Sergio,

Here's the issue:

There are two ways (two different syntaxes) to specify databinding for any control and this results in two distinct binding objects. The problem is that you can't mix and match ... you have to stay consistent throughout the form (and, to be honest, I've found that the first method doesn't always seem to work correctly ... at least in the 1.1 Framework ... maybe it's better in the 2.0 Framework. I always use the second).

So, in other words, if you bound your DataGrid with:

this.oGrid.DataSource = MyDataSet;
this.oGrid.DataMember = "MyTable";

Then you have to use the following syntax with TextBoxes:

this.txtLastName.DataBindings.Add("Text", MyDataSet, "MyTable.LastName")

But if you bound your grid with:

this.oGrid.DataSource = MyDataSet.Tables["MyTable"];

Then you use this syntax for TextBoxes:

this.txtLastName.DataBindings.Add("Text", MyDataSet.Tables["MyTable"], "LastName")

Now, you *were* consistent in your databindings, so that's fine. However, because you used the first syntax, then the syntax for the BindingContext has to correspond. So, it would be this instead:

this.BindingContext[this.grdPolicyChangesNotes.DataSource, "PolicyNotes"].Position = dsPolicyNotes.Tables["PolicyNotes"].Rows.Count - 1;

That should do the trick ... lemme know.
