I am attempting to update our application to the latest release, and I am having serious trouble tracking down the compatibility issue that is causing this style which functioned normally in 2011 and 2012, but jacks up our view using the 2013 release. Advice from anyone who can take a look with knowing eyes would be greatly appreciated.

Hello Adam,

I tried your snippet out and it seems that some resources are missing. Also, the template called "ToggleButtonGlassTemplate" will be needed in order to see the issue that you report. Can you please change the attached project so that I will be able to run it (and see the issue that you report) on our side and send it over. Also, it will be great if you make a picture of your layout and clarify which alignments are not desired.

Thank you for your cooperation. I am looking forward to hearing from you.

The first block is the ToggleButtonGlassTemplate.xaml you asked for and the second is our Brushes.xaml. Strangely, I was hoping it was just something obvious I was missing. I have also attached a picture of what the control looked like using both releases. I modified your project but I didn't realize I wouldn't be able to attach a zip here. Thanks for your help, I really appreciate it!

TreeViewItem-CustomStyle.zip

Hello Adam,

Thank you for providing me with more information. As I can see in your code, you applied a custom style to the ToggleButton which expands/collapses the RadTreeViewItem and you have wrapped it in a Border element. This is why I decided to extract the latest template of the RadTreeViewItem and apply your custom style to that button. Visually the second level item looks like the item from your picture. Furthermore, you can use ItemTemplateSelector to apply different styles to items from different levels (e.g. the root item).

Please take a look at the attached project and let me know if it works for you.
