After the AdvancedTextBlock Captures property is bound, and then modify the Captures property data, the UI will not highlight the corresponding characters。

Hello,

The Captures property is not currently watching for any changes to the collection itself, only to changes to the Captures property value.  What kind of collection are you passing into the Captures property?

Similar to Visual Studio Solution search match highlighting, how would I achieve this?

Hello,

The AdvancedTextBlock.Captures property needs an enumerable of StringFilterCapture objects.  Each StringFilterCapture is an index/length set specifying the character range of the "captured" (highlighted) text in the AdvancedTextBlock.Text string value.

For my previous question, I meant what kind of collection Type are you binding to the AdvancedTextBlock.Captures property?  Is the Type something that implements INotifyCollectionChanged, such as an ObservableCollection<StringFilterCapture>?  Or is it another Type?

Our previous reply was indicating that we don't currently watch for INotifyCollectionChanged events on the collection bound to AdvancedTextBlock.Captures.  But we do update the captures if the property value of the AdvancedTextBlock.Captures property changes.
