While learning WPF, I've created a style, that applies rounded corners to a textbox and also set the background color, if the control has the focus:
<Style TargetType="TextBox" x:Name="efTextBoxStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate >
<Border x:Name="border" BorderThickness="1" CornerRadius="2">
<ScrollViewer x:Name="PART_ContentHost"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter TargetName="border" Property="BorderBrush" Value="Red"/>
<Setter Property="Background" Value="Blue"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
At runtime if the control gets the focus, the border is rendered as expected in red color, but the background color of the textbox doesn't change to blue.
What's wrong?
Setter mus have a TargetName else it won't know where to set the value.
In your case:
<Setter TargetName="border" Property="Background" Value="Blue"/>
That might sound a bit confusing, but for the Background you need your TargetName="border"
For the foreground on the other hand side, you wouldn't need:
<Style TargetType="TextBox" x:Name="efTextBoxStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate x:Name="bal">
<Border x:Name="border" BorderThickness="1" CornerRadius="2">
<ScrollViewer x:Name="PART_ContentHost"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter TargetName="border" Property="BorderBrush" Value="Red"/>
<Setter TargetName="border" Property="Background" Value="blue"/>
<Setter Property="Foreground" Value="yellow"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

This is part of my custom datagrid appearance.
<Style x:Key="DatagridStyle_1" TargetType="DataGrid">
<!--<Setter Property="ColumnHeaderStyle" Value="{DynamicResource Datagrid_HearderStyle_1}"/>
<Setter Property="CellStyle" Value="{DynamicResource Datagrid_CellStyle_1}"/>-->

<Setter Property="AlternationCount" Value="2"/>

<Style x:Key="ConTemplate_DgRow_1" TargetType="{x:Type DataGridRow}">
<Setter Property="Background" Value="White"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="DataGridRow">
<Grid SnapsToDevicePixels="True" Background="Transparent">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="1"
>
</Border>
<DataGridCellsPresenter Grid.Column="1"
ItemsPanel="{TemplateBinding ItemsPanel}"
/>
</Grid>
<!--<Border BorderThickness="1" Background="LightGreen" SnapsToDevicePixels="True">
<DataGridCellsPresenter Grid.Column="1" ItemsPanel="{TemplateBinding ItemsPanel}"/>
</Border>-->
<ControlTemplate.Triggers>
<!--<Trigger Property="IsSelected" Value="true">
<Setter Property="BorderBrush" Value="#00BCD4"/>
</Trigger>-->
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="BorderBrush" Value="#00BCD4"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="AlternationIndex" Value="0">
<Setter Property="Background" Value="DarkBlue"/>
<Setter Property="Foreground" Value="LightGreen"/>
</Trigger>
</Style.Triggers>
</Style>
this part doesn't work,but the other part
<Setter Property="Foreground" Value="LightGreen"/> works fine
In the above code, I set the AlternationIndex trigger in the penultimate part of the code. In the same trigger, the Foreground property has already taken effect, but the Background property has never taken effect. I have modified the cell template and datagrid template before, and set their background color to transparent, but it has no effect.
I'd like to understand why this is the case and how to make setting the background color work.
So I have the following style in my Window.Resources:
<Style TargetType="TabItem" x:Key="tiS">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Grid Height="40" Width="186">
<Border Name="tiBorder" Background="Transparent">
<ContentPresenter ContentSource="Header"
VerticalAlignment="Center"
HorizontalAlignment="Center"
TextBlock.FontSize="20"/>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="90"/>
<Setter TargetName="tiBorder" Property="Background" Value="{DynamicResource tiB}"/>
<!--<Setter TargetName="tiBorder" Property="Margin" Value="0,-4,0,-4"/>-->
<Setter TargetName="tiBorder" Property="BorderThickness" Value="0,0,0,1"/>
<Setter TargetName="tiBorder" Property="BorderBrush" Value="{StaticResource tiLineFade}"/>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter Property="Panel.ZIndex" Value="80"/>
<Setter TargetName="tiBorder" Property="BorderThickness" Value="0,0,0,1"/>
<Setter TargetName="tiBorder" Property="BorderBrush" Value="{StaticResource tiLineFade}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
This style is used on 5 TabItems, each with a different color given by 'DynamicResource tiB' in the trigger.
In each TabItem I have the following resource placed (Color1 is set in the Window.Resources):
<TabItem.Resources>
<SolidColorBrush x:Key="tiB" Color="{StaticResource Color1}"/>
</TabItem.Resources>
I was wondering, is there an easier way to do this or am I doing it right? This is the first time I'm working with styles in WPF so I want to do it right. (This code is working! Looking for a better (if there is one) solution to my situation.)
Here is the full code: http://pastebin.com/igwxgp6M
I believe this will work
<TabControl ...>
<TabControl.ItemsContainerStyle>
<Style TargetType="TabItem">
//Put triggers here
</Style>
<TabControl.ItemsContainerStyle>
</TabControl>
In Windows7 (maybe vista too), TextBoxes now get a blue emphasis rect when they receive input focus or get the MouseOver.
In my WPF app, that blue focus rect really sticks out like a sore thumb - it does NOT match the visual style of the rest of the app.
How do I disable it - or better yet, customise it?
(Setting FocusVisualStyle to {x:Null} in the xaml does nothing.)
This is because of the default style applied for the TextBox. To modify this behavior you have to create a custom style/template. just have a look at this sample
<Style x:Key="TextBoxStyle1" BasedOn="{x:Null}" TargetType="{x:Type TextBox}">
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="AllowDrop" Value="true"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="ScrollViewer.PanningMode" Value="VerticalFirst"/>
<Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border x:Name="border" Background="#FF8F8F8F" BorderBrush="#FF585858" CornerRadius="3" BorderThickness="2">
<ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="BorderBrush" TargetName="border" Value="Silver"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" TargetName="border" Value="0.15"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" TargetName="border" Value="Silver"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I have built an UserControl. I don't like the red border showing around it when validation errors occur. I have a textbox inside my control.
How can I override the validation error style to get rid of the red border in the whole control and just show a red background in the textbox inside my usercontrol?
Thanks!
I am using this template that will color the background of the textbox instead of showing just the border.
<UserControl.Resources>
<Style TargetType="{x:Type TextBox}">
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="true" >
<Setter Property="Foreground" Value="Red"/>
<Setter Property="Background" Value="MistyRose"/>
<Setter Property="BorderBrush" Value="Red"/>
<Setter Property="BorderThickness" Value="1.0"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource
Self},Path=(Validation.Errors)[0].ErrorContent}"/>
</Trigger>
</Style.Triggers>
</Style>
</UserControl.Resources>
And all I have to do to your DocPannel Where the controls are located for example for me inside a DockPanel then i have to set its Validation.Error template to nothing this will remove the border.
For Ex:
<TextBox >
<Validation.ErrorTemplate>
<ControlTemplate>
</ControlTemplate>
</Validation.ErrorTemplate>
</TextBox>
On the style for your user control:
<Setter Property="Validation.ErrorTemplate" Value="{x:Null}"/>
On the style for your textbox:
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBoxBase}">
<Border
Name="Border"
CornerRadius="5"
Padding="2"
BorderBrush="{TemplateBinding BorderBrush}"
Background="{TemplateBinding Background}"
BorderThickness="{TemplateBinding BorderThickness}" >
<ScrollViewer Margin="0" x:Name="PART_ContentHost"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Border" Property="Background" Value="LightGray"/>
<Setter TargetName="Border" Property="BorderBrush" Value="Black"/>
<Setter Property="Foreground" Value="Gray"/>
</Trigger>
<Trigger Property="Validation.HasError" Value="true">
<Setter Property="BorderBrush" TargetName="Border" Value="{DynamicResource ErrorBorderColor}"/>
<Setter Property="Background" TargetName="Border" Value="{DynamicResource ErrorBackgroundColor}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
I have a minor issue. We'd like to put as much stylistic items in the styles and outside of the control templates, to make themeing easier. So for the scrollbar's repeatbutton, I can get all of this to work but IsPressed. That only works from the template.
So the template is (basically):
<ControlTemplate x:Key="ScrollBarButtonCT" TargetType="{x:Type RepeatButton}">
<Border
x:Name="borderRepeatButton"
Margin="1"
CornerRadius="2"
Background="{TemplateBinding Background}">
<Path x:Name="pathArrow"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Fill="{DynamicResource ThumbBrush}"
Data="{Binding Content, RelativeSource={RelativeSource TemplatedParent}}" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="true">
<Setter TargetName="borderRepeatButton" Property="Background" Value="{DynamicResource ThumbPressedBrush}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
And the style is
<Style x:Key="ScrollBarButtonStyle" TargetType="{x:Type RepeatButton}">
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Focusable" Value="false"/>
<Setter Property="IsTabStop" Value="false"/>
<Setter Property="Background" Value="{DynamicResource ScrollBarBGBrush}"/> <!-- borderRepeatButton -->
<Setter Property="OpacityMask" Value="{DynamicResource ThumbBrush}"/> <!-- pathArrow-->
<Setter Property="Template" Value="{StaticResource ScrollBarButtonCT}"/>
<Style.Triggers>
<!--<Trigger Property="IsPressed" Value="true"> .... this doesn't work coming from the style
<Setter Property="Background" Value="{DynamicResource ThumbPressedBrush}" />
</Trigger>-->
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="{DynamicResource ScrollBarDisabledBGBrush}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="{DynamicResource ThumbHoverBrush}"/>
</Trigger>
</Style.Triggers>
</Style>
I can't get IsPressed to work from the style. Looking in Snoop IsPressed is raised just fine when using the control. What am I doing wrong? Thanks!
No idea why it doesnt work, maybe it needs static resource? u can try this to get all styles in one place.
<Style x:Key="xxxtyle" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Fill" TargetName="rectangle" Value="#FFD5D5D5"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
ps TargetType="typeName" == TargetType="{x:Type typename}"
I know this is old, but it turns out this must be a bug in the template. We could never get it to work, and talking to some people on the inside more or less confirmed it. We just left the value in the template and worked around it by swapping templates when we needed a different RepeatButton style.
