Windows Phone 8.1 conditional formatting - xaml

Question

I would like to display some data on a ListView. The data is getting from a HttpClient request, but it's not so important at the moment. In the ListView I use Stackpanel and in this there are the datas. I would like to format the Stackpanel and the Textblocks inside the Stackpanel depending to their values. I can do it, but only in a complex way.
Here is my C# code:
public class TransTypeToAlignConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, string language)
{
var ttype = (int)value;
HorizontalAlignment align;
switch (ttype)
{
case 1:
case 3:
align = HorizontalAlignment.Right;
break;
case 2:
align = HorizontalAlignment.Left;
break;
case 6:
align = HorizontalAlignment.Stretch;
break;
default:
align = HorizontalAlignment.Stretch;
break;
}
return align;
}
public object ConvertBack(object value, Type targetType, object parameter, string language)
{
throw new NotImplementedException();
}
}
And the XAML code:
<Page.Resources>
<local:TransTypeToAlignConverter x:Key="TransTypeToAlign" />
</Page.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<ListView x:Name="myList" Height="Auto" Grid.Row="1">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<Grid Margin="10,0,10,0">
<Rectangle Fill="DarkGray" Width="320" Margin="3,18,0,0" HorizontalAlignment="{Binding transactionType, Converter={StaticResource TransTypeToAlign}}"/>
<StackPanel Width="320" Margin="0,13,3,3" HorizontalAlignment="{Binding transactionType, Converter={StaticResource TransTypeToAlign}}" Background="Gray">
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
As I mentioned, this code is working. But I would like to format other things as well, not the Alignment only. For example I would like a dynamic Stackpanel width, not the fix 320px. For this I should write a code similar to the above. I think it's too much code for a similar thing, and it will be hard to modify later.
I have one value (TransType) which defines the alignment, the stackpanel width, the textblock message, and the color of the text. So, is it possible to make a template for formatting xaml?

A criticism of the pattern comes from MVVM creator John Gossman himself, who points out that the overhead in implementing MVVM is "overkill" for simple UI operations. MVVM Wiki
You can either do it with multiple converters or you can do it with a ItemTemplateSelector, in the latter case you would need to defined each template separately.
