我有一個UWP應用程序,它有一系列帶有點擊事件的按鈕。我也有一個文本框,我需要專注於應用程序的幾乎每次點擊/觸摸。所以我設置了這樣的resetFocus功能:獲取lostfocus事件上的點擊按鈕
public void resetfocus2(object sender, RoutedEventArgs e)
{
Username.Focus(FocusState.Programmatic);
}
觸發此文本框外的每次點擊。
這是XAML
<ListView>
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Margin="4" Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<Button Tag="{Binding id}" Grid.Column="0" Padding="0" BorderThickness="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="100" Background="White" Click="Meal1_Click">
<Image Width="100" Height="100" Source="{Binding idImg}" RelativePanel.AlignLeftWithPanel="True" />
</Button>
</StackPanel>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
我的問題按鈕是:
我怎麼能叫正常調用這個函數內的按鈕,點擊該功能?
由於lostfocus事件發生在點擊和點擊功能從未觸發之前。
UPDATE: 這是從按鈕創建對話框代碼:
public async void Meal1_Click(object sender, RoutedEventArgs e)
{
ServiziSoapClient service = new ServiziSoapClient();
var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
var mealresponse = await service.SERVICE("PASSWORD", (sender as Button).Tag.ToString(), (string)localSettings.Values["stabilimento"]);
var response = JsonValue.Parse(mealresponse.Body.SERVICE).GetObject();
var notnull = 0;
try
{
var temp = response.GetNamedArray("OPTION");
}
catch (Exception exc)
{
Debug.WriteLine("Exception " + exc.Message);
notnull = 1;
}
JsonArray allergeni = null;
var piatto = response.GetNamedObject("OPTION2");
if (notnull == 0)
allergeni = response.GetNamedArray("OPTION");
var ingredienti = response.GetNamedString("OPTION3");
var btn = sender as Button;
var dialog = new ContentDialog()
{
Title = piatto.GetNamedString("descr"),
//RequestedTheme = ElementTheme.Dark,
//FullSizeDesired = true,
MaxWidth = this.ActualWidth // Required for Mobile!
};
// Setup Content
var panel = new StackPanel();
var defaultImageUri = new Uri("ms-appx:///Images/ic_placeholder_primi.png");
var bitmap = new BitmapImage();
bitmap.ImageFailed += (s, ex) => bitmap.UriSource = defaultImageUri;
bitmap.UriSource = new Uri("http://test-wsmensa.sinergest.it//WS/getImage.ashx?GETIN=B&&@[email protected]&ID_IMMAGINE=" + piatto.GetNamedNumber("idImg") + "&HEIGHT=100", UriKind.Absolute);
panel.Children.Add(new Image
{
Height = 400,
Width = 400,
Source = bitmap
});
panel.Children.Add(new TextBlock
{
TextWrapping = TextWrapping.Wrap,
FontSize = 20,
Text = "Ingredienti: " + ingredienti
});
dialog.Content = panel;
dialog.PrimaryButtonText = "Chiudi";
// Show Dialog
var result = await dialog.ShowAsync();
UserName.Focus(FocusState.Programmatic);
}
不知道UWP是否也有這個功能,但在常規的WPF中,我只是在按鈕上設置了'Focusable =「False」'。這樣你的文本框就不會失去焦點。 –
