I have a list which is created using Binding. I have created a demo project to explain my problem better.
Now I want to update only one item in this list, based on another item. So for example: I want to update the value "Text2", then the code should now that Text1 and Text2 are a pair, so that it knows which value needs to be updated.
I hope it clear what I mean...
The demo project can be found in the attachment.
