DataBinding problem

[MaxZak]

I have some problems with databindings in textboxes:
- I've bound the "Text" property to a specific field of a dataTable, and I'm
able to read the correct calue
- When I change the value from the UI, I'm able to save the DataRow (with
"AcceptChanges")
- When I change the "Text" property from code, the field isn't saved (it
saves all the fields that have been modified from the UI or that have
received the focus, but there is no code in the "Validating", "Validated",
etc. events)

Do I have to modify the datarow instead of the "Text" property?
Isn't it the same as typing into the textbox?

Thanks
Max
