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>

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>
Hi I just wondered if I could get some help, I'm having alot of trouble getting the data trigger to work, if i remove the data trigger and place the drop shadow just as a setter it works. But i want to be able to give the user the option of turning on and off the drop shadow so I thought the data trigger would be the answer.
Basically I want to add the data trigger all over my control styles and just be able to change the fancyGraphics BOOL to TRUE or FALSE and have every controls drop shadow adjust.
Thanks in advance.
Here is my XAML
<sys:Boolean x:Key="fancyGraphics" >True</sys:Boolean>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="#EEE"></Setter>
<Setter Property="Foreground" Value="#555"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}" BorderThickness="1" BorderBrush="#DDD">
<Grid>
<ContentPresenter x:Name="MyContentPresenter" Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0" />
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#333"></Setter>
<Setter Property="BorderBrush" Value="#888"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<DataTrigger Binding="{Binding Path=fancyGraphics}" Value="True">
<Setter Property="Effect">
<Setter.Value>
<DropShadowEffect BlurRadius="20"
Opacity="0.5"
ShadowDepth="0"
Color="#111" />
</Setter.Value>
</Setter>
</DataTrigger>
</Style.Triggers>
</Style>
The binding in DataTrigger looks for a property named fancyGraphics. But, fancyGraphics is a static resource. You should define the binding as such:
<DataTrigger Binding="{Binding Source={StaticResource fancyGraphics}}" Value="True">
<Setter Property="Effect">
<Setter.Value>
<DropShadowEffect BlurRadius="20"
Opacity="0.5"
ShadowDepth="0"
Color="#111" />
</Setter.Value>
</Setter>
</DataTrigger>
I created a custom WPF control which displays the value of the Weight property which is an int. When the user clicks on the custom control or when the control gets the focus, the user should be able to edit the value of the Weight property.
To accomplish this, I tried the following:
If the control is "inactive", the Weight property will be displayed
in a TextBlock.
If the control gets the focus, the Weight property
will be displayed in a TextBox.
<ResourceDictionary

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfCustomControlLibrary1">
<Style TargetType="{x:Type local:CustomControl1}">
<Style.Resources>
<ControlTemplate x:Key="Control_Focused" >
<Border Background="Green"
BorderBrush="Black"
CornerRadius="50" Width="40" Height="40">
<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBox Width="35"
Text="{Binding Mode=TwoWay,Path=Model.Weight,UpdateSourceTrigger=PropertyChanged,RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type local:CustomControl1}}
,Converter={x:Static local:CustomControl1.IntToStringConverter}}" />
</StackPanel>
</Border>
</ControlTemplate>
<ControlTemplate x:Key="Control">
<Border Background="Green"
BorderBrush="Black"
CornerRadius="50" Width="40" Height="40">
<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBlock x:Name="PART_TextBlockWeighted" Text="{Binding Mode=TwoWay,Path=Model.Weight,UpdateSourceTrigger=PropertyChanged,RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type local:CustomControl1}}}"
HorizontalAlignment="Center" VerticalAlignment="Center" />
</StackPanel>
</Border>
</ControlTemplate>
</Style.Resources>
<Style.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="Template" Value="{StaticResource Control_Focused}" ></Setter>
</Trigger>
<Trigger Property="IsFocused" Value="False">
<Setter Property="Template" Value="{StaticResource Control}" ></Setter>
</Trigger>
</Style.Triggers>
</Style>
The problem with this custom control style is that when the user clicks into the TextBox, the trigger will change the control template to the TextBlock. How can I fix this?
Try using the IsKeyboardFocusWithin property instead. I believe this will do what you need.
<Style.Triggers>
<Trigger Property="IsKeyboardFocusWithin" Value="True">
<Setter Property="Template" Value="{StaticResource Control_Focused}" ></Setter>
</Trigger>
<Trigger Property="IsKeyboardFocusWithin" Value="False">
<Setter Property="Template" Value="{StaticResource Control}" ></Setter>
</Trigger>
</Style.Triggers>
I'm trying to make a template that will change a Button's background as well as the color of it's TextBlock. I tried the following XAML in my template, but it just makes the button dissapear on mouseover. Is there any way to change the properties of a buttons contents on triggers?
<ControlTemplate TargetType="{x:Type Button}">
<Border
x:Name="Border"
CornerRadius="0"
BorderThickness="0"
Background="{x:Null}"
BorderBrush="#FF404040" />
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border" Property="Background" Value="White" />
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate DataType="TextBlock">
<TextBlock Foreground="Blue" />
</DataTemplate>
</Setter.Value>
</Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
Style:
<Style TargetType="{x:Type Button}" x:Key="MyButton">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Border"
CornerRadius="0"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"
TextBlock.Foreground="{TemplateBinding Foreground}"
BorderBrush="#FF404040">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border" Property="Background" Value="White" />
<Setter TargetName="Border" Property="TextBlock.Foreground" Value="Blue" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Usage:
<Button Width="100" Height="50" Content="Lalala" Style="{StaticResource MyButton}" Background="Brown" Foreground="Green" BorderThickness="2"></Button>
You're missing the ContentPresenter, responsible for visualizing the Content property of the Button.
To set the foreground you can use TextBlock.Foreground attached property.
Control Styles and Templates has always been very usefull to me :)
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)
