如何从数据绑定中动态设置样式staticresource

我使用下面的代码来改变每个网格的样式

 <Grid HorizontalAlignment="Left" Width="453" Background="{StaticResource {Binding mystatus}}"  >

整个是

<phone:LongListSelector x:Name="MainLongListSelector" Margin="5,5" ItemsSource="{Binding TaskList}" SelectionChanged="MainLongListSelector_SelectionChanged" Foreground="Black" Height="654">
                <phone:LongListSelector.ItemTemplate>
                    <DataTemplate>
                        <Border Style="{StaticResource bordercss}" >
                            <Grid HorizontalAlignment="Left" Width="453" UseOptimizedManipulationRouting="True" Background="{StaticResource {Binding mystatus}}"  >
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition/>
                                    <ColumnDefinition Width="5*"/>
                                    <ColumnDefinition Width="6*" />
                                </Grid.ColumnDefinitions>
                                <Grid.RowDefinitions>
                                    <RowDefinition></RowDefinition>

                                <StackPanel Orientation="Vertical" Grid.Row="0" Grid.Column="1" >
                                   <TextBlock   Text="{Binding title}" Style="{StaticResource textbold}" Margin="5,0" />
                                    <TextBlock   Text="{Binding csoId}" Style="{StaticResource btbx}" Margin="5,0,5,5" HorizontalAlignment="Left" />

最后我得到了解决方案把这个道具放在Model

中

  private string _mystatus;
    public string mystatus
    {
        get
        {
            return _mystatus;
        }
        set
        {
            if (value != _mystatus)
            {
                _mystatus = value;
                NotifyPropertyChanged("mystatus");
                NotifyPropertyChanged("gridbgc");
                NotifyPropertyChanged("buttonfgc");
            }
        }
    }
    public string gridbgc
    {
        get
        {
            switch (mystatus)
            {
                case "Checked In":
                    return "#C8D7FF";
                case "Pending":
                    return "White";
                default:
                    return "White";
            }
        }
    }       
     public string buttonfgc
    {
        get
        {
            switch (mystatus)
            {
                case "Completed":
                    return "#6FCE2A";  
                case "Pending":
                    return "C03F40";
                default:
                    return "#6691EB";
            }
        }
    }

你可以通过“Binding Dynamicall Forecolor

获得这个

buttonfgc

   <TextBlock Text="{Binding mystatus}" Style="{StaticResource btbx}" Foreground="{Binding buttonfgc}"/>

如何从Windows Phone 8中的数据绑定设置样式staticresource
