You shouldn't have to do anything, if you've databound them with the same syntax ... a common mistake that a lot of people make. Let me explain:

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. BTW, I prefer the second binding syntax.

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")

// And your CurrencyManager/BindingContext would be:
CurrencyManager cm = (CurrencyManager)this.BindingContext[MyDataSet, "MyTable"];

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")

// And your CurrencyManager/BindingContext would be:
CurrencyManager cm = (CurrencyManager)this.BindingContext[MyDataSet.Tables["MyTable"]];
