Datagrid binding and editing

I have a datagrid that is bound at design time in an ASP.NET form. I have five columns in the datagrid that are text boxes. I want to pull values from these five text boxes and use them as parameters in stored procedures. However, when run it in debug mode and I edit one of the text boxes (change the value from a 1 to a 2) and step through the code the value it shows is the original 1, not the 2 that I just entered. Is this a "feature" of databinding? Any help would be appreciated.

I'm going to save it hasn't been stored in the db yet so it hasn't actually changed. But, I don't really know.
