I use a highlighting textbox control in my combo box DataTemplate that binds the highlighttext to the text of the comboBox which maybe is the problem. When I scroll down my combo box and it's virtualized, I get the correct non-highlighted regular textblock, but it will keep repeating the same highlighted textblocks. Basically, textbox TimeCodeName will be ok, but myapp:HighlightingTextBlock will be a repeat of the top 10.
I guess a few questions, is highlighting the matched text on the combo box going to be an option soon? Is there anyway to make this work with myapp:HTB? Is there any progress with filtering a virutalized combo box?
