WPF Trigger based on Object Type

Question

Is there a way to do a comparison on object type for a trigger?

Answer 1

Why not just use a converter that takes an object and returns a string of the object type?

Binding="{Binding SelectedItem, Converter={StaticResource ObjectToTypeString}}"

and define the converter as:

public class ObjectToTypeStringConverter : IValueConverter
{
    public object Convert(
     object value, Type targetType,
     object parameter, System.Globalization.CultureInfo culture)
    {
        return value.GetType().Name;            
    }

    public object ConvertBack(
     object value, Type targetType,
     object parameter, System.Globalization.CultureInfo culture)
    {
        // I don't think you'll need this
        throw new Exception("Can't convert back");
    }
}

You'll need to declare the static resource somewhere in your xaml:

Where 'convs' in this case is the namespace of where the converter is.

Hope this helps.
