silverlight列表框stackpanel项目通过模板化的项目值定义背景颜色

Question

I want to chang background color the border or stackpanel by binded item's value

 <controls:ChildWindow.Resources>
        <l:StringToColorConverter x:Key="converter"/>
    </controls:ChildWindow.Resources>
...
                <DataTemplate>
                    <StackPanel Orientation="Vertical">

                        <Border BorderBrush="Black" Background="{Binding Cím, Converter={StaticResource converter}}"  x:Name="hatter" BorderThickness="4" CornerRadius="20">
                            <StackPanel Style="{StaticResource dolgozostack}"
                                         Margin="2,2,2,2">
                                <TextBlock Text="{Binding Cím}" TextWrapping="Wrap" Foreground="White" FontSize="13" TextAlignment="Center" />
                            </StackPanel>
                        </Border>
                    </StackPanel>
                </DataTemplate>

And here is my converter:

    public class StringToColorConverter:IValueConverter
        {
            public object Convert(object value, Type targetType,
           object parameter, CultureInfo culture)
            {
                if (value.ToString().ToLower() == "Megvalósítás elindítva".ToLower())
                    return Colors.Green;
                else{
                     SolidColorBrush mybrush=new SolidColorBrush(Colors.Red);
                return mybrush;
}

            }
    }

Find its working with SolidColorBrush

You can do that by binding Background property that you want to change to item's value, and use Converter that will return specific color brush given specific value.

<TextBlock Text="{Binding Full_Name}" FontSize="16" TextAlignment="Center" TextWrapping="Wrap"
        Foreground="{Binding Full_Name, Converter={StaticResource ColorConverter}" />
