Q: 

Winforms BindingSource

I have a binding source object that fills some textboxes. In run time, after editing the textboxes I want to be able to retrieve the old values.

how can I retrieve the Textbox's old value and refresh the screen ? Maybe the binding source has history or something ?!

+1  A: 

No, it does not. Databinding is not about keeping history. You want the original values, keep them outside of your binding source and controls ;) Basic design principle - to keep the whole databinding infrastructure lean. Because in MANY cases the history is not needed, and in the others it is best implemented in the business side, not the databinding.

I have the bounded object kept outside, what Can I do now to Update the controls with the old values ? I don't want to start do that like this : "textbox1.text =..." ,Can I just change the datasource and do somehow Refresh to the screen\Controls ?
