Diacritic Sensitivity in Xamarin ComboBox (SfComboBox)

13 May 20213 minutes to read

The control does not stick with one type of keyboard, so you can populate items from a language with letters containing diacritics, and search for them with English characters from an en-US keyboard. Users can enable or disable the diacritic sensitivity with the IgnoreDiacritic property. In the below code example we have illustrate how to enables the diacritic sensitivity so that items in the suggestion list get populated by entering any diacritic character of that alphabet.

NOTE

Diacritic Sensitivity support has enhanced only on iOS and Android platform.

XAML

<StackLayout VerticalOptions="Start" HorizontalOptions="Start" Padding="30">
    <combobox:SfComboBox  HeightRequest="40" x:Name="comboBox" IsEditableMode="True" AllowFiltering="True" TextHighlightMode="MultipleOccurrence" SuggestionMode="Contains" HighlightedTextColor="Red" IgnoreDiacritic="false">
        <combobox:SfComboBox.ComboBoxSource>
            <ListCollection:List x:TypeArguments="x:String">
                <x:String>Hów tó gâin wéight?</x:String>
                <x:String>Hów tó drâw ân éléphânt?</x:String>
                <x:String>Whéré cân I buy â câmérâ?</x:String>
