I am trying to set inactive buttons to have semi-transparent (i.e. greyed out) images. Yet for some reason the images become white/ yellow (as if on a bright background):
As you can see it's light yellow
Possibly better annotated screenshot
Here are the XAML Styles:
<Style x:Key="ToolButton" TargetType="{x:Type Button}" BasedOn="{x:Null}">
<Setter Property="Background" Value="#888"/>
<Setter Property="Padding" Value="10,2"/>
<Setter Property="BorderThickness" Value="0"/>
<Style.Resources>
<Style TargetType="Image">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" Value="0.5"/>
</Trigger>
</Style.Triggers>
</Style>
</Style.Resources>
</Style>
<Style x:Key="ToolPanel" TargetType="{x:Type StackPanel}">
<Setter Property="Background" Value="#111"/>
<Style.Resources>
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource ResourceKey=ToolButton}"/>
</Style.Resources>
</Style>
(StackPanel and buttons are dark for contrast, they are actually mean to be light grey)
What should I do to get the greyed out effect I want?
The problem is the default Button template: it changes its background based on the control's state, and that new background takes precedence over the one you're setting in your style.
In this case, the brush for the 'Disabled' state is something like #F4F4F4, or a very light gray.
The fix would be to declare a new Button template. For example:
<ControlTemplate TargetType="Button">
<!--Optional: Add border brush/thickness if you want a border-->
<Border x:Name="border" Background="{TemplateBinding Background}">
<ContentPresenter x:Name="contentSite" Margin="{TemplateBinding Padding}" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<!--Optional: Remove background when disabled-->
<!--Setter TargetName="border" Property="Background" Value="Transparent" /-->
<Setter TargetName="contentSite" Property="Opacity" Value="0.5" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="border" Property="Background" Value="#AAA" />
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="border" Property="Background" Value="#333" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Note that with this version, you do not need the Image style to change the Opacity; it's taken care of in the Button template.

I'm trying to recreate a Valve VGUI interface style in WPF. So far I am able to assign a border to a button, but the border style does not change when pressing the button.
Here's my XAML code:
<Window.Resources>
<Style x:Key="BorderLight_Style" TargetType="Border">
<Setter Property="BorderBrush" Value="#889180" />
<Setter Property="BorderThickness" Value="1,1,0,0" />
</Style>
<Style x:Key="BorderShadow_Style" TargetType="Border">
<Setter Property="BorderBrush" Value="#FF282E22" />
<Setter Property="BorderThickness" Value="0,0,1,1" />
</Style>
<Style x:Key="BorderLight_Style_pressed" TargetType="Border">
<Setter Property="BorderBrush" Value="#FF282E22" />
<Setter Property="BorderThickness" Value="1,1,0,0" />
</Style>
<Style x:Key="BorderShadow_Style_pressed" TargetType="Border">
<Setter Property="BorderBrush" Value="#889180" />
<Setter Property="BorderThickness" Value="0,0,1,1" />
</Style>
<Style TargetType="Grid">
<Setter Property="Background" Value="#FF4C5844" />
</Style>
<Style TargetType="Button">
<Setter Property="Background" Value="#FF4C5844" />
<Setter Property="Foreground" Value="#D8DED3" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border x:Name="border" Style="{StaticResource BorderShadow_Style}">
<Border x:Name="border2" Style="{StaticResource BorderLight_Style}" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="border" Property="Style" Value="{StaticResource BorderShadow_Style_pressed}" />
<Setter TargetName="border2" Property="Style" Value="{StaticResource BorderLight_Style_pressed}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
Am I doing anything wrong with this? Thanks!
Controls need to have a defined Background property to participate in hit-testing - and thus to allow the IsPressed property to be set on a Button for example.
Set the Background property of your inner Border to any valid value - such as Transparent - to fix your Trigger.
Note: if you were to press TAB to select your button and press the space bar, you would see your Trigger working even though you didn't set it any background, because IsPressed also reacts to the space bar.
I have a HomePage with a number of buttons on that I am trying to get to do a couple of things. Firstly, I have a Style in a ResourceDictionary that dictates the overall 'look and feel' of the buttons. It looks like this:
<Style TargetType="Button" x:Key="HomeButton">
<Setter Property="Foreground" Value="White"/>
<Setter Property="Background" Value="#06658D"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}" BorderBrush="White" BorderThickness="1">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Background" Value="White"/>
<Setter Property="Foreground" Value="#06658D"/>
</Trigger>
</Style.Triggers>
</Style>
Nothing too complicated, however I want the MouseOver effect to persist after being clicked. So now I am looking at doing something like this:
<Button Grid.Row="0" Style="{StaticResource HomeButton}" Content="Contacts">
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<DataTrigger Binding="{Binding ContactsClicked}" Value="True">
<Setter Property="Background" Value="White"/>
<Setter Property="Foreground" Value="#06658D"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Button>
I'll bind the command element of the Button to set ContactsClicked = true and reset this when another button is pressed. However, I get the error saying that Content is set multiple times.
Is it possible to have an overall Style of the Button set, as well as a 'Clickedstyle and to have aTextBlockdisplaying text on the button all at once or am I approaching this wrong? I am trying to not have an individual overall style for every singleButton`as that's a lot of repeated code.
For clarity this is what I am aiming for:
I've managed to find a solution myself, instead of using a Button us a ToggleButton instead:
<Style TargetType="ToggleButton" x:Key="HomeButton">
<Setter Property="Foreground" Value="White"/>
<Setter Property="Background" Value="#06658D"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Border Background="{TemplateBinding Background}" BorderBrush="White" BorderThickness="1">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="Black" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Background" Value="White"/>
<Setter Property="Foreground" Value="#06658D"/>
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Background" Value="White"/>
<Setter Property="Foreground" Value="#06658D"/>
</Trigger>
</Style.Triggers>
</Style>
I would add this as a comment but im not allowed.
If your goal is that the button will stay selected after it is clicked, why not use a RadioButton? A RadioButton has a built-in property called IsChecked but will also remain "Checked" or "Selected" even after multiple clicks.
Of course you can define the behavior and the styles in a similar manner, create a simple Trigger on the property IsChecked.
If more explanation is needed, just say so.
When i add this controltemplate my checkboxes disapear and only the checkbox text is shown. And when mouse is over the textbackground becomes red, how do i get my checkbox background red when mouse is over?
<Style TargetType="CheckBox" x:Key="Checkbox">
<Setter Property="BorderThickness" Value="2" />
<Setter Property="VerticalAlignment" Value="Top" />
<Setter Property="Margin" Value="20,15,0,0" />
<Setter Property="FontFamily" Value="/Resources/Fonts/Source Sans Pro/#Source Sans Pro" />
<Setter Property="FontSize" Value="14" />
<Setter Property="HorizontalAlignment" Value="Left" />
<Setter Property="Foreground" Value="{DynamicResource CheckboxForegroundColor}" />
<Setter Property="Background" Value="{DynamicResource CheckboxBackgroundColor}" />
<Setter Property="BorderBrush" Value="{DynamicResource CheckboxBorderbrushColor}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<CheckBox Background="{TemplateBinding Background}" >
<ContentPresenter />
</CheckBox>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
This will work for some properties (try FontSize, for example), but not for others. The default template for the CheckBox has triggers of its own, and they don't bother with such things as TemplateBindings.
This post tells you how to extract the default template for a ComboBox. Here is an excerpt which shows your problem:
<ControlTemplate.Triggers>
...
<Trigger Property="IsMouseOver" Value="true">
<Setter
Property="Background"
TargetName="checkBoxBorder"
Value="{StaticResource OptionMark.MouseOver.Background}"/>
...
</Trigger>
...
</ControlTemplate.Triggers>
Your best bet is probably to override the entire template. Happily, it isn't too complex...
Remove your own template.
Follow the steps outlined in the post I linked to. That should give you a copy of the default CheckBox template.
Modify that copy. In particular, the IsMouseOver trigger that I excerpted: Change {StaticResource OptionMark.MouseOver.Background} to Red.
If this is still unclear, see this related post.
I have a Style-Template for my buttons in my app, that looks like this:
<Style TargetType="{x:Type Button}">
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Name="Border">
<ContentPresenter RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter TargetName="Border" Property="BorderBrush" Value="#ffffff" />
</Trigger>
<Trigger Property="IsDefaulted" Value="true">
<Setter TargetName="Border" Property="BorderBrush" Value="#ffffff" />
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border" Property="Background" Value="Transparent" />
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter TargetName="Border" Property="Background" Value="Transparent" />
<Setter TargetName="Border" Property="BorderBrush" Value="#ffffff" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Border" Property="Background" Value="Transparent" />
<Setter TargetName="Border" Property="BorderBrush" Value="#ffffff" />
<Setter Property="Foreground" Value="Transparent"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Now I wanted to put a MouseEnter and a MouseLeave Event in some of my buttons and change their background, etc. on the fly. If I disable the Style, everything works fine as expected (except, that the buttons get the border and the blue background of the standard style).Now my question would be: "How can I change the style to a borderless, transparent button without blue background on MouseOver and get the MouseEnter and MouseLeave to fire, so I can set the background programmatically?
you should add extra styles for the buttons that you want to react differently than the rest, then use the triggers like in your pasted code to change backgrounds.
<Style x:Key="diffrentButton" TargetType="{x:Type Button}">
...
I have a global style for all my textboxes like so:
<Style TargetType="TextBox">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" Value="Red"/>
</Trigger>
</Style.Triggers>
<Setter Property="BorderBrush" Value="#007acc"/>
<Setter Property="Foreground" Value="GhostWhite"/>
<Setter Property="Background" Value="#49494e"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="Width" Value="250"/>
<Setter Property="Margin" Value="0,0,0,5"/>
</Style>
When I hover over a textbox with a mouse, its border color will correctly snap to a red color for couple of instants but then the default animation takes over and changes it into the default textbox bluish border color.
How can I disable, or overwrite this animation without having to redefine the entire textbox template? I just want the border color to stay red, while the mouse cursor is hovering over the textbox.
One solution to your problem would be to change Template of TextBox
<Style TargetType="{x:Type TextBox}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" Value="Red"/>
</Trigger>
</Style.Triggers>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="1">
<ScrollViewer x:Name="PART_ContentHost"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="BorderBrush" Value="#007acc"/>
<Setter Property="Foreground" Value="GhostWhite"/>
<Setter Property="Background" Value="#49494e"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="Width" Value="250"/>
<Setter Property="Margin" Value="0,0,0,5"/>
</Style>
This is actually a known issue with property precedence. Basically your local property setter for the border brush is clashing with your trigger. This Msdn article explains it more fully but essentially if you remove
<Setter Property="BorderBrush" Value="#007acc"/>
your trigger should work correctly
