Binding to an anonymous type

Try to imagine that you have a list of complex classes and you just want to display just a bunch of properties.
For example:
Person.Firstname,
Person.Lastname,
Person.Address.District.Name,
Person.Cars[0].Brand,
Person.Cars[1].Brand
I was playing around with ValueConverter and found out, that i can return an anonymous type out of the converter and bind it to a textblock’s content.
public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (value is Persons) { var persons = (Persons)value; var query = from person in persons let firstname = person.Firstname let lastname = person.Lastname let districtname = person.Address.District.Name let car1 = person.Cars[0].Brand let car2 = person.Cars[1].Brand select new { Firstname = firstname, Lastname = lastname, Districtname = districtname, Car1 = car1, Car2 = car2 }; return query; } return value; } |
Updating the values as you maybe guess don’t work, but if you dont want to write complex bindings you can use this technique to archive the result.
