我想在 Silverlight 应用程序中显示文本,以便用户可以在其他地方复制并粘贴(就像用于 HTML < / strong>网站)。
如果我使用 TextBlock ,则用户无法复制和粘贴。
因此我使用 TextBox ,但它上面有默认边框。我可以删除 BorderThickness="0"
边框,如下所示:
<TextBox
Grid.Column="1"
BorderThickness="0"
Text="{Binding ViewModelBindingStringsBlockHelp}"/>
效果很好:

但是,当用户悬停在文本框上选择文字时,会出现另一个边框:
alt text http://www.deviantsart.com/upload/1k7m44p.png
我发现purported solutions用于删除此边框,但令人难以置信地需要页面的XAML。
我正在寻找像这样的简单解决方案:
HoverBorderThickness="0"
在Silverlight TextBox上隐藏悬停边框的简单方法是什么?

不幸的是,你曾经遇到过想要做一些复杂似乎相对简单的事情的事情,但是你必须跳过一些箍来做这件事。如前面的答案所述,将需要重新设置/重新模板文本框。
至于悬停状态 - 这是你应该掌握的相对较大的Silverlight点 - 它的想法是每个控件都有单独的状态。
Expression Blend是处理这些状态的绝佳方式 - 您可以轻松查看内置XAML模板和样式的内容,并且可以轻松地即时编辑它们。有时可能会很棘手,而且肯定会让你的XAML变得有点笨重,但这就是你需要它来控制做你想做的事情所花费的成本。强>
利用国家的力量 - 特别是在Blend中 - 我保证你会意识到你的生活会变得多么容易。

这是我创建没有背景和边框的只读文本框的解决方案:
public class MyTextBox : TextBox
{
private String readOnlyText;
public String ReadOnlyText
{
get
{
return readOnlyText;
}
set
{
readOnlyText = value;
this.Text = readOnlyText;
}
}
public MyTextBox()
{
BorderThickness = new Thickness(0);
Background = new SolidColorBrush(Color.FromArgb(0, 255, 255, 255));
BorderBrush = new SolidColorBrush(Color.FromArgb(0, 255, 255, 255));
this.TextWrapping = System.Windows.TextWrapping.Wrap;
this.GotFocus += new RoutedEventHandler(MyTextBox_GotFocus);
this.MouseEnter += new MouseEventHandler(MyTextBox_MouseEnter);
this.MouseMove += new MouseEventHandler(MyTextBox_MouseMove);
this.TextChanged += new TextChangedEventHandler(MyTextBox_TextChanged);
}
void MyTextBox_TextChanged(object sender, TextChangedEventArgs e)
{
if (!string.IsNullOrEmpty(this.ReadOnlyText))
{
var lS = this.SelectionStart; var lL = this.SelectionLength;
this.Text = this.ReadOnlyText;
this.SelectionStart = lS; this.SelectionLength = lL;
}
}
void MyTextBox_MouseMove(object sender, MouseEventArgs e)
{
VisualStateManager.GoToState(this, "Normal", false);
}
void MyTextBox_MouseEnter(object sender, MouseEventArgs e)
{
VisualStateManager.GoToState(this, "Normal", false);
}
void MyTextBox_GotFocus(object sender, RoutedEventArgs e)
{
VisualStateManager.GoToState(this, "Normal", false);
}
}

不幸的是,您确实需要重新模板化。使用Blend会比手动编辑更容易。

只需将此样式应用于文本框即可。这是你能做到的唯一方法。

你看到的是Focus元素。它是文本框默认模板的一部分。制作自己的模板是控制元素风格的最佳方式。只需删除主要边框和焦点元素的边框,你就应该好好去。然后,您不再需要在XAML中设置内联边框粗细。
