With our Q3 2014 SP1 release an exception is thrown when you try to maximize an Item. 

Available in LIB version: 2015.1.1208

When you add RadBook as a content of RadTileViewItem and reorder the TileViewItem you get ArgumentOutOfRangeException.

Workaround: You can set the width of the RadBook.

Workaround:
Create a custom style which target type is set to TileViewItemHeader and set it to the HeaderStyle property of the TileView. Then in the custom style, set a custom DataTemplate to the HeaderTemplate property. In this template specify a TextBlock and set its Margin property for instance.

Available in R3 2017 Official Release Version.

The values are switched. 

NewState holds the value of OldState. 
OldState holds the value of NewState 

Reproduced with Implicit Styles with NoXAML binaries only. The workaround is to set a fixed value for the RestoredHeight property of RadTileViewItem

The UnselectAll method, which comes from MultiSelector, does not unselect all items when manually select them one by one. The method will unselect the items in the order they were selected, one by one.

Introduce support for specifying the speed of the auto-scrolling functionality (when the IsAutoScrollingEnabled property is set to True).

Dear Telerik Development Team,

First of all, I want to thank you for your great work on the RadTileView control for WPF. I appreciate the effort and attention to detail that you have invested in this component.
In my projects, RadTileView has brought significant value thanks to its visual appearance, the smooth animation when maximizing or restoring tiles, and the ability to provide distinct content for minimized and maximized states. It truly enhances the user experience, and I find the dynamic layout engaging and modern.

However, I have faced some challenges related to tile reordering and positioning:

• The drag & drop rearrangement mechanism sometimes behaves in unpredictable or unintuitive ways, especially when there are many tiles or when tiles have different sizes.

• There is currently no straightforward way to specify the exact row and column position of each tile when dynamically adding them from code.

• It would be extremely useful to have a way to control or "lock" a tile to a specific grid position, for example by exposing explicit row and column properties for each tile, or by allowing developers to define the exact layout coordinates when adding tiles dynamically. This feature would make it possible to programmatically manage tile placement in complex dashboards, rather than relying only on the automatic layout and drag & drop interactions.

Such functionality would be highly beneficial in many scenarios, especially for enterprise dashboards where the layout must follow strict business requirements and should not be left to chance or automatic algorithms.

Would it be possible to consider this kind of feature for a future release?
If there is a known workaround or recommended approach to achieve precise tile positioning with the current RadTileView, I would greatly appreciate your guidance.

Thank you again for your work and support.
Looking forward to your reply!

Best regards,
