I have these controls:
<Border Style="{StaticResource Button}">
<TextBlock>NEW</TextBlock>
</Border>
<Border Style="{StaticResource Button}">
<TextBlock>CLOSE</TextBlock>
</Border>
<Border Style="{StaticResource Button}">
<TextBlock>EXIT</TextBlock>
</Border>
And this style:
<Style x:Key="Button" TargetType="{x:Type Border}">
<Setter Property="Padding" Value="15, 10" />
<Setter Property="Margin" Value="5, 0" />
<Setter Property="MinWidth" Value="150" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Cursor" Value="Hand" />
</Trigger>
</Style.Triggers>
<Style.Resources>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="VerticalAlignment" Value="Center" />
</Style>
</Style.Resources>
</Style>
And I want to set each button/border to a specific, different color each, and another color for IsMouseOver.
I tried setting the Background on the control, but then the style can't overwrite the background and I can't do the IsMouseOver change.
I can only think of creating a different style for each one with their colors, but is there anyway to do a partial styling, like how you'd do in CSS?
<div class="button blue">NEW</div>
<div class="button red">CLOSE</div>
<div class="button gray">EXIT</div>
Or any other way to achieve this?
I haven't done any XAML in a while, so I'm a tad rusty. I'm pretty sure you can't do partial styles, but I know you can inherit styles using "BasedOn".
https://msdn.microsoft.com/en-us/library/system.windows.style.basedon(v=vs.110).aspx
This will allow you to do your base button style, and then create a color variant for each color you need based upon the common style features.
<Style x:Key="Button" TargetType="{x:Type Border}">
<Setter Property="Padding" Value="15, 10" />
<Setter Property="Margin" Value="5, 0" />
<Setter Property="MinWidth" Value="150" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Cursor" Value="Hand" />
</Trigger>
</Style.Triggers>
<Style.Resources>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="VerticalAlignment" Value="Center" />
</Style>
</Style.Resources>
</Style>
<Style x:Key="ButtonBlue" TargetType="{x:Type Border}" BasedOn="{StaticResource Button}">
<Setter Property="Background" Value="Blue" />
</Style>
Something like that, and then you use "ButtonBlue" instead of "Button" as the static resource you're referencing in the XAML for the control that you want to be blue. You should be able to add triggers as well in the inheriting style. Hopefully I'm remembering my syntax correctly.
Also, you may want to change the style Key to something other than "Button". Could be a bit confusing.

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 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 developed WPF code; I'm showing a figure like 0.77. But I want to show a figure like 0.7777.
I have two separate styles for both GridColumn and TextBox.
My code for gridcolumn is:
<Style TargetType="{x:Type dxg:GridColumn}" x:Key="dxGridColumnNumber" >
<Setter Property="ColumnHeaderContentStyle" Value="{DynamicResource dxHeaderContentControl}" />
<Setter Property="CellTemplate">
<Setter.Value>
<DataTemplate>
<dxe:TextEdit Name="PART_Editor" Mask="N2" MaskType="Numeric" HorizontalAlignment="Right" MaskUseAsDisplayFormat="True"/>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
Also This is for textbox:
<Style TargetType="{x:Type dxe:TextEdit}" x:Key="dxTextEditTutarText" BasedOn="{StaticResource dxTextEditBaseText}">
<Setter Property="MaskUseAsDisplayFormat" Value="True" />
<Setter Property="MaskType" Value="Numeric" />
<Setter Property="Mask" Value="N2" />
<Setter Property="HorizontalContentAlignment" Value="Right"/>
</Style>
Change the mask to "N4". In Your code, you set the mask to "N2" twice, which is unnecessary.
Just change
<Setter Property="Mask" Value="N2" />
to
<Setter Property="Mask" Value="N4" />
and remove Mask property in you TextExit (or the other way round)

I create an UWP App and define some styles like this:
<Style TargetType="TextBlock" >
<Setter Property="Foreground" Value="Orange" />
<Setter Property="Margin" Value="12" />
<Setter Property="FontSize" Value="18" />
So, all my TextBlocks are orange and have a margin of 12px. All fine. But now I want to define a second style for Headlines, which should be inherit the base style and just override the extra defined properties, like this:
<Style x:Key="HeadlineStyle" TargetType="TextBlock">
<Setter Property="FontSize" Value="32" />
But if I do it this way, all other style definitions are gone (no margin, no coloring).
So how could I keep the base style?
In WPF I can use the x:Type attribute and just say
BasedOn="{StaticResource {x:Type Button}}"
But x:Type are not available in UWP (and what I found it is no longer supported)
This does exactly what you want:
<Grid.Resources>
<Style TargetType="TextBlock" x:Key="medium">
<Setter Property="Foreground" Value="Orange"/>
<Setter Property="FontSize" Value="20"/>
</Style>
<Style TargetType="TextBlock" BasedOn="{StaticResource medium}">
<Setter Property="FontSize" Value="10"/>
</Style>
<Style TargetType="TextBlock" x:Key="bigger" BasedOn="{StaticResource medium}">
<Setter Property="FontSize" Value="30"/>
</Style>
</Grid.Resources>
<StackPanel>
<TextBlock Text="normal"/>
<TextBlock Text="medium" Style="{StaticResource medium}"/>
<TextBlock Text="bigger" Style="{StaticResource bigger}"/>
</StackPanel>
The first TextBlock is 10-px orange
The second TextBlock is 20-px orange
The third TextBlock is 30-px orange
I'm attempting to style the ListBoxItems within my listbox but the content of the ListBoxItem does not display and any change in colours are not apparent. The only thing working is the "border bottom" that I've applied to the bottom of each list item.
<Style x:Key="ListItemStyle" TargetType="{x:Type ListBoxItem}">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="MinHeight" Value="30" />
<Setter Property="Foreground" Value="Black" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderBrush="#FF66AFDE" BorderThickness="0 0 0 1" />
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="Background" Value="Red"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Use a panel/container/decorator in the ListBoxItem control template to set the background color. (It seems that the logic for setting the selection background color will interfere with attempts to control its background color.)
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border
Name="PART_Border"
Focusable="true"
Background="{TemplateBinding Background}"
BorderBrush="#FF66AFDE"
BorderThickness="0 0 0 1"
>
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter
Property="Background"
Value="Red"
TargetName="PART_Border"
/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Also note, that Border.Focusable is by default false. If setting it to true doesn't work (i admit, i haven't tested), use a different container control instead of Border.
Also, if the content you will show has any controls receiving focus (such as buttons or text fields), the trigger might not work as expected, because the Border might not have the focus when a control of the content has the focus. Also, tabbing from control to control might exhibit unexpected behaviour. If you have to deal with such a situation, try to handle the trigger in an ItemTemplate instead.
Regarding the ContentPresenter not showing anything: Depending on the type of the elements in the ItemsSource, you might need to define a ListBox.ItemTemplate (or ListBox.ItemTemplateSelector), otherwise ContentPresenter might not know what to display.
Try this
<Style x:Key="ListItemStyle" TargetType="{x:Type ListBoxItem}">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="MinHeight" Value="30" />
<Setter Property="Foreground" Value="Black" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border BorderBrush="#FF66AFDE" BorderThickness="0 0 0 1" x:Name="border">
<ContentPresenter/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter TargetName="border" Property="Background" Value="Red"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I hope this will help
