How to remove border from Textbox in WPF?
提问by F????? A???
These borders appear when they are clicked or hovered and don't go until the focus is lost. There are borders on all four sides but since it is embedded in a shorter grid, the top and bottom ones are not visible. How to remove these borders? Please provide an example if possible.
这些边框在被点击或悬停时出现，直到失去焦点才会消失。所有四个边都有边框，但由于它嵌入在较短的网格中，顶部和底部的不可见。如何去除这些边框？如果可能，请提供一个例子。

you can remove the border by just setting the BorderBrush property to Transparent.
您只需将 BorderBrush 属性设置为 Transparent 即可移除边框。

Normal View:Set the BorderBrush property to "Transparent"
普通视图：将 BorderBrush 属性设置为“透明”
<Button Name="BtnTest"
Content="Test"
BorderBrush="Transparent"
Height="20"
Width="75"/>
Hovering View:While you are hovering the control with mouse, Include these Control Template for Button or any control like Textbox or Textblock etc.. under the Window.Resources Tag
悬停视图：当您用鼠标悬停控件时，在 Window.Resources 标签下包含按钮或任何控件（如文本框或文本块等）的这些控件模板
<Window.Resources>
<Style TargetType="Button">
<!--Default Values-->
<Setter Property="BorderBrush"
Value="Transparent"/>
<!--Transparent Highlight-->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
