I am trying to fill a generic list the intellisence tells me everything is what it is asking for but it keeps giving me an error
System.Collections.Generic.List<PlmData.POLineData>.List(int)' has some invalid arguments
                int polinekey = Convert.ToInt32(e.Row.Cells["polinekey"].Value);
                PlmData.PO p = new PlmData.PO();
                List<PlmData.POLineData> dd = new List<PlmData.POLineData>(p.GetPODetails(polinekey));               try
                {
                    qcd.custname = dd[0].CustName;
                    qcd.factory = dd[0].Factory;

Youre attempting to stick a PODetailsData object into a list that is expecting PlmData.POLineData objects. Also, the overload you are looking for takes in an array or another list of objects, not a single object, which is what your function returns.

I know you aren't going to be interested but here goes anyway.  I'd suggest you have a look about collections in the help files - specifically about how to use them.  (Obviously you didn't understand the advice given to you in your previous question after all).

Got it
               int polinekey = Convert.ToInt32(e.Row.Cells["polinekey"].Value);
                PlmData.PO p = new PlmData.PO();
                PlmData.PODetailsData dd = new PlmData.PODetailsData();
                dd = p.GetPODetails(polinekey);

POBindingSource.DataSource = DataContext;
DataContext = _detailsData;
int polinekey = Convert.ToInt32(e.Row.Cells["polinekey"].Value);
                PlmData.PO p = new PlmData.PO();
                PlmData.PODetailsData dd = new PlmData.PODetailsData();
                dd = p.GetPODetails(DataContext,polinekey);
