I've got a UserControl which is a modified toggleButton.
I've added two String properties to it so I can change (or bind) them in blend, which I want to be the text displayed when the button is toggled. ie when checked, one string is displayed, when unchecked - the other.
Setting the text is fine, and toggling the UserControl is fine, but I don't know how to set the content of the contentpresenter from a property of the toggle by a trigger. Here's a rough look at the code:
<UserControl
x:Name="UserControl"
<UserControl.Resources>
<Style x:Key="BiTextToggleButtonWithBorder" TargetType="{x:Type ToggleButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Grid>
<Path x:Name="path"
Data="M28,0.5 L28.071953,0.50129622 28.092436,0.5 115.90756,0.5 C117.89162,0.50000113 119.5,2.5147196 119.5,5.0000013 L119.61492,36.460156 119.61432,36.857203 C117.1338,37.367692 108.82679,39.239366 106.37993,47.492391 L44.667,47.5 28.092436,47.5 4.9999995,47.5 C2.5147185,47.5 0.5,45.485283 0.5,43 L0.5,21 0.51801485,20.64324 0.5,20.0835 C0.5,9.2678322 12.812169,0.50000072 28,0.5 z"
Stretch="Fill"
<ContentPresenter
x:Name="contentPresenter"
Content="{Binding}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content" TargetName="contentPresenter" Value="{Binding whatgoeshere!?}"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Content" TargetName="contentPresenter" Value="whatgoeshere!?"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
<Grid x:Name="LayoutRoot">
<ToggleButton
x:Name="ToggleButton"
Style="{DynamicResource BiTextToggleButtonWithBorder}"
FontSize="18.667"
Foreground="{DynamicResource WhiteText}"/>
</Grid>
</UserControl>
I can't even find the property I want to change. I've done similar bindings to objects within a UserControl before, but nothing that is in a style and in a controlpresenter.
What am I missing?
have you tried changing the {Binding} to a {TemplateBinding} ? (MSDN documentation here)

So I decided to try to give a button a custom style.
Yet when I assign it the Style it wont use it, why is this?
I tried creatinga button with a textbox, image and a ellipse with a label on that too.
I want the button to change color when I hover over it but its making my button disappear.
Window resources
<Window.Resources>
<Style x:Key="MenuButton" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<ControlTemplate.Triggers>
<Trigger Property="Background" Value="#272727">
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Gray"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
And then the button
<Button Background="Transparent"
Style="{StaticResource MenuButton}"
Height="25"
BorderThickness="0">
<StackPanel Orientation="Horizontal">
<Image Source="Resources/earth-globe.png"
Height="20"
Width="20"
HorizontalAlignment="Left"
Margin="0,0,5,0"
UseLayoutRounding="True"
RenderOptions.BitmapScalingMode="Fant"/>
<Label Content="Websites"
Foreground="White"
VerticalAlignment="Center"
Width="100"
Height="24"/>
<Grid HorizontalAlignment="Right" Height="20" Width="20">
<Ellipse Width="20"
Height="20"
Fill="#555555"
Margin="0,0,0,0">
</Ellipse>
<TextBlock Text="10"
HorizontalAlignment="Center"
VerticalAlignment="Center"
FontSize="12"
TextAlignment="Center"
Foreground="White"/>
</Grid>
</StackPanel>
</Button>
You do not want to put that style in the template portion of the style because a template is used for customizing the full control look (i.e. making a button a circle) and a way of giving the developer more flexibility over styling. What you could do is make a style that is applied to the button. Instead try this:
<Window.Resources>
<Style x:Key="MenuButton" TargetType="{x:Type Button}">
<Setter Property="Background" Value="#272727" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Gray" />
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
If you did want to modify the template property though, also a valid approach you need to add a <ContentPresenter />. See the below example:
<Window.Resources>
<Style x:Key="MenuButton" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<ContentPresenter />
<ControlTemplate.Triggers>
<Trigger Property="Background" Value="#272727">
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Gray"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
However, with the minimal styling you have it seems like a poor use case to modify the template and I would recommend the first approach.
Add missing ContentPresenter to your DataTemplate.
<Style x:Key="MenuButton" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<ContentPresenter /> <!--This thing was missing-->
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="RED" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I am having trouble accessing a named element of a parent template style in WPF.
I have a custom control for a Button (written per this StackOverflow question):
CustomButton.xaml:
<ResourceDictionary ...>
<Style x:Key="ButtonCustomStyle" TargetType="{x:Type local:ImageButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:ImageButton}">
<Grid>
<Image Source="{TemplateBinding Image}" Stretch="Fill" x:Name="CurrentImage"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="CurrentImage" Property="Source" Value="{Binding ImageHover, RelativeSource={RelativeSource TemplatedParent}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
MainWindow.xaml:
<Window ...>
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="CustomButton.xaml"/>
</ResourceDictionary.MergedDictionaries>
<Style TargetType="{x:Type local:ImageButton}" BasedOn="{StaticResource ButtonCustomStyle}"/>
</ResourceDictionary>
</Window.Resources>
<Grid>
<local:ImageButton Image="\Images\image.png" ImageHover="\Images\image_hover.png" Width="20" Height="20"/>
</Grid>
ImageButton inherits Button, and Image and ImageHover are defined as dependency properties. This code works great and does what expected.
Now, I want to extend this template style for a single particular button, adding an additional Trigger for changing the image of the button. I am trying to do the following:
<Window...>
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="CustomButton.xaml"/>
</ResourceDictionary.MergedDictionaries>
<Style TargetType="{x:Type local:ImageButton}" BasedOn="{StaticResource ButtonCustomStyle}"/>
<Style TargetType="{x:Type local:ImageButton}"
BasedOn="{StaticResource ButtonCustomStyle}"
x:Key="Disableable">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="CurrentImage" Property="Source" Value="\Images\disabled.png"/>
</Trigger>
</Style.Triggers>
</Style>
</ResourceDictionary>
</Window.Resources>
<Grid>
<local:ImageButton Image="\Images\image.png" ImageHover="\Images\image_hover.png" Width="20" Height="20"/>
<local:ImageButton Style="{StaticResource Disableable}" Image="\Images\image.png" ImageHover="\Images\image_hover.png" Width="20" Height="20"/>
</Grid>
But Visual Studio underscores the new setter line and says 'The name "CurrentImage" is not recognized'.
Is there a way to alter the CurrentImage element?
I am having trouble accessing a named element of a parent template style in WPF.
This is not possible. You can't base a ControlTemplate on another ControlTemplate.
I am afraid you will have to re-define the entire ControlTemplate from scratch in the derived Style if you want the setter to be able find the CurrentImage element that is defined in the template of the base Style.
WPF: Is there a way to override part of a ControlTemplate without redefining the whole style?
But instead of using a ControlTemplate trigger, you should be able to use a Style trigger that sets the Image property of the control itself rather than setting the Source property of the Image element in the template:
<Style x:Key="ButtonCustomStyle" TargetType="{x:Type local:ImageButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:ImageButton}">
<Grid>
<Image Source="{TemplateBinding Image}" Stretch="Fill" x:Name="CurrentImage"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Image" Value="{Binding ImageHover, RelativeSource={RelativeSource Self}}"/>
</Trigger>
</Style.Triggers>
</Style>
<Style TargetType="{x:Type local:ImageButton}"
BasedOn="{StaticResource ButtonCustomStyle}"
x:Key="Disableable">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Image" Value="\Images\disabled.png"/>
</Trigger>
</Style.Triggers>
</Style>
Unlike ControlTemplete trigger, Style trigger doesn't have access to template elements. since you exposed Image property, use it in Style trigger setter:
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Image" Value="\Images\disabled.png"/>
</Trigger>
I would like to make a game like Shakes & Fidgets. I got stuck at the Main menu, where I already overcomplicated stuff as I always do. I made a grid layout, where I will put the buttons, but every button is a picture. I use ImageBrush for every button's picture I want to create.
I would like to create ONE style for every button so they change their backgrounds based on the x:Name or x:Key they have. So a Button with x:Name or x:Key "PlayGame" would find it's as the PlayGame.png, PlayGame_Hover, PlayGame_OnClick where "PlayGame" is a variable.
In other words I would like to have a style that can filter the x:name, or x:key of a button, and uses it as a variable later on so I can do this: {StaticResource VARIABLENAME}
The Code I have now is:
<ImageBrush x:Key="PlayGame">
<ImageBrush.ImageSource>
<BitmapImage UriSource="./Pictures/PlayGameButton.png"/>
</ImageBrush.ImageSource>
</ImageBrush>
<ImageBrush x:Key="PlayGame_Hover">
<ImageBrush.ImageSource>
<BitmapImage UriSource="./Pictures/PlayGameButton_Hover.png"/>
</ImageBrush.ImageSource>
</ImageBrush>
<ImageBrush x:Key="PlayGame_OnClick">
<ImageBrush.ImageSource>
<BitmapImage UriSource="./Pictures/PlayGameButton_OnClick.png"/>
</ImageBrush.ImageSource>
</ImageBrush>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="{StaticResource PlayGame}" />
<Setter Property="FontSize" Value="15" />
<Setter Property="SnapsToDevicePixels" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border CornerRadius="4" Background="{TemplateBinding Background}">
<Grid>
<ContentPresenter x:Name="MyContentPresenter" Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,0,0,0" />
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{StaticResource PlayGame_Hover}" />
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="{StaticResource PlayGame_OnClick}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I found a not very effective solution, but not the one I actually want
You can give the Style an
x:Key="styleKey"
and you have to give the button this part:
Style="{StaticResource styleKey}"
This way you will have to make a style for every different button you want to have, but it will work, and you will be happy about it if efficency is not key.:D
I'm currently trying to do the following:
If no password is entered a text "Password" should be shown.
But with my template no password is shown, and if i'm using a decorator or a scrollviewer i can't change the color of the text.
Do you have any ideas to achieve this?
Here's my styling code:
<Style TargetType="{x:Type PasswordBox}" x:Key="Password">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="PasswordBox">
<Grid>
<PasswordBox Background="{StaticResource BrushDark}" Foreground="{StaticResource BrushTextNormal}" BorderBrush="{StaticResource BrushBorderInput}" BorderThickness="1"/>
<TextBlock HorizontalAlignment="Left"
VerticalAlignment="Center"
Text="Password"
Margin="5,0,5,0"
Foreground="#ff808080"
IsHitTestVisible="False"
x:Name="UserMessage"
Visibility="Hidden"/>
<!--<ScrollViewer Foreground="{StaticResource BrushTextNormal}" Background="{StaticResource BrushTextNormal}" x:Name="PART_ContentHost"/>-->
<!--<Decorator TextBlock.Foreground="White" x:Name="PART_ContentHost"/>-->
</Grid>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="Tag" Value=""/>
<Condition Property="IsKeyboardFocusWithin" Value="False"/>
</MultiTrigger.Conditions>
<Setter Property="Visibility" TargetName="UserMessage" Value="Visible"/>
</MultiTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
If you create custom ControlTemplate for PasswordBox or TextBox you need to put ScrollViewer named x:Name="PART_ContentHost instead of inner PasswordBox
From PasswordBox Syles and Templates
PART_ContentHost - A visual element that can contain a FrameworkElement. The text of the PasswordBox is displayed in this element.
And change Foreground as another Setter in you Style. Also, as a side node, I would do the same with Background and use TemplateBinding in your ControlTemplate. This will give more flexibility and allow you to change Background and/or Foreground manually without changing ControlTemplate
<Style TargetType="{x:Type PasswordBox}" x:Key="Password">
<Setter Property="Foreground" Value="{StaticResource BrushTextNormal}" />
<Setter Property="Background" Value="{StaticResource BrushDark}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type PasswordBox}">
<Grid Background="{TemplateBinding Background}">
<ScrollViewer x:Name="PART_ContentHost" .../>
<TextBlock .../>
</Grid>
<ControlTemplate.Triggers>
<!-- removed -->
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I'm trying to customize my ToggleButtons so that when checked they say 'Yes' in green and when not checked, say 'No' in red.
I've created the following style which is sitting in my Styles resource dictionary.
<!-- ToggleButtons -->
<Style x:Key="YesNoToggleStyle" TargetType="ToggleButton">
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Background" Value="SpringGreen" />
<Setter Property="Content">
<Setter.Value>
<TextBlock Text="Yes"/>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Background" Value="Crimson" />
<Setter Property="Content">
<Setter.Value>
<TextBlock Text="No"/>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
This works ... sort of. If the ToggleButton is the last one of either value, then it displays correctly. All previous buttons with the same value are blank. The height was also shrinking, but I fixed that with the 'Height' Setter above the triggers. To illustrate, when a new record is being created it looks like:
and after I've clicked buttons 1, 2, and 3 and 1 again:
I originally had the style referenced from the surrounding grid:
<Grid>
...
<Grid.Resources>
<Style BasedOn="{StaticResource YesNoToggleStyle}" TargetType="{x:Type ToggleButton}" />
</Grid.Resources>
But changing that so each ToggleButton references the style individually (<ToggleButton Style="{StaticResource YesNoToggleStyle}" ... />) hasn't made a difference.
I looked at Customizing the toggle state of a toggle button in wpf, and Override ToggleButton Style where the effect is the same, but they talk about external images, and my issues is all within wpf.
I also looked at the second answer to: i want to change backcolor of toggle button when toggle button ischecked and viceversa in WPF but a) I only have the blend + sketchflow preview that comes with VS2012, and b) i'm a total noob with blend and can't get from Select the "Checked State" to Reset the Background Color instruction in the answer (plus i'd be surprised if this task requires the blend tool).
Can anyone show me what to do to get multiple ToggleButtons to use the same style properly?
This works for me. Somewhere in Dictionary1.xaml:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="YesNoToggleStyle" TargetType="{x:Type ToggleButton}" BasedOn="{StaticResource {x:Static ToolBar.ToggleButtonStyleKey}}">
<Style.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Background" Value="Crimson" />
<Setter Property="Content" Value="No"/>
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Background" Value="SpringGreen" />
<Setter Property="Content" Value="Yes"/>
</Trigger>
</Style.Triggers>
</Style>
</ResourceDictionary>
Note, that style is based on ToolBar.ToggleButtonStyle.
<Grid>
<Grid.Resources>
<ResourceDictionary Source="pack://application:,,,/Dictionary1.xaml"/>
</Grid.Resources>
<ItemsControl ItemContainerStyle="{StaticResource YesNoToggleStyle}">
<ToggleButton />
<ToggleButton />
<ToggleButton />
</ItemsControl>
</Grid>
try to replace Content property to ContentTemplate:
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock Text="Yes"/>
</DataTemplate>
</Setter.Value>
</Setter>
In my case I wanted to have a "Locked" ToggleButton in a common dll defined and reused across my Apps.
Here's my result, which worked for me. Maybe someone find it useful (put this in a Resourcedictionary.xaml):
<BitmapImage x:Key="LockedLock"
UriSource="/...;component/Resources/Lock_closed_16p.png" />
<BitmapImage x:Key="OpenLock"
UriSource="/...;component/Resources/Lock_open_16p.png" />
<Style x:Key="LockButton"
TargetType="ToggleButton">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Image Source="{DynamicResource OpenLock }"
Width="12"
Height="12"
Name="contentimage" />
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=ToggleButton , AncestorLevel=1, Mode=FindAncestor }, Path=IsChecked}"
Value="True">
<Setter Property="Image.Source"
TargetName="contentimage"
Value="{DynamicResource LockedLock }" />
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
