Hello.
I have connected textbox by databinding to a BindingSource object (to a
specific column of a specific table).

Everything is fine ...
But what if I want to undo the change I have made by the textbox.
(It may be a textbox or any other binded control).
How can I do that ?

Thanks :)

Use instead of Add, Remove (or clear it what mostly is the most simple)

I don't understand.
What this is related to undo my changes (of only field of the table).

Thanks :)

Textbox1.DataBindings.Clear
Textbox1.DataBindings.RemoveAt(0)
Textbox1.DataBindings.Remove(Textbox.Datatindings(0))

Just call reject changes on the dataset , datatable or datarow ( what is
apropriate in your situation )
http://msdn.microsoft.com/en-us/library/afybt7wb.aspx

the datasource will through the bindingsource reflect the old values to the
screen
