I have a UserControl which contains a Button, this Button then contains an Image and a TextBlock. This enabled me to have an image button. I also want the button to have a borderless style, which I have achieved by setting the button BorderBrush to null. This part all works fine.
The problem I have is when I want to "disable" the UserControl. I can do this by settings the IsEnabled property to false, which cascades down to the button and appropriately prevents the button from being clicked. However, when the button is disabled it displays a border, which I do not want.
Question: How can I get rid of the button's border when it is disabled?
I have tried a few different methods such as setting the border from code:
MyButton.BorderBrush = Brushes.Transparent;
and using a style in the XAML:
<Button.Style>
<Style TargetType="Button">
<Setter Property="BorderBrush" Value="{x:Null}"/>
</Style>
</Button.Style>
and a few other things just to try and get something to work, but nothing has made any difference so far.
NOTE: I have tried both above solutions with the Opacity property and both work fine in that respect, but not when I try to change the border
Unfortunately, the Style that is applied to the Button when it is disabled is applied in the default ControlTemplate. That means that if you want to change it, you'll need to define a new ControlTemplate for your Button. You can find the default ControlTemplate in the Button Styles and Templates page on MSDN.
When providing a new ControlTemplate, one sometimes misses parts from the original template, so a good starting point is to implement the default ControlTemplate as it is on that page and then 'tweak' it to your liking.
Since you already have a template for your Button you'll need to insert a Trigger with the Property="IsEnabled" Value="False":
A sample ControlTemplate for a Button:
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" TextBlock.Foreground="{StaticResource Button.Static.Foreground}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
<Setter Property="TextBlock.Foreground" TargetName="border" Value="{StaticResource Button.MouseOver.Foreground}" />
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>
<Setter Property="TextBlock.Foreground" TargetName="border" Value="{StaticResource Button.Pressed.Foreground}" />
</Trigger>
//Here's the code where you want to change the border
//Change the Value part to whatever you want.
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Sorry about the indentation, but I believe you'll achieve what you want!

Whats wrong with this trigger? I found it here: http://www.wpf-tutorial.com/styles/trigger-datatrigger-event-trigger/ and ive seen similar setups on SO
<Button x:Name="ColorPickerButton" Background="{Binding SelectedColor}">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
Im trying to break down my spaghetti XAML and make it more readable. This is my old implementation which does work. I dont like it because it overwrites the button content and overlays a border which seems unnecessary. Also its massive
<Button x:Name="ColorPickerButton" Background="{Binding SelectedColor}">
<Button.Resources>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Bd"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"
Padding="{TemplateBinding Padding}"
SnapsToDevicePixels="true">
<GridViewRowPresenter/>
</Border>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsMouseOver" Value="True"/>
</MultiTrigger.Conditions>
<Setter Property="BorderBrush" Value="{StaticResource ColorPickerButton.MouseOver.Border}"/>
</MultiTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Resources>
</Button>
Your Trigger does not work because the default Template of the button has its own trigger that changes the background brush of the root border when the IsMouseOver Property is set. This means: As long as the mouse is on top of the button, the Background-property of the button control will be ignored by its template.
The easiest way to check out the default style of your button is to: right-click at the button in the visual studio wpf designer. Click 'Edit template' -> 'Edit a copy' and select a location.
A copy of the default style is created at the specified location. You will see a trigger like this:
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
</Trigger>
On top of designer created style definition it also created the brushes that are used within the style:
<SolidColorBrush x:Key="Button.MouseOver.Background" Color="#FFBEE6FD"/>
<SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/>
You can either change these brushes or the Value property of the setters above to change the background when the mouse is over.
Or you create your own Template like you did in your old implementation.
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

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 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.
I require a toggle button that has not border when IsChecked = False and has a simple 1pt border of a certain color when IsChecked = True. I have the following style but my border when the button IsChecked = True is being set to Transparent (using Snoop to inspect)
<Style x:Key="InfoToggleButton"
TargetType="{x:Type ToggleButton}">
<Setter Property="Background" Value="#EEEEF2"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Border CornerRadius="0"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<ContentPresenter x:Name="contentPresenter"
ContentTemplate="{TemplateBinding ContentTemplate}"
Content="{TemplateBinding Content}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="BorderBrush" Value="#007ACC"/>
<Setter Property="BorderThickness" Value="1"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="0"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
The button works and displays properly, but when I check/click it, the border does not get displayed.
I implement this style like
<ToggleButton Grid.Column="0"
Style="{StaticResource InfoToggleButton}"
IsChecked="{Binding IsDisplayingBetInfo, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Content="{Binding BetInfoIconSource}"/>
How can I get a simple toggle button with border?
Thanks for your time.
I've figured out the problem and the solution but don't exactly know why it happens.
Problem: Some value other than {x:Null} must be set as the content of the toggle button.
Solution: However, a blank string can be set as the content.
My reasoning: When no content is set, the ContentPresenter is null and thus cannot be clicked.
The problem can be solved by setting the default content to "" like this:
<Style x:Key="InfoToggleButton"
TargetType="{x:Type ToggleButton}">
<Setter Property="Background" Value="#EEEEF2"/>
<Setter Property="Content" Value=""/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Border CornerRadius="0"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<ContentPresenter x:Name="contentPresenter"
ContentTemplate="{TemplateBinding ContentTemplate}"
Content="{TemplateBinding Content}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="BorderBrush" Value="#007ACC"/>
<Setter Property="BorderThickness" Value="1"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="0"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
you have to assign a name at the Border tag like in this way
<Border x:Name="MyBorderName"...
then the you have to assign the TargetName at the property.
Example
<Setter TargetName="MyBorderName" Property="BorderBrush" Value="#007ACC"/>
<Setter TargetName="MyBorderName" Property="BorderThickness" Value="1"/>
Otherwise WPF does not know who to assign the Property BorderBrush and BorderThickness
I am making a WPF project. While running the application, as I take my cursor to a button, it gets highlighted by blue color filled inside it.
Now, I want to remove this highlight...
How do I do so?
The link isn't working for me, so I can't see exactly what you are getting at, but I assume that you're trying to change that default blue-ish gradient. You need to override the template for the button in a style, and then you can customize it to look however you want. You can't just set the background color or use triggers to change it without overriding the template, because the default template has some extra stuff in it to show that gradient effect.
Here is an example of a button I have used before that is fairly straightforward. This example uses a trigger to change the foreground color of the button when it is pressed, but will never change the background color.
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="White"/>
<Setter Property="FontWeight" Value="SemiBold"/>
<Setter Property="Foreground" Value="{StaticResource BrushBtnText}"/>
<Setter Property="Margin" Value="8,4,8,4"/>
<Setter Property="Padding" Value="6"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="BorderBrush" Value="{StaticResource BrushBorderLight}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Margin="{TemplateBinding Margin}"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Padding="{TemplateBinding Padding}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Foreground" Value="{StaticResource BrushBtnText}"/>
</Trigger>
</Style.Triggers>
</Style>
Also, if you're interested, here is what the button's default template is:
<Style 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}">
<Themes:ButtonChrome x:Name="Chrome" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}" RenderDefaulted="{TemplateBinding IsDefaulted}" SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</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>
Actually, I found the thing where I was going wrong. Whenever my pointer goes to a button, does not change the background of the button or even the foreground of the button, but it changes the background of the border.
So, while overwriting the button style, actually the border of the background has to be overwritten and not the button foreground or the background.
