如何正确地通过混合代码(Windows Phone)来制作样式

Question

我混合了样式，看起来像这样，并

保留在此屏幕的xaml一侧，它看起来像这样：

 <phone:PhoneApplicationPage.Resources>
      <Style x:Key="TopinsStyle" BasedOn="{StaticResource PhoneButtonBase}" TargetType="ToggleButton">
            <Setter Property="Padding" Value="8"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ToggleButton">
                        <Grid Background="Transparent">

                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
 </phone:PhoneApplicationPage.Resources>

我需要动态添加togglebuttons，这是代码的一部分

foreach(dbDodatki z in choosenMeal.id_of_ingredients_object)
{
    ToggleButton tg = new ToggleButton();
    tg.Name = z.Ingredient_name_pl_pl;
    tg.Content = z.Ingredient_name_pl_pl;
    tg.Foreground = new SolidColorBrush(Color.FromArgb(255,22,65,38));
    tg.Background = new SolidColorBrush(Colors.White);
    tg.Style = App.Current.Resources["TopinsStyle"] as Style;
    tg.IsChecked = true;
    wrapWithBtns.Children.Add(tg);
}

但是我添加样式的方式不起作用。我找不到任何其他方法可以做到这一点

Answer 1

这是因为您将资源放在PhoneApplicationPage的资源中，但您正在尝试将其从应用程序资源中提取。

将样式放在应用程序资源中（适用于 wpf 应用程序的 App.xaml，不了解 Windows Phone 应用），或引用正确的资源。

假设后面的代码在PhoneApplicationPage中，它应该是：

tg.Style = this.Resources["TopinsStyle"] as Style;
