选择 WPF 文本框边框时?
问题描述：
我想让 WPF 文本框具有深蓝色边框和等于 1 的厚度.即使选择了文本框，我也想让 WPF 具有此边框(深蓝色，厚度设置为 1).
I want to make a WPF TextBox have a DarkBlue border and thickness equal to 1. I want to make the WPF have this border ( DarkBlue, thickness set to 1 ) even when the TextBox is selected.
我尝试通过以下代码完成此任务.但是，它根本不起作用.任何想法或提示?任何帮助将不胜感激.
I tried doing this task by the following code. However, it doesn't work at all. Any ideas or hints ? Any help would be greatly appreciated.
<Style x:Key="ReadOnlyLargeTextBox" TargetType="{x:Type TextBox}" >
<Setter Property="Height" Value="80"/>
<Setter Property="MaxHeight" Value="80"/>
<Setter Property="VerticalScrollBarVisibility" Value="Visible"/>
<Style.Triggers>
<Trigger Property="TextBox.IsMouseOver" Value="True">
<Setter Property="BorderBrush" Value="DarkBlue"/>
<Setter Property="BorderThickness" Value="1"/>
</Trigger>
<Trigger Property="TextBox.IsMouseOver" Value="False">
<Setter Property="BorderBrush" Value="DarkBlue"/>
<Setter Property="BorderThickness" Value="1"/>
</Trigger>
</Style.Triggers>
</Style>
P.S 请注意，文本框没有 IsSelected 属性.
P.S Note that the text box does not have an IsSelected property.
