Background-highlighting all string tokens equal to selected

Hello,

That sounds like custom functionality your team may have built into usage of the older version.  Did you use span indicators in the old version to accomplish that?

You can achieve background highlighting using a classification tagger in the new version.  You effectively "tag" (mark) a text range using a certain classification type.  That classification type is registered with the ambient highlighting style registry to have a related highlighting style that has a background color.  The "Adornments - Highlight Word" QuickStart is a good example of using a classification tagger to highlight text ranges.

We also have another QuickStart added in the upcoming version called "Adornments - Highlight Ranges" where it shows how you can select a range and press a button to add a background highlight over that range.  That's effectively what you'd want to do here, but over the text ranges that your variable falls on.

Thank you, we will check deeper in what made it work.

Thanks again for the leads, yes, it turns out, we were indeed using span indicators in the previous version after selection changed event.

Following your recommendation, in the new version, we are able to extend TaggerBase and register it as a TextViewTaggerProverder, tapping the same .SelectionChanged event.

We are using .GetCurrentWordText for the "gray" single click select and .SelectedText for the "light blue" select following double-click to preserve this for our users that are used to double-clicking.

thanks.
