Add row to data bound form

[Paul]

I have a data bound form to which I wish to add a new row
of data using c#. (SQL Server database accessed with
Stored Procedures using SQLClient)

If I try to add a new row for a user, I can add a new row
using code like this.

DataRow newRow =
this.dsetContract.dcl_fsubContractDelivery.NewRow( );
newRow["ContractID"] = this.ContractID;
newRow["MonthNo"] = System.DBNull.Value;
this.dsetContract.dcl_fsubContractDelivery.Rows.Ad d
(newRow);
this.dsetContract.dcl_fsubContractDelivery.Rows[
this.dsetContract.dcl_fsubContractDelivery.Rows.Co unt -
1].EndEdit();
this.BindingContext
[this.dsetContract.dcl_fsubContractDelivery].Position
=
this.frmCaller.dsetContract.dcl_fsubContractDelive ry.Count
- 1;
The new row is added to the datatable which I have checked
by running a count on the datatable and can access values
using code, but I cannot get the Position of the
BindingContext to go to the new row. I have tried with and
without the EndEdit() command.

This is confusing me so any help would be appreciated.
