Question

In this Why Properties Matter article, I found the following:

Properties are used for data binding; fields aren’t.

I would like to know meaning of it. Can someone please elaborate it?

Answer 1

When you data bind a control, only the properties defined on the class you are binding can be used.

So, if your class looks like this:

public class MyClass
{
  public string aField = "something";

  public string aProperty { get; set;}

}

If you use data binding, you can use aProperty as a bound value, but not aField.
