WPF Trigger based on Object Type

Question

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

Answer 1

This is based on @AndyG's answer but is a bit safer because it's strongly typed.

Implement an IValueConverter named DataTypeConverter, which accepts an object and returns its Type (as a System.Type):

public class DataTypeConverter:IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, 
      CultureInfo culture)
    {
        return value?.GetType() ?? Binding.DoNothing;
    }

    public object ConvertBack(object value, Type targetType, object parameter,
      CultureInfo culture)
    {
       throw new NotImplementedException();
    }
}

Change your DataTrigger to use the Converter, and set the value to the Type:

Declare DataTypeConverter in the resources:
