在多次运行的WPF文本块中,如何将样式应用于特定样式
本文关键字:样式 应用于 运行 WPF 文本 | 更新日期: 2023-09-27 18:20:01
如何不在整个文本块上应用样式,而仅在第一次运行时应用样式(粗体)?
我想在粗体Run上应用样式"XXXFontName Bold",在其余部分应用样式"XXXXFontName Thin"。
// add button
Button btn = new Button();
TextBlock contextText = new TextBlock();
contextText.Inlines.Add(new Bold(new Run(label.Substring(0,1))));
contextText.Inlines.Add(new Style()); <===== OBVIOUS ERROR HERE
contextText.Inlines.Add(label.Substring(1));
contextText.FontSize = 25;
contextText.Style = FindResource("XXXFontName-Thin") as Style;
btn.Content = contextText;
3示例样式,使用样式和新行在XAML中设置运行的示例,以及如何在按钮的代码后面设置它们
你的代码背后:
public MainWindow()
{
InitializeComponent();
Button btn = new Button();
TextBlock contextText = new TextBlock();
var newRun = new Run("BoldGreenRunStyle");
newRun.Style = FindResource("BoldGreenRunStyle") as Style;
contextText.Inlines.Add(newRun);
newRun = new Run("ItalicRedRunStyle");
newRun.Style = FindResource("ItalicRedRunStyle") as Style;
contextText.Inlines.Add(newRun);
newRun = new Run("ThinPurpleRunStyle");
newRun.Style = FindResource("ThinPurpleRunStyle") as Style;
contextText.Inlines.Add(newRun);
btn.Content = contextText;
Container.Children.Add(btn);
}
您的XAML
