Button Change Background Color on Click / Press - c#

I have what I thought would be an easy issue to resolve but for the life of me I cant get exactly what i want using WPF (coming from a WinForms background).
All I am trying to do is create a button which the background color changes just while the button is pressed / clicked. Once the button is released, it reverts back to normal. Based on this I am trying to also have nothing happen on Mouse Hover.
Ive managed to create a template to remove the Mouse Over effects but can seem to figure out how to change the background color just whilst clicked / pressed and then reset.
I have been working off this template from another Stack Over flow post which gives me a nice transition of the button being pressed.
I am happy to lose the effect but was using this as a basis for trying to understand how to piece it all together.

The answer is actually pretty simple - you already have a "Is Pressed" trigger - you just need to add a background setter there, for example:
<Setter Property="Background" Value="Red"/>
To make it simple to understand, we can see a simplified version of your template:
<Style x:Key="InformButton" TargetType="{x:Type Button}">
<Setter Property="Background" Value="LightBlue">
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" BorderThickness="1" Padding="4,2"
BorderBrush="DarkGray" CornerRadius="3"
Background="{TemplateBinding Background}">
<Grid>
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center" x:Name="content" />
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Here you can see that all we have is a basic background (Light blue), a content presenter for the content and a trigger that if the button is pressed, will change the color to red.
Personally, I think that this minimal template also looks better as it will match the global font settings and style.

how to create the blue border on checkbox when mouse is over the containing element C# WPF

I have a WrapPanel containing a Label and a CheckBox. The idea is to make the Label and the CheckBox look like 1 element, so when the WrapPanel's MouseLeftButtonUp is fired (weather the event happens on the CheckBox, or the Label), the checkbox inside it becomes checked (or unchecked if it was already checked).
In WPF, when you move your mouse over a CheckBox it gets this blue border. i want it to happen when the mouse goes over any part of the WrapPanel (the Label or the CheckBox itself)
I tried to call the myCheckbox.Focus(); when the MouseEnter for the WrapPanel is fired, but didn't do the trick.
I also saw this link on how to make checkbox focus border apear when calling CheckBox.Focus(), but it didn't answer my question either.
Any help is appreciated.
Modify the template of the CheckBox to use a WrapPanel instead of the default Grid:
<CheckBox>
<TextBlock>Label that wraps with the CheckBox...</TextBlock>
<CheckBox.Style>
<Style TargetType="{x:Type CheckBox}">

If you're open to an alternative (simpler) solution, This is how you should do it: define a custom style for the checkbox and override the Template so to get the WrapPanel and whatever controls you want look as part of the CheckBox..
<Style TargetType="{x:Type CheckBox}" x:Key="myCheckboxStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<WrapPanel>
<Label />
<!-- other Controls -->
<ContentPresenter/>
</WrapPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Apply the custom style to the checkbox
<CheckBox Style="{StaticResource myCheckboxStyle}" Content="Check Me"/>

How to disable a button and change it's color?

I have this code I found on here, that generates me a grid of buttons - I know this may not be the best way to do this, but for now I'd like to do it this way, I am quite new at this. So the button should be either Black(1) or White(0), depending on it's value. This all works, until I hover the button and I can see it's value. If I just add the Visibility property = "false" to the button, it does not even get displayed.
This is my code:
<Window.Resources>
<DataTemplate x:Key="DataTemplate_Level2">
<Button Content="{Binding}" Height="15" Width="15" Margin="1,1,1,1">
<Button.Style>
<Style TargetType="Button">
<Style.Triggers>
<DataTrigger Binding="{Binding}" Value="1">
<Setter Property="Background" Value="Black"/>
<Setter Property="Foreground" Value="Black" />
</DataTrigger>
<DataTrigger Binding="{Binding}" Value="0">
<Setter Property="Background" Value="White"/>
<Setter Property="Foreground" Value="White" />
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
</DataTemplate>
<DataTemplate x:Key="DataTemplate_Level1">
<ItemsControl ItemsSource="{Binding}" ItemTemplate="{DynamicResource DataTemplate_Level2}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</DataTemplate>
</Window.Resources>
And then I display the grid here:
<Grid Margin="10,10,10,-636" Grid.Row="3">
<ItemsControl x:Name="automata" ItemTemplate="{DynamicResource DataTemplate_Level1}" Margin="0,0,0,-119"/>
</Grid>
I would also be happy of a recommendation on how to display these values in another way.
If you want to change the appearance or visual states of a control, create a style with a ControlTemplate that fits your requirements. You can also extract the default style using Blen or Visual Studio and adapt it.
In the following, I took the default style with its control template for Button and commented out the triggers for MouseOver, Pressed and other states so they are ineffective, but you still see where to continue since your question certainly is only the starting point for further customization. I adapted and added your triggers to the ControlTemplate. What this does is simply show a black button for 1 and white for 0.
<Style x:Key="MyButtonStyle" TargetType="{x:Type Button}">

</Trigger>-->
<!-- These are your triggers, which now act on the Content property of the templated button. -->
<DataTrigger Binding="{Binding Content, RelativeSource={RelativeSource TemplatedParent}}" Value="1">

<Setter Property="Foreground" Value="Black" />
</DataTrigger>

<Setter Property="Foreground" Value="White" />
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Use this style in your data template and you should get the expected result.
<DataTemplate x:Key="DataTemplate_Level2">
<Button Content="{Binding}" Height="15" Width="15" Margin="1,1,1,1" Style="{DynamicResource MyButtonStyle}"/>
</DataTemplate>
Since you try to make the text 1 and 0 invisible by setting the background and foreground to the same color, you could also simply remove the ContentPresenter from the ControlTemplate, so there is no content displayed at all and the Foreground setters are not needed.
Another thing to note is that your binary state maybe suggests to use a ToggleButton instead.
Base class for controls that can switch states, such as CheckBox.
This is an example style for a ToggleButton that does not show content and sets the background like in your question, but dependening on its IsChecked property.
<Style x:Key="MyToggleButtonStyle" TargetType="{x:Type ToggleButton}">
<Style.Resources>
<SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/>
<SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/>
</Style.Resources>
<Setter Property="FocusVisualStyle">
<Setter.Value>
<Style>
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" StrokeDashArray="1 2" SnapsToDevicePixels="true" StrokeThickness="1" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Setter.Value>
</Setter>
<Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
<Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Border x:Name="border" Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" SnapsToDevicePixels="true"/>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Background" Value="Black"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Background" Value="White"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Change the binding in your data template from Content to IsChecked.
<DataTemplate x:Key="DataTemplate_Level2">
<ToggleButton IsChecked="{Binding}" Height="15" Width="15" Margin="1,1,1,1" Style="{DynamicResource MyToggleButtonStyle}"/>
</DataTemplate>
This buys you the advantage of toggling the states automatically, but only if you can provide a property for two-way binding (getter and setter), otherwise an exception will be thrown.

Remove Border around Button

I've been trying to remove the Border around a Button and also change the Colour of the Button's Background when the mouse hovers over it.
Here is what I have:
<Button Name="Home" Content="Home" HorizontalAlignment="Left" Width="75" Click="Button_Click_Home" Background="#FF252525" FontFamily="/VideoManager;component/#Myriad Pro" FontSize="13.333" Foreground="White" BorderThickness="5">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderThickness="0"/>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#FF36290A"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
The issue is that regardless of what I set BorderThickness to, the Button disappears. Also the Button is not changing to the colour I specified with the Trigger.
I also tried simply using a Style Setter but found this had no effect on my Button.
<Style TargetType="{x:Type Button}">
<Setter Property="BorderThickness" Value="0"/>
</Style>
You need to define following ControlTemplate and remove Style Trigger.
<ControlTemplate TargetType="{x:Type Button}">
<Border Name="border"
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver"
Value="True">
<Setter TargetName="border"
Property="Background"
Value="#FF36290A" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
I have tried this and this is working.
I have a style that I use to remove the default Windows style from buttons ; I'm sure you can use it or use it to achieve what you want. As it is, it just makes a button with absolutely no border, no background, no margins, nothing, just play with the template to achieve what you want :
<Style x:Key="NoChromeButton" TargetType="{x:Type Button}">
<Setter Property="Background" Value="Transparent"/>
<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}">
<Grid x:Name="Chrome" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="#ADADAD"/>
<Setter Property="Opacity" TargetName="Chrome" Value="0.5"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Cursor" Value="Hand"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
It is not mine but I don't remember where I found it, so sorry if the author come by !
You could also take the default button template from MSDN and tweak it.

Remove default Hover Blue color in a Wpf button [duplicate]

I'm trying to disable the MouseOver effect on buttons, or at least change the colour of it, in WPF.
I'm using the following style:
<Style x:Key="Borderless" TargetType="{x:Type Button}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Button Background="{TemplateBinding Control.Background}"
Focusable="False">
<ContentPresenter
Margin="{TemplateBinding Control.Padding}"
HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}"
ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"
RecognizesAccessKey="True"
Content="{TemplateBinding ContentControl.Content}" />
</Button>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
in Window.Resources, which I thought would override all the default behaviours. But it doesn't.
Any suggestions?
Look what your control template boils down to:
<ControlTemplate TargetType="{x:Type Button}">
<Button>
<ContentPresenter/>
</Button>
</ControlTemplate>
You're saying, "I want to replace the look of my button with... a button." The usage of the ControlTemplate is to replace the visual tree of a control. So you are replacing the visual tree of the existing button with another button. If you want to start a button from scratch, try using the SimpleStyles button:
<Style TargetType="{x:Type Button}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="MinHeight" Value="23"/>
<Setter Property="MinWidth" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Name="Border" CornerRadius="2" BorderThickness="1"
Background="#C0C0C0"
BorderBrush="#404040">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter TargetName="Border"
Property="BorderBrush" Value="#202020" />
</Trigger>
<Trigger Property="IsDefaulted" Value="true">
<Setter TargetName="Border"
Property="BorderBrush" Value="#202020" />
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border"
Property="Background" Value="#808080" />
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter TargetName="Border"
Property="Background" Value="#E0E0E0" />
<Setter TargetName="Border"
Property="BorderBrush" Value="#606060" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Border"
Property="Background" Value="#EEEEEE" />
<Setter TargetName="Border"
Property="BorderBrush" Value="#AAAAAA" />
<Setter Property="Foreground" Value="#888888"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Notice that this template creates a button the simplest possible way: a border that contains the button content. It does not use another button embedded inside the template.

ResourceDictionary Style Triggers not working

from the following Trigger only the Foreground Setter is working. I do not understand why.
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red"/>
<Setter Property="BorderBrush" Value="Red"/>
<Setter Property="Foreground" Value="Red"/>
</Trigger>
Thanks for any help.
The reason this doesn't work is because the default Button template uses a ButtonChrome that draws the border and background and handles states like mouseover and disabled depending on the Windows theme (e.g. Windows XP style, Windows 7 style).
In order to allow your triggers to be applied, you will need to define a custom Button template that uses standard stylable WPF elements, like Border, instead of ButtonChrome. Here's a bare-bones working example:
<Button Content="button">
<Button.Style>
<Style TargetType="Button">
<Setter Property="BorderThickness" Value="3" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Background="{TemplateBinding Property=Background}"
BorderBrush="{TemplateBinding Property=BorderBrush}"
BorderThickness="{TemplateBinding Property=BorderThickness}">
<ContentPresenter />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red" />
<Setter Property="BorderBrush" Value="Green" />
<Setter Property="Foreground" Value="Blue" />
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
Button in WPF has a default control template. The correct way to override the Button's default behavior is by overriding default control template. This can be done with something similar to below:
<Button Width="100" Height="50" Content="Click Me!">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="bdr_main" CornerRadius="20" Margin="4" BorderThickness="1" BorderBrush="Black" Background="LightGray">
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" Margin="8,6,8,6" ContentSource="Content" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="bdr_main" Property="Background" Value="LightGreen"/>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="bdr_main" Property="Background" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>

Hope it helps!
Try using the trigger on the controltemplate.
<ResourceDictionary>
<Style x:Key="TestButton" TargetType="Button">
<Setter Property="Height" Value="30" />
<Setter Property="Width" Value="30" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="Green" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Purple" />
</Trigger>
</ControlTemplate.Triggers>
<Grid>
<Rectangle Fill="{TemplateBinding Foreground}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
