Hi Alex,
Thank you for reaching out to us.
I didn't manage to reproduce the problematic behavior. As you can see in the screenshot below, the Structure Highlighting feature recognizes namespace prefixed tag names correctly both in
.html
and.aspx
files on my side:Please share your CodeRush settings for further research. CodeRush stores its settings in two different locations:
%AppData%\CodeRush\Settings
folder;.cr
folder next to the.sln
file.Just pack both folders into an archive and share it with us using the comment form below.
I look forward to hearing from you.
Thanks for the response! I wasn't clear in my original post I am trying to change how the highlighting looks for the dx:BootstrapLayoutGroup tag in the editor window.


I was able to change it for the ContentCollection collection tag but when added trying to add dx:BootstrapLayoutGroup it won't accept it.
Hi Alex,
Thank you for clarifying this.
CodeRush doesn't support such a scenario because of the tag name validation mechanism. That is, after
Add Tag Name
button click CodeRush ensures that theHTML tag name
textbox's value contains a valid html tag name and since namespace prefixed tag names aren't allowed in the HTML standard - CodeRush does nothing. Tag names likedx:BootstrapLayoutGroup
are valid in the XHTML standard. Give me please additional time to discuss XHTML support for the Structural Formatting feature with the team.I will update this thread once we have news.
