Dynamic datagrid's headers and binding

The problem:

I have a list of objects which have Date, Name, and Value Properties. Name and Date properties could be different or the same.

orange  2012-01-01  1
orange  2013-01-01  0

I'd like create a GridView with Headers (which are distinct dates) and rows 

  Name   2012-01-01   2013-01-01
orange       1            0

As you see objects do not have properties like '2012-01-01', so simple binding will not help.

Question

How can I create a binding using column's name?

This I'd like to do with XAML or converters, without using UserControl's events

Essentially what you need to do (as you've noticed) is create a list of objects with dynamic properties (that is, properties populated at runtime). The transformation itself is a pivot on Date, with a sum (?) across value, which you can perform using a GroupBy Linq query in your converter.

Now for the tricky part. Take a look at this answer:

Data binding dynamic data

You need to implement ICustomTypeDescriptor to implement dynamic properties. Good luck.

take your list of objects - create a new list of objects with your conditions. then simply put the new list as itemssource to a datagrid/itemscontrol.
