C# 在代码隐藏中设置控件的StaticResource样式
比方说,我有这样的东西(在MainPage.xaml中):C# 在代码隐藏中设置控件的StaticResource样式,c#,xaml,windows-phone-8,windows-phone-8.1,C#,Xaml,Windows Phone 8,Windows Phone 8.1,比方说,我有这样的东西(在MainPage.xaml中): 你可以设置,像这样的 TextBlock myTextBlock= new TextBlock () { FontFamily = new FontFamily("Segoe UI Light"); Style = Resources["TextBlockStyle"] as Style, }; 您可以使用以下选项: Style textBlockStyle; try { t
你可以设置,像这样的
TextBlock myTextBlock= new TextBlock ()
{
FontFamily = new FontFamily("Segoe UI Light");
Style = Resources["TextBlockStyle"] as Style,
};
您可以使用以下选项:
Style textBlockStyle;
try
{
textBlockStyle = FindResource("TextBlockStyle") as Style;
}
catch(Exception ex)
{
// exception handling
}
if(textBlockStyle != null)
{
myTextBlock.Style = textBlockStyle;
}
或TryFindResource
方法:
myTextBlock.Style = (Style)TryFindResource("TextBlockStyle");
这个问题已经问了4年多了,但我想发布一个答案来分享我的发现 例如,如果在
App.xaml
(Xamarin跨平台应用程序开发)中的应用程序资源中描述了样式
蓝色按钮
,则可以如下使用
<?xml version="1.0" encoding="utf-8" ?><Application xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="SharedUi.App">
<Application.Resources>
<ResourceDictionary>
<Style x:Key="BlueButton" TargetType="Button">
<Setter Property="TextColor" Value="White" />
<Setter Property="FontSize" Value="20" />
<Setter Property="BackgroundColor" Value="Blue"/>
<Setter Property="HeightRequest" Value="70"/>
<Setter Property="FontAttributes" Value="Bold"/>
</Style>
</ResourceDictionary>
</Application.Resources></Application>
我知道这很古老,但是有人知道如何使用FrameworkElementFactory(typeof(TextBlock))做同样的事情吗?我只把这些调用看作是Android特定的API。
myTextBlock.Style = (Style)TryFindResource("TextBlockStyle");
<?xml version="1.0" encoding="utf-8" ?><Application xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="SharedUi.App">
<Application.Resources>
<ResourceDictionary>
<Style x:Key="BlueButton" TargetType="Button">
<Setter Property="TextColor" Value="White" />
<Setter Property="FontSize" Value="20" />
<Setter Property="BackgroundColor" Value="Blue"/>
<Setter Property="HeightRequest" Value="70"/>
<Setter Property="FontAttributes" Value="Bold"/>
</Style>
</ResourceDictionary>
</Application.Resources></Application>
Button newButton1 = new Button
{
Text = "Hello",
WidthRequest = (double)15.0,
Style = (Style)Application.Current.Resources["BlueButton"]
};
