WPF - changing background button - wpf

Question

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>
