如何在建议选择事件中从 c# 设置自动建议框的文本？

Question

我正在尝试从建议选择事件中隐藏的代码设置自动建议框的文本，但是这样做我的建议列表正在关闭，如果我将文本直接设置为模型名称，则建议列表不会正在关闭。

我想将自动建议框文本设置为模型属性，但如果我这样做，列表将关闭，我不想关闭此事件的建议列表。

另一方面，如果我将文本直接设置为型号名称，那么列表就不会显示 closed.I 我真的很困惑，无法让它发挥作用。

建议选择事件：

 private void recipient_SuggestionChosen(AutoSuggestBox sender, AutoSuggestBoxSuggestionChosenEventArgs args)
    {
        var getType = args.SelectedItem.GetType();
        if (getType.Name == "Table_People")
        {
            var selectedItemRecipient = args.SelectedItem as Table_People;
            //By doing this the list is getting closed.
            sender.Text = selectedItemRecipient.FirstName + " " + selectedItemRecipient.LastName;
            recipienterror.Visibility = Visibility.Collapsed;
            _personID = selectedItemRecipient.PersonID;
        }
        else
        {
            var selectedItemRecipientPlaces = args.SelectedItem as Table_Places;
            _placeID = selectedItemRecipientPlaces.PlaceID;
            //By doing this the list is getting closed.
            sender.Text = selectedItemRecipientPlaces.FirstName + " " + selectedItemRecipientPlaces.LastName;
            recipienterror.Visibility = Visibility.Collapsed;
        }

    }

提前致谢。

正如 tushargoyal1309 所说，您可以设置 TextMemberPath 属性以选择要在文本框中显示的数据对象属性。更多内容请参考AutoSuggestBoxclass官方文档

<AutoSuggestBox
     x:Name="asb"
     PlaceholderText="Type a name (e.g. John)"
     DisplayMemberPath="DisplayName"
     TextChanged="asb_TextChanged"               
     TextMemberPath="DisplayName"
     QueryIcon="Find"/>
