Examples

If you want to respond to the SuggestionsRequested event asynchronously, you must obtain a SearchSuggestionsRequestDeferral object before you edit the suggestion list. Here's an example that shows how.

public async static void SearchBox_SuggestionsRequested(
    SearchBox sender, 
    SearchBoxSuggestionsRequestedEventArgs args)
{

    // This object lets us edit the SearchSuggestionCollection asynchronously. 
    var deferral = args.Request.GetDeferral();

    try { 

        // Retrieve the system-supplied suggestions.
        var suggestions = args.Request.SearchSuggestionCollection;

        var groups = await SampleDataSource.GetGroupsAsync();
        foreach (var group in groups)
        {
            var matchingItems = group.Items.Where(
                item => item.Title.StartsWith(
                    args.QueryText, StringComparison.CurrentCultureIgnoreCase));

            foreach (var item in matchingItems)
            {
                suggestions.AppendQuerySuggestion(item.Title);
            }
        }

        foreach (string alternative in args.LinguisticDetails.QueryTextAlternatives)
        {
            if (alternative.StartsWith(
                args.QueryText, StringComparison.CurrentCultureIgnoreCase))
            {
                suggestions.AppendQuerySuggestion(alternative); 
            }
        }
    }
    finally {
        deferral.Complete();
    }

}

Remarks

Important

Although SearchBox is implemented in the Universal device family, it is not fully functional on mobile devices. Use AutoSuggestBox for your universal search experience. See SearchBox deprecated in favor of AutoSuggestBox.
