RadTileViewItem. Is your problem related ? This is also fixed but will be included in the official SP1 scheduled for this week.
Please accept our apologies for any inconvenience caused.
