I'm working on a WinForm application of VB.NET 4.0 

I bind a MySetting property to a TextBox it runs ok until I change the value in the TextBox; the program keep reading the old value even if I do a reload before read.

I remember that is not need to update save or reload, because I made another WinForm application and the value is update without the need of add any code by me.

When the value is updated in MySetting after I change the value in the TextBox? When the TextBox lost focus?
