在Silverlight中，我如何与的IsReadOnly =文本框真不会成为灰色显示。灰色效果看起来可怕与我的应用程序，我想禁用它，或者改变其外观/颜色。

In Silverlight, How do I make a TextBox with IsReadOnly="True" not become grayed out. The gray effect looks horrible with my app and I would like to disable it, or change its appearance/color.

推荐答案

有在Silverlight 2几个选项，最简单的是使用一个TextBlock因为这永远只能是只读的。

There are a couple of options in Silverlight 2, the simplest would be to use a TextBlock since that's only ever readonly.

如果你需要一个文本框，然后你需要做的是给它一个不同的风格，没有做灰色的影响。

If you need a TextBox then what you need to do is give it a different style that doesn't do the grey affect.

要做到这一点打开了融合。右键点击你的文本框，然后选择编辑控件部件（模板） - >编辑复制...叫你想做新的样式

To do this open up blend. right click on your TextBox and select Edit Control Parts (Template) -> Edit a Copy... Call the new style whatever you want.

您再要编辑这个新的风格和删除名为ReadOnlyVisualElement的边界，并删除它改变了边框的不透明性的故事情节。

You then want to edit this new style and delete the border called "ReadOnlyVisualElement" and delete the storyboard that alters the opacity property of that border.

希望这有助于。

增加XAML样式

    <Style x:Key="ReadOnlyStyle" TargetType="TextBox">
		<Setter Property="BorderThickness" Value="1"/>

我会得到融合的preVIEW，编码上面用手工将大量的不必要的工作。

I would get the preview of Blend, coding the above by hand would be a large amount of unnecessary work.
