This is a part of my App.xaml code.
It is style for textBox.
But Background Property didn't work.
Others work well.
Please help me. Why can't I change background color of TextBox?


You are giving a background to your text box, instead you should give the background to your border because it has been defined in the control template.
<Style x:Key="TextInputStyle" TargetType="TextBox" BasedOn="{StaticResource {x:Type TextBox}}">
<Setter Property="FontSize" Value="12"/>
<Setter Property="Margin" Value="5,5,5,5"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Setter Property="Foreground" Value="AliceBlue"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border x:Name="bg" BorderBrush="#FF7F98DC" BorderThickness="1" ***Background="Red"***>
<ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" TargetName="bg" Value="#FF7E97F0"/>
<Setter Property="BorderThickness" TargetName="bg" Value="2"/>
</Trigger>
<Trigger Property="IsFocused" Value="True">
<Setter Property="BorderBrush" TargetName="bg" Value="DarkBlue"/>
<Setter Property="BorderThickness" TargetName="bg" Value="2"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>

Please see the Border tag inside ControlTemplate above.

Why PasswordBox is not getting a rounded corner style?

I wrote a style code for TextBox rounded corner and it worked. But When I tried the same code just changing the TargetType field to PasswordBox It didn't work for PasswordBox.
Thanks in advance.
This is my style code:
<Style x:Key="TextBoxTemplate" TargetType="TextBox">
<Setter Property="Background" Value="#525252"/>
<Setter Property="Foreground" Value="White"/>
<Setter Property="BorderThickness" Value="0,0,0,1"/>
<Style.Resources>
<Style TargetType="Border">
<Setter Property="CornerRadius" Value="10"/>
</Style>
</Style.Resources>
</Style>
<Style x:Key="PasswordBoxTemplate" TargetType="PasswordBox">
<Setter Property="Background" Value="#525252"/>
<Setter Property="Foreground" Value="White"/>
<Setter Property="BorderThickness" Value="0,0,0,1"/>
<Style.Resources>
<Style TargetType="Border">
<Setter Property="CornerRadius" Value="10"/>
</Style>
</Style.Resources>
</Style>
This is my XAML style binding code:
<PasswordBox Style="{DynamicResource PasswordBoxTemplate}" Name="txtPassword" FontSize="18"/>

The PasswordBox is special in that it resets the Border style. It is implemented this way. What you can do is you can copy the default style of the PasswordBox and adapt the corner radius directly.
<Style x:Key="PasswordBoxStyle" TargetType="{x:Type PasswordBox}">
<Setter Property="PasswordChar" Value="●"/>
<Setter Property="Background" Value="#525252"/>

AdornedElementPlaceholder not working: validation borders disappear on changing the tab

I have various text boxes in my application, where i have used a red border to validate the data being entered. the problem is when i change tabs the red border disappears. So i am trying to apply AdornedElementPlaceholder in my styles file so that all the textboxes can adapt that behaviour. I have tried the below mentioned code but the line of code in bold (AdornedElementPlaceholder) is not working. I am using WPF and C#. Can anyone please help?

Disable Button but keep the color of the background

i have the following button style which works fine:
<Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border x:Name="Border"
CornerRadius="2" BorderThickness="1"
Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}">
<ContentPresenter Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Border" Property="Background" Value="{StaticResource DisabledBackgroundBrush}" />
<Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DisabledBorderBrush}" />
<Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
with more styles defined at the button itself i change the buttons background (green for active)
<Button>
<Button.Style>
<Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
<Style.Triggers>
<DataTrigger Binding="{Binding MainStatus.Restart}" Value="true">
<Setter Property="Background" Value="LimeGreen" />
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
now if i disable the button, the button gets gray, because of the template. is there a way of making the current background more 'gray' but keeping the base color. so if the button was green, the color remains basically green?

Instead of setting background gray, you can set opacity to give it a disabled look (this will retain your background) something like this:
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<!--<Setter TargetName="Border" Property="Background"
Value="{StaticResource DisabledBackgroundBrush}" />-->
<Setter TargetName="Border" Property="Opacity" Value="0.4"/>
<Setter TargetName="Border" Property="BorderBrush"
Value="{StaticResource DisabledBorderBrush}" />
<Setter Property="Foreground"
Value="{StaticResource DisabledForegroundBrush}"/>
</Trigger>
</ControlTemplate.Triggers>

Create style:
<Style.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="#FFADADAD"/>
</Trigger>
</Style.Triggers>

WPF TextBox border on Windows7

In Windows7 (maybe vista too), TextBoxes now get a blue emphasis rect when they receive input focus or get the MouseOver.
In my WPF app, that blue focus rect really sticks out like a sore thumb - it does NOT match the visual style of the rest of the app.
How do I disable it - or better yet, customise it?
(Setting FocusVisualStyle to {x:Null} in the xaml does nothing.)

This is because of the default style applied for the TextBox. To modify this behavior you have to create a custom style/template. just have a look at this sample
<Style x:Key="TextBoxStyle1" BasedOn="{x:Null}" TargetType="{x:Type TextBox}">
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="AllowDrop" Value="true"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="ScrollViewer.PanningMode" Value="VerticalFirst"/>
<Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border x:Name="border" Background="#FF8F8F8F" BorderBrush="#FF585858" CornerRadius="3" BorderThickness="2">
<ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="BorderBrush" TargetName="border" Value="Silver"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" TargetName="border" Value="0.15"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" TargetName="border" Value="Silver"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

How to I stop Vista from pulsating my focused XAML buttons?

I've created a style for buttons in my WPF application.
However, on Vista, when a button is focused, it pulsates with a light blue that doesn't look good in the design.
How can I override this automatic pulsating?
<Style x:Key="NavigationButtonStyle" TargetType="Button">
<Setter Property="Width" Value="400"/>
<Setter Property="Height" Value="100"/>
<Setter Property="Cursor" Value="Hand"/>
<Setter Property="FontSize" Value="56"/>
<Setter Property="Foreground" Value="#aaa"/>
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="#ddd" />
</Trigger>
<Trigger Property="IsEnabled" Value="True">
<Setter Property="Foreground" Value="#aaa" />
</Trigger>
</Style.Triggers>
</Style>
Tried "IsFocused":
Adding this doesn't have any effect on Vista, the button still looks the same and is pulsating in Vista when focused:
<Trigger Property="IsFocused" Value="True">
<Setter Property="Background" Value="Red" />
<Setter Property="Foreground" Value="Blue" />
</Trigger>
Tried "ControlTemplate" solution:
Still no effect:
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle SnapsToDevicePixels="true" Margin="2" Stroke="Black" StrokeDashArray="1 2" StrokeThickness="1"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="NavigationButtonStyle" TargetType="Button">
<Setter Property="Width" Value="400"/>
<Setter Property="Height" Value="100"/>
<Setter Property="Cursor" Value="Hand"/>
<Setter Property="FontSize" Value="56"/>
<Setter Property="Foreground" Value="#aaa"/>
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="#ddd" />
</Trigger>
<Trigger Property="IsEnabled" Value="True">
<Setter Property="Foreground" Value="#aaa" />
</Trigger>
</Style.Triggers>
</Style>

This effect is being set in response IsKeyboardFocused, not just standard focus.
In Blend if you edit the control template for a standard button, you'll see that on the IsKeyboardFocused=true trigger is responsible for this effect.
<Style x:Key="Button_NonGlow" TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
<Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/>
<Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Microsoft_Windows_Themes:ButtonChrome SnapsToDevicePixels="true" x:Name="Chrome" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" RenderDefaulted="{TemplateBinding IsDefaulted}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}">
<ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/>
</Microsoft_Windows_Themes:ButtonChrome>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter Property="RenderDefaulted" TargetName="Chrome" Value="true"/>
</Trigger>
<Trigger Property="ToggleButton.IsChecked" Value="true">
<Setter Property="RenderPressed" TargetName="Chrome" Value="true"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="#ADADAD"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

What you are looking for is the IsFocused trigger property. Sorry that I do not have a working example for you right here.
UPDATE:
I found this small piece of code that I once used. I am not sure if is works and I can not test it (I am on an XP box):
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle SnapsToDevicePixels="true" Margin="2" Stroke="Black" StrokeDashArray="1 2" StrokeThickness="1"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
</Style>

Depending on your specific requirements you can simply ensure the button never gets keyboard focus by setting IsTabStop="False" and IsDefault="False".
