I am creating a row in a datagridview in code. Here is the relevant snippet.

DataRowView newRow=(DataRowView)fKPurchaseOrderDetailPurchaseOrderBindingSource.AddNew();

newRow["Customer"] = this.Customer;
newRow["Purchase_Order_No"] = this.PO;
newRow["Production_No"] = calcNewProdNo();
newRow["ProductionNoDueDate"] = nDTPDueDate.Value;
newRow["sType"] = sTypeTextBox.Text;
newRow["Plant"] = "1812"; //THIS DOES NOT WORK
