I´ve tried to change the IsMouseOver & IsFocused BorderBrush of a TextBox.
But it seems not to take affect, I always get this ugly standart blue color.
My style is inside a ResourceDictionary.
It´s working perfectly fine, except the problem with changing the BorderBrush.
<Style x:Key="TextBoxA" TargetType="TextBox" >
<Setter Property="Foreground" Value="#FFF0E6D2"/>
<Setter Property="FontSize" Value="15" />
<Setter Property="BorderBrush" Value="#FF785A28"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Background" Value="#FF000306"/>

You need to modify the ControlTemplate. Right-click on the TextBox in design mode in Visual Studio and choose Edit Template->Edit a Copy to copy the default template into your XAML markup and then edit it as per your requirements:

Unless you edit the template of the control, you are pretty limited in what you can change. Here is the default template for the WPF TextBox, so change it to fit your desired style: https://learn.microsoft.com/en-us/dotnet/framework/wpf/controls/textbox-styles-and-templates
Having trouble figuring how out to have the text change styles when the text is changed. I have it set up so the styles change when I am typing and the default is set to be grayed out to indicate what needs to go in that field. I want the text to be black and of normal font weight when it is changed from the default text and to remain that way.
Here are my current trigger styles
<Style TargetType="{x:Type TextBox}">
<Setter Property="Foreground" Value="DimGray" />
<Setter Property="FontSize" Value="15" />
<Setter Property="FontStyle" Value="Italic" />
<Setter Property="Padding" Value="5,4,0,4" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBoxBase}">
<Border
x:Name="Bd"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
CornerRadius="7"
>
<Border.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="2,1">
<GradientStop Color="{Binding Path=GradientColorStart}" Offset="0"/>
<GradientStop Color="{Binding Path=GradientColorEnd}" Offset="1"/>
<!--
<GradientStop Color="#CCCCCC" Offset="0"/>

</Style>
This is something i would approach with the TargetNullValue of bindings, the string has to be null at first of course, so this might not be an option for you:
<TextBox Text="{Binding TestString, TargetNullValue=Enter Text Here, UpdateSourceTrigger=PropertyChanged}">
<TextBox.Style>
<Style TargetType="{x:Type TextBox}">
<Style.Triggers>
<DataTrigger Binding="{Binding TestString}" Value="{x:Null}">
<Setter Property="Foreground" Value="{StaticResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
Update: using Expression Blend 3
I'm trying to style the IsPressed & IsEnabled(false) property triggers for a class of buttons in a WPF application.
Here's a UserControl with a Button using the style...
<UserControl

<Button HorizontalAlignment="Left" Style="{DynamicResource BlueButton}" VerticalAlignment="Top" Width="155" Content="Button" Height="52.9"/>
</Grid>

And here's the style fragment...

<!-- fragment end -->
The Default and Mouse over changes work fine, but isEnabled false and isPressed true still show the Button default colors.
What am I doing wrong?
I fixed it after studying the code at http://mark-dot-net.blogspot.com/2007/07/creating-custom-wpf-button-template-in.html...
This is what I ended up with, which works great.

You need to replace the ControlTemplate to change the background color of your button.
Here is one I copied from MSDN that works well with your code.
You can merge your specific overrides to this style.
EDIT:
To make the following style work, as is, you need to download the Styling with Control Templates Sample from Microsoft. If you include Button.xaml and Shared.xaml from the sample the following style should work because these two files contain all the StaticResoruces listed the XAML below. I am testing in Visual Studio 2008.
Here is how I chanaged the user conttrol:
<UserControl x:Class="ButtonPressed.Views.KioskButton"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d"
Height="300" Width="300">
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary

</ResourceDictionary>
</UserControl.Resources>
<Grid>
<Button HorizontalAlignment="Left" VerticalAlignment="Top" Width="155" Content="Button" Height="52.9"/>
</Grid>
</UserControl>
Here is part of the button style from Button.xaml:

I have a controltemplate for buttons. I want to make the buttons with rounded corners. How should I do this?
I tried CornerRadius for button in the Border but it doesn't work. The background of the button has set to an image that has corner borders and the button looks akward as I can't set the corners for the button.
Try the following:
<Style x:Key="GlassButton" TargetType="{x:Type Button}">
<Setter Property="FontSize" Value="42" />
<Setter Property="Foreground" Value="White" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">

BorderThickness="4"
Background="#AA000000"
BorderBrush="Red"
RenderTransformOrigin="0.5,0.5">
<ContentPresenter x:Name="ButtonContentPresenter"
VerticalAlignment="Center"
HorizontalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="BorderBrush" Value="#FF4788c8" />

Is there a simple way to set the background brush of all inactive tabs in a WPF TabControl? I want to emulate the look of VS 2010 on a TabControl--the background color of the control's inactive tabs should match the background color of the window in which the TabControl is sited, so that you see only the text of the tab, and not the tab itself.
I know it will take a ControlTemplate to do it; I am trying to figure out what to put in the control template. Put another way, How do I specify that a particular brush should be applied to all inactive tabs? Thanks for your help.
Here is the solution: As Stephen said, add a trigger to the control template. It's actually a property trigger, and it only needs to be set for the inactive state. So we set the trigger for IsSelected = false. We target the border (Bd in the default control template for a TabItem) of the TabItem and set its Background to the color we want (I use RelativeSource FindAncestor to match the grid on which the tab is placed). Then we set Bd's BorderThickness to 0, and we're done:
<Trigger Property="IsSelected" Value="false">
<Setter Property="Background" TargetName="Bd" Value="{Binding Path=Background, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Grid}}}"/>
<Setter Property="BorderThickness" TargetName="Bd" Value="0" />
</Trigger>
I put the trigger in the default template, just below the IsSelected = true trigger.
Note that the trigger is hard-coded to search for a Grid ancestor as the source of the inactive tab background color (AncestorType={x:Type Grid}). That's because I set my view background in the Grid that I use as my layout root. You will need to change the AncestorType if you use a different layout root control, or if you set your view background color elsewhere (such as in the <Window> tag).
BTW, you can also use the IsSelected = true trigger to change the Background of the active tab header from white, to match the TabControl background color:
<Trigger Property="IsSelected" Value="true">
<Setter Property="Panel.ZIndex" Value="1"/>
<Setter Property="Background" TargetName="Bd" Value="{Binding Path=Background, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type TabControl}}}"/>
</Trigger>
For those who like this visual representation, here is the complete control template. It will be applied automatically to any TabControl within its scope. Simply add this markup to the section of your XAML window (or import it from a ResourceDictionary), and your TabControl will get the VS 2010 look. Remember to change the FindAncestor proeprty so that the template will find the correct background color.

Yes. Define the brushes, and then in your style for the tab, have a trigger for its active state, and when it is ACTIVE set it to one brush, and when the trigger fires because it is inactive set it to the other.
This can be done entirely in the XAML.
