範例
如果您想要以非同步方式回應 SuggestionsRequested 事件,您必須先取得 SearchSuggestionsRequestDeferral 物件,才能編輯建議清單。 以下是示範方式的範例。
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();
}
}
備註
重要
雖然 SearchBox 可在通用裝置系列中實作,但在行動裝置上無法使用所有功能。 請將 AutoSuggestBox 用在您的通用搜尋經驗。 請參閱 SearchBox 已取代為 AutoSuggestBox。
