I have a global style for all comboboxes in application. For error validation I am using IDataErrorInfo. So when there will be error I want all textboxes to have such custom view:
with different ErrorContent (mouse should be over circle to show toolTip with error info). My combobox style is:
<Style x:Key="AlStyleTextBoxArial12" TargetType="{x:Type TextBox}">
<Setter Property="FontFamily" Value="Arial"/>
<Setter Property="FontSize" Value="12pt"/>
<Setter Property="Margin" Value="3,3,3,3"/>
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="True">
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<DockPanel LastChildFill="True">
<Grid DockPanel.Dock="Right" Margin="-23,0,0,0" Width="15" Height="15">
<Grid.ToolTip>
<ToolTip Content="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/>
</Grid.ToolTip>
<Ellipse Fill="Red" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
<TextBlock Text="!" VerticalAlignment="Center" HorizontalAlignment="Center" Foreground="White" FontSize="11pt" FontWeight="Bold" Margin="0,0,0,1"/>
</Grid>
<Border BorderBrush="Red" BorderThickness="1">
<AdornedElementPlaceholder/>
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
And my TextBox is implemented this way:
<TextBox Text="{Binding Snr, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}"
Grid.Row="3" Grid.Column="2"/>
View of the TextBox, when I have error, is ok, but I cannot set toolTip. It is always empty. Any ideas why I cann't get ErrorContent?
I've changed my style to this :
<Style x:Key="AlStyleTextBoxArial12" TargetType="{x:Type TextBox}">
<Setter Property="FontFamily" Value="Arial"/>
<Setter Property="FontSize" Value="12pt"/>
<Setter Property="Margin" Value="3,3,3,3"/>
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="True">
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate>
<DockPanel LastChildFill="True">
<Grid DockPanel.Dock="Right" Margin="-23,0,0,0" Width="15" Height="15">
<Grid.ToolTip>
<ToolTip Content="{Binding [0].ErrorContent}"/>
</Grid.ToolTip>
<Ellipse Fill="Red" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
<TextBlock Text="!" VerticalAlignment="Center" HorizontalAlignment="Center" Foreground="White" FontSize="11pt" FontWeight="Bold" Margin="0,0,0,1"/>
</Grid>
<Border BorderBrush="Red" BorderThickness="1">
<AdornedElementPlaceholder x:Name="customAdorner" ToolTip="{Binding [0].ErrorContent}"/>
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
and it is working now.

You can set style in resources
<Window.Resources>
<Style TargetType="{x:Type ListBox}">
<Setter Property="Background" Value="Gray" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Gray" />
<!--
Why you choose same background color when hover listbox
Maybe same color your background and foreground
-->
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
OR
Can you try below changes:
<DataTemplate>
<TextBlock Text="{Binding}" />
</DataTemplate>
<ContentPresenter
HorizontalAlignment="Center"
VerticalAlignment="Center"
Content="{Binding YourProp}" />
The problem is IsMouseOver is not working when I hover the button, though I have customized the button and it is not working.
Can you say where is the error?
<cc:CustomFlatButton Grid.Column="1"
Margin="1,0,5,4"
Command="{Binding ElementName=me, Path=Command疑い}"
CommandParameter="{Binding}"
IsEnabled="{Binding Path=疑いIsEnableFlag}">

I have also checked if I use trigger Property="IsMouseOver". It is also not working. Where is the problem?
You have changed the Button Template and in this Template no property is bound to the Backgroud of the button.
In the trigger, you change the value of this property, but since no one uses this property, nothing changes in the display.
There are two main options to solve.
Set the Border's background binding to the Backgroud property of the button:
<cc:CustomFlatButton Grid.Column="1"
Margin="1,0,5,4"
Command="{Binding ElementName=me, Path=Command疑い}"
CommandParameter="{Binding}"
IsEnabled="{Binding Path=疑いIsEnableFlag}">
<Run FontWeight="Bold">
疑い病名
</Run>
<Button.Style>
<Style TargetType="cc:CustomFlatButton">
<Setter Property="MinWidth" Value="80" />
<Setter Property="FontFamily" Value="メイリオ" />
<Setter Property="Background" Value="White"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type cc:CustomFlatButton}">
<Border Height="22"
Margin="1"
VerticalAlignment="Center"
Background="{TemplateBinding Background}"
BorderBrush="#FFFF5656"
BorderThickness="2"
CornerRadius="6"
RenderOptions.BitmapScalingMode="NearestNeighbor"
TextOptions.TextFormattingMode="Display"
UseLayoutRounding="True">
<Label Padding="0,1,0,0"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Content="{TemplateBinding Content}"
Foreground="Black" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="cc:CustomFlatButton.IsMouseOver" Value="True">
<Setter Property="Background" Value="DarkGoldenrod"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</cc:CustomFlatButton>
Or change the Border background with ControlTemplate triggers.
But this is applicable if CustomFlatButton is a Custom Control and not a UserControl.
That is, the CustomFlatButton should not have any predefined XAML.
<cc:CustomFlatButton Grid.Column="1"
Margin="1,0,5,4"
Command="{Binding ElementName=me, Path=Command疑い}"
CommandParameter="{Binding}"
IsEnabled="{Binding Path=疑いIsEnableFlag}">
<Run FontWeight="Bold">
疑い病名
</Run>
<Button.Style>
<Style TargetType="cc:CustomFlatButton">
<Setter Property="MinWidth" Value="80" />
<Setter Property="FontFamily" Value="メイリオ" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type cc:CustomFlatButton}">
<Border x:Name="PART_Border"
Height="22"
Margin="1"
VerticalAlignment="Center"
Background="White"
BorderBrush="#FFFF5656"
BorderThickness="2"
CornerRadius="6"
RenderOptions.BitmapScalingMode="NearestNeighbor"
TextOptions.TextFormattingMode="Display"
UseLayoutRounding="True">
<Label Padding="0,1,0,0"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Content="{TemplateBinding Content}"
Foreground="Black" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="cc:CustomFlatButton.IsMouseOver" Value="True">
<Setter Property="Background" Value="DarkGoldenrod" TargetName="PART_Border"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Style>
</cc:CustomFlatButton>
I am trying to change the TextBlock text colour whenever the Button is highlighted.
However, I don't know how to bind the ControlTemplate.Trigger to the TextBlock Foreground. I tried giving the TextBlock a Name and then using TargetName in Setter but it said that the name wasn't recognised.
<Button Name="Home" HorizontalAlignment="Left" Width="75" Click="Button_Click_Home" Background="#FF252525" BorderThickness="5">
<Button.Content>
<Grid HorizontalAlignment="Center" VerticalAlignment="Bottom">
<TextBlock FontFamily="/VideoManager;component/#Myriad Pro" FontSize="13.333" Foreground="White" Text="Home"></TextBlock>
</Grid>
</Button.Content>
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<ContentPresenter />
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="#FF360A0A" /> // What to put here..
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
this is going to help you, but it has a lot of loss, so i suggest to you to read more about Styles And Templates
<Button Name="Home" HorizontalAlignment="Left" Width="75" Background="#FF252525" BorderThickness="5">
<Button.Content>
<Grid HorizontalAlignment="Center" VerticalAlignment="Bottom">
<TextBlock FontFamily="/VideoManager;component/#Myriad Pro" FontSize="13.333" Text="Home"></TextBlock>
</Grid>
</Button.Content>
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Yellow" />
<Setter Property="Background" Value="Red" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
My button looks like this:
<Button ToolTip="Pending" Height="33" HorizontalAlignment="Right" Margin="0,5,379,0" Name="radButton2" VerticalAlignment="Top" Width="64" Background="#FF515151" BorderBrush="#FF515151" FontSize="14" Foreground="#FF5F5C5C" FontFamily="Mangal" Command="{Binding SetToPendingCommand}" IsEnabled="{Binding IsSetToPendingButtonEnabled}" Grid.Column="1" Grid.ColumnSpan="2">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderBrush="White" BorderThickness="1.5" CornerRadius="0">
<TextBlock Text="Pending" Foreground="White" TextAlignment="Center" FontSize="13" Margin="0,4, 0, 0" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
How do I get the mouseover to work correctly. I have tried not using a style and setting the template directly but that didnt't work either.
One way to do it is to move Triggers into ControlTemplate, give Border some name, for example x:Name="PART_Border", and then in the Setter you can specify TargetName="PART_Border":
<Button ...>
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderBrush="White" BorderThickness="1.5" CornerRadius="0" x:Name="PART_Border">
<TextBlock Text="Pending" Foreground="White" TextAlignment="Center" FontSize="13" Margin="0,4, 0, 0" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Red" TargetName="PART_Border"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Style>
</Button>
Move the trigger to ControlTemplate instead:
<ControlTemplate>
<Border BorderThickness="1.5" CornerRadius="0">
<TextBlock x:Name="txtBlock" Text="Pending" Foreground="White"
TextAlignment="Center" FontSize="13" Margin="0,4,0,0" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="txtBlock" Property="Background" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
All you need to do is add a template binding to the background property of the Border:
<Border Background="{TemplateBinding Background}" BorderBrush="White" BorderThickness="1.5" CornerRadius="0">
<TextBlock Text="Pending" Foreground="White" TextAlignment="Center" FontSize="13" Margin="0,4, 0, 0" />
</Border>
The important part is:
Background="{TemplateBinding Background}"
As it stands in the question the trigger is changing the template Background property, but that property is not being used within the control template.
I've been stylizing a TabControl in WPF XAML (.NET 4), all i can do is style a tab based on triggers or identically style them all. Is there any way that only the first tab is stylized different while the other tabs are stylized different than the first tab but the same as each other (a.k.a using the Tab Index to stylize a TabItem).
Thank you.
You can use AlternationCount and AlternationIndex:
<TabControl AlternationCount="{Binding Path=Items.Count,RelativeSource={RelativeSource Self}}">
<TabControl.ItemContainerStyle>
<Style TargetType="TabItem">
<Style.Triggers>
<Trigger Property="ItemsControl.AlternationIndex"
Value="0"> <!-- First item -->
<Setter Property="FontWeight"
Value="Bold"/>
</Trigger>
</Style.Triggers>
</Style>
</TabControl.ItemContainerStyle>
<TabItem Header="First"/>
<TabItem Header="Second"/>
<TabItem Header="Third"/>
<TabItem Header="Fourth"/>
</TabControl>
If you want to change the background color of just selected tab item then use that kind of style and apply that style to tab Item.
<Style TargetType="{x:Type TabItem}" x:Key="TabItemStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Background="Red" BorderBrush="#FF1467AF"
BorderThickness="1"
Margin="0,0,5,0" CornerRadius="8,8,0,0" SnapsToDevicePixels="True">
<TextBlock FontFamily="Arial" FontWeight="Bold" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Name="TextBlock" Foreground="White">
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="12,2,12,2"/>
</TextBlock>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="Border" Property="Background" Value="Yellow"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But if you want to just change the background color of First tab item then define two styles and apply one to first tab item and second one to other
Style for tab item 1:
<Style TargetType="{x:Type TabItem}" x:Key="TabItemStyleForFirst">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Background="Red" BorderBrush="#FF1467AF"
BorderThickness="1"
Margin="0,0,5,0" CornerRadius="8,8,0,0" SnapsToDevicePixels="True">
<TextBlock FontFamily="Arial" FontWeight="Bold" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Name="TextBlock" Foreground="White">
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="12,2,12,2"/>
</TextBlock>
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Style for other tab items:
<Style TargetType="{x:Type TabItem}" x:Key="TabItemStyleForOther">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Background="Yellow" BorderBrush="#FF1467AF"
BorderThickness="1"
Margin="0,0,5,0" CornerRadius="8,8,0,0" SnapsToDevicePixels="True">
<TextBlock FontFamily="Arial" FontWeight="Bold" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Name="TextBlock" Foreground="White">
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="12,2,12,2"/>
</TextBlock>
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
