<DataTemplate>
<Border BorderThickness="1" Width="18" Height="18" CornerRadius="2" BorderBrush="Red" Background="Red">

</DataTrigger>
<DataTrigger Binding="{Binding RowData.DataContext.my}" Value="Medium">
<Setter Property="Source" Value="/project;component/Images/Medium.png" />
</DataTrigger>

</DataTrigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
</Border>
</DataTemplate>
Thank you.
Assuming that your Binding is correct, you just need to add a similar Style to the Border to update the Background property and remove the Background value from the Border itself:
<DataTemplate>
<Border BorderThickness="1" Width="18" Height="18" CornerRadius="2" BorderBrush="Red">
<Border.Style>
<Style TargetType="{x:Type Border}">
<Style.Triggers>
<DataTrigger Binding="{Binding RowData.DataContext.my}" Value="High">
<Setter Property="Background" Value="Green" />
</DataTrigger>
<DataTrigger Binding="{Binding RowData.DataContext.my}" Value="Medium">
<Setter Property="Background" Value="Blue" />
</DataTrigger>
<DataTrigger Binding="{Binding RowData.DataContext.my}" Value="Low">
<Setter Property="Background" Value="Red" />
</DataTrigger>
</Style.Triggers>
</Style>
</Border.Style>
<Image Width="16" Height="16">
<Image.Style>
<Style TargetType="{x:Type Image}">
<Setter Property="Source" Value="{x:Null}" />
<Style.Triggers>
<DataTrigger Binding="{Binding RowData.DataContext.my}" Value="High">
<Setter Property="Source" Value="/project;component/Images/High.png" />
</DataTrigger>
<DataTrigger Binding="{Binding RowData.DataContext.my}" Value="Medium">
<Setter Property="Source" Value="/project;component/Images/Medium.png" />
</DataTrigger>
<DataTrigger Binding="{Binding RowData.DataContext.my}" Value="Low">
<Setter Property="Source" Value="/project;component/Images/Low.png" />
</DataTrigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
</Border>
</DataTemplate>
Try this.

I've been struggeling with this issue today when as soon as I try to bind a data trigger on a button I get this issue and I can't find our the issue. The button is contained in a listview which is bound to a dataset.
There is my button code:
<Button
Grid.Row="1"
Grid.Column="0"
Click="BtnAddToCart_Click"
MinWidth="230">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Visibility" Value="Hidden"/>
<Setter Property="Margin" Value="7,5,0,0"/>
<Style.Triggers>
<DataTrigger Binding="{Binding Path=OrderQty, Converter={StaticResource GreaterThanZero}}" Value="True">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
<Button.Template>
<ControlTemplate>
<WrapPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<WrapPanel.Style>
<Style TargetType="{x:Type WrapPanel}">
<Setter Property="Background" Value="#ec3c42"/>
<Setter Property="TextBlock.Foreground" Value="White"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="White"/>
<Setter Property="Cursor" Value="Hand"></Setter>
<Setter Property="TextBlock.Foreground" Value="#ec3c42"></Setter>
</Trigger>
</Style.Triggers>
</Style>
</WrapPanel.Style>
<WrapPanel.Resources>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="Padding" Value="10,10" />
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="FontSize" Value="15"/>
</Style>
</WrapPanel.Resources>
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="Ajouter aux Commandes"></TextBlock>
<fa:FontAwesome Visibility="Hidden" VerticalAlignment="Center" HorizontalAlignment="Right" Icon="check">
<fa:FontAwesome.Triggers>
<DataTrigger Binding="{Binding Path=ShowAsChecked}" Value="true">
<Setter Property="Visibility" Value="Visible"></Setter>
</DataTrigger>
</fa:FontAwesome.Triggers>
</fa:FontAwesome>
</WrapPanel>
</ControlTemplate>
</Button.Template>
</Button>
The issue seems to happen when I add this piece of code:
<fa:FontAwesome.Triggers>
<DataTrigger Binding="{Binding Path=ShowAsChecked}" Value="true">
<Setter Property="Visibility" Value="Visible"></Setter>
</DataTrigger>
</fa:FontAwesome.Triggers>
When I remove the trigger the code run as expected.
Even when I bind it to a property that is working on a different level it doesn't work.
I tried changing the binding to:
Binding="{Binding Path=OrderQty, Converter={StaticResource GreaterThanZero}}
and it's still giving me the error. I tried to look up some code example but didn't find anything about that issue (since the error is pretty common it's hard to tell what is going on).
Try
<fa:FontAwesome Visibility="Hidden" VerticalAlignment="Center" HorizontalAlignment="Right" Icon="check">
<fa:FontAwesome.Style>
<Style TargetType="fa:FontAwesome">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=ShowAsChecked}" Value="true">
<Setter Property="Visibility" Value="Visible"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</fa:FontAwesome.Style>
</fa:FontAwesome>
i would like change background color using binding. When i dont use Style="{DynamicResource ButtonStyle}", Background changes. This is my code:
<Button Style="{DynamicResource ButtonStyle}" Content="{Binding Title, UpdateSourceTrigger=PropertyChanged}"
Command="{Binding RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}, Path=DataContext.SelectButton}"
CommandParameter="{Binding}" ToolTip="{Binding Description}">
<Button.Resources>
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected, UpdateSourceTrigger=PropertyChanged}" Value="True">
<Setter Property="Background" Value="Red"></Setter>
</DataTrigger>
<DataTrigger Binding="{Binding IsSelected, UpdateSourceTrigger=PropertyChanged}" Value="False">
<Setter Property="Background" Value="Blue"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Resources>
</Button>
How i change background color in button using trigger? can be a trigger to insert a reference to style?
You could use a value converter instead a style if you cannot apply the trigger to the control template of the button or the style.
Background="{Binding IsSelected, Converter={StaticResource SelectedToBackgroundConverter}}"
Or with style
<Style x:Key="ButtonStyle2" TargetType="{x:Type Button}">
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected}" Value="True">
<Setter Property="Background" Value="Red"/>
</DataTrigger>
<DataTrigger Binding="{Binding IsSelected}" Value="False">
<Setter Property="Background" Value="Blue"/>
</DataTrigger>
</Style.Triggers>
</Style>
Or control template
<Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid x:Name="myGrid" Width="200" Height="20" Background="{TemplateBinding Background}">
</Grid>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding IsSelected}" Value="True">
<Setter TargetName="myGrid" Property="Background" Value="Red"/>
</DataTrigger>
<DataTrigger Binding="{Binding IsSelected}" Value="False">
<Setter TargetName="myGrid" Property="Background" Value="Blue"/>
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
How should i change the background of the wpftoolkit autocompletebox.? I tried by subscribing to enabledchanged event and changed the background of the control which is not changing at all.Can any body help.
<WpfToolkit:AutoCompleteBox x:Name="txtBxSearch" Background="White" IsTextCompletionEnabled="True" MinimumPrefixLength="0" FilterMode="Contains" Height="24" Width="150" KeyDown="txtBxSearch_KeyDown" >
<WpfToolkit:AutoCompleteBox.TextBoxStyle>

<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="FocusManager.FocusedElement" Value="{Binding RelativeSource={RelativeSource Self}}"/>
</Style>
</WpfToolkit:AutoCompleteBox.TextBoxStyle>
</WpfToolkit:AutoCompleteBox>
You can do this in XAML:
<toolkit:AutoCompleteBox
ToolTip="Enter the path of an assembly."
x:Name="tbAssembly" Height="27" Width="200"
Populating="tbAssembly_Populating"
>
<toolkit:AutoCompleteBox.Style>
<Style TargetType="toolkit:AutoCompleteBox">
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=tbAssembly, Path=IsEnabled}" Value="True">
<Setter Property="Background" Value="Yellow" />
<Setter Property="Foreground" Value="Red" />
</DataTrigger>
<DataTrigger Binding="{Binding ElementName=tbAssembly, Path=IsEnabled}" Value="False">
<Setter Property="Background" Value="Black" />
<Setter Property="Foreground" Value="Yellow" />
</DataTrigger>
</Style.Triggers>
</Style>
</toolkit:AutoCompleteBox.Style>
</toolkit:AutoCompleteBox>

I have the "Folder" context (its hierarchical object) but how can i bind to theTreeView properties in HierarchicalDataTemplate.Triggers? When i start this, output shows that there is no IsExpanded property in Folder object. So, i have wrong context.
<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=TreeViewItem}, Path=IsExpanded}" Value="true">
<Setter TargetName="imgFolderIcon" Property="Source" Value="/Resources/FolderExpanded.png" />
</DataTrigger>
Easy
I want to change button image when button IsEnabled == False.
Below is my example, bindings are fine, when I change them for False/True it is still not working.
<Button x:Name="btnBackward" Grid.Column="0" Grid.Row="2" Command="{Binding UserWorkflowManager.NavigateBackward}" IsEnabled="{Binding UserWorkflowManager.NavigateBackwardEnable}" Grid.RowSpan="2">
<Button.Template>
<ControlTemplate>
<Image Name="_image" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Uniform">
<Image.Style>
<Style TargetType="Image">
<Setter Property="Source" Value="/UserWorkflow.View;component/Images/LDC500_butX_PreviousPane_norm.bmp" />
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=btnBackward, Path=IsEnabled}" Value="False">
<Setter Property="Source" Value="/UserWorkflow.View;component/Images/LDC500_butX_PreviousPane_dis.bmp"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
</ControlTemplate>
</Button.Template>
</Button>
Try the following
<Style.Triggers>
<DataTrigger Binding="{Binding IsEnabled,RelativeSource={RelativeSource AncestorType=Button}}" Value="False">
<Setter Property="Source" Value="/UserWorkflow.View;component/Images/LDC500_butX_PreviousPane_dis.bmp"/>
</DataTrigger>
</Style.Triggers>
Or add the trigger directly in the control template like so
<ControlTemplate>
<Image Name="_image" HorizontalAlignment="Center">
..........
</Image>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="_image" Property="Source" Value="/UserWorkflow.View;component/Images/LDC500_butX_PreviousPane_dis.bmp" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Try this:
<Button x:Name="btnBackward" Grid.Column="0" Click="btnBackward_Click">
<Button.Template>
<ControlTemplate>
<Image Name="_image" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Uniform">
<Image.Style>
<Style TargetType="Image">
<Setter Property="Source" Value="/Images/0.png" />
</Style>
</Image.Style>
</Image>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Source" Value="/Images/1.png" TargetName="_image"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
You should specify "TargetName" property for a setter within "ControlTemplate.Triggers"
The soution is is to use RelativeSource={RelativeSource Self}} in your DataTrigger.
<DataTrigger
Binding="{Binding Path=IsEnabled, RelativeSource={RelativeSource Self}}"
Value="False">
Example
Add this style:
<Style x:Key="MainButtonStyle" TargetType="Button" BasedOn="{StaticResource ChromelessButtonStyle}">
<Setter Property="Foreground" Value="Black" />
<Style.Triggers>
<DataTrigger Binding="{Binding Path=IsEnabled, RelativeSource={RelativeSource Self}}" Value="True">
<Setter Property="Background" Value="Green" />
</DataTrigger>
<DataTrigger Binding="{Binding Path=IsEnabled, RelativeSource={RelativeSource Self}}" Value="False">
<Setter Property="Background" Value="Blue" />
</DataTrigger>
</Style.Triggers>
</Style>
Then apply this style to the button:
<Button x:Name="ActionButton" Style="{StaticResource MainButtonStyle}" Command="{Binding MyCmd}" IsEnabled="{Binding ActionButtonEnabled}"/>
