wpf textbox flat border style

The way to do this is to use a control template to draw the border yourself. You can do this in many different ways, heres a couple for you to look at.
The quick hack approach:
<TextBox>
<TextBox.Template>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<Rectangle Stroke="{StaticResource ResourceKey=detailMarkBrush}" StrokeThickness="1"/>
<TextBox Margin="1" Text="{TemplateBinding Text}" BorderThickness="0"/>
</Grid>
</ControlTemplate>
</TextBox.Template>
</TextBox>
and then theres using resources...
<ResourceDictionary>
<Color x:Key="detailMark">#FFA1A9B3</Color>
<SolidColorBrush x:Key="detailMarkBrush" Color="{StaticResource ResourceKey=detailMark}" />
<Style x:Key="flatTextBox" TargetType="{x:Type TextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<Rectangle Stroke="{StaticResource ResourceKey=detailMarkBrush}" StrokeThickness="1"/>
<TextBox Margin="1" Text="{TemplateBinding Text}" BorderThickness="0"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
and then you can use the style:
<TextBox Style="{StaticResource ResourceKey=flatTextBox}" />
Solution 2
<TextBox BorderThickness="1" BorderBrush="Black">
just try this by black or gray
Solution 3
This is better way to me, make a custom template with border, to override the default one.
And most important make ScrollViewer
named PART_ContentHost
, to fit inner TemplatePart
, and for any other features work like default.
simular to example from MSDN:
<Style TargetType="TextBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBoxBase}">
<Border CornerRadius="2" Padding="2" Background="#19212F" BorderBrush="Red" BorderThickness="1">
<ScrollViewer Margin="0" x:Name="PART_ContentHost" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Michael Shaw over 12 yearsThis only appears to work whilst the textbox is not focused. When it gets the focus, the border is highlighted with two blue shades.
