inactive selected text background

Hi Andrew,

Sorry but I'm not seeing that, at least when trying in the latest version.  Setting that property, I see the selection change color to it when it's inactive.

Are you able to reproduce this in one of our samples?

Darn, in the Sample Browser for that version it works. OK, sorry for the mistake!

Hi Andrew,

Note that if you have an IHighlightingStyle registered in your highlighting style registry for DisplayItemClassificationTypes.InactiveSelectedText, that can also change the brush used.

I figured it out! there is actually a bug in my Actipro version that disables the inactive selected text color when IsMultiLine = False. Do you know if this still happens in the latest version? I've been reluctant to upgrade for this app because I got the look and feel just right with the earlier library.

Hi Andrew,

Aha... When in single-line mode, it tries to act like a normal TextBox that doesn't show the selection when unfocused.  Nothing has changed with that in the latest version since it is by design.

Oh no, will I have to make a custom highlighting style to mimic the inactive selected text in that case?

No, the inactive selected text brush, whether set via SyntaxEditor.InactiveSelectedTextBackground or via an IHighlightingStyle associated with the classification type DisplayItemClassificationTypes.InactiveSelectedText, will only display when SyntaxEditor is multi-line mode.  It is ignored in single-line mode, since SyntaxEditor doesn't render an inactive selection background in that mode.

Sorry, I meant a custom tagger that follows the current selection span and marks it with a brush that stays when the control is unfocused.

Yes, you could do that kind of thing if needed.

Sounds good! May I suggest a new property based on https://docs.microsoft.com/en-us/dotnet/api/system.windows.controls.primitives.textboxbase.isinactiveselectionhighlightenabled?redirectedfrom=MSDN&view=net-5.0#System_Windows_Controls_Primitives_TextBoxBase_IsInactiveSelectionHighlightEnabled

Thanks again for the inside info.

Thanks for the suggestion, we'll make a note of it.
