C # refreshing text field from BindingSource

Question

I'm having difficulty updating Windows stationery controls that use the BindingSource object. We have a CAB / MVP / SCSF client that I (actually "we", as this is a team) are developing that will interact with WCF services running on a remote server. (This is our first attempt, so we are in training mode). One of the calls (from Presenter) to the service returns a DataSet, which contains 3 DataTables called "Contract", "Credit" and "Conditions". Each table contains only one row. When a service returns a dataset, we store it in SmartPart / View in a member variable of the class by calling a function in the BindData () view and passing the dataset to the view from the presenter class;

private System.Data.DataSet _ds = null;
public void BindData(System.Data.DataSet ds)
{
    string sErr = "";
    try
    {
        _ds = ds;  // save to private member variable

        // more code goes down here
    }
}

DataTables Windows Forms TextBoxes, MaskedEditBoxes Infragistics UltraComboEditor. BindingSource, DataTable, VS2008.

private System.Windows.Forms.BindingSource bindsrcContract;
private System.Windows.Forms.BindingSource bindsrcLoan;
private System.Windows.Forms.BindingSource bindsrcTerms;

,

if (bindsrcContract.DataSource == null)
{
    bindsrcContract.DataSource = _ds;
    bindsrcContract.DataMember = "contract";

    txtContract.DataBindings.Add(new Binding("Text", bindsrcContract, "contract_id", true));                       

    txtLateFeeAmt.DataBindings.Add(new Binding("Text", bindsrcContract, "fee_code", true));

    txtPrePayPenalty.DataBindings.Add(new Binding("Text", bindsrcContract, "prepay_penalty", true));

    txtLateFeeDays.DataBindings.Add(new Binding("Text", bindsrcContract, "late_days", true));
}

if (bindsrcLoan.DataSource == null)
{
    bindsrcLoan.DataSource = _ds;
    bindsrcLoan.DataMember = "loan";

    mskRecvDate.DataBindings.Add(new Binding("Text", bindsrcLoan, "receive_date", true));

    cmboDocsRcvd.DataBindings.Add(new Binding("Value", bindsrcLoan, "docs", true));     
}

:

bindingsource.EndEdit() // writting data to underlying source 
bindingSource.ResetBindings(false)  // force controls to reread data from bindingSource
