Hello i have a List of this custom class of mine (List<ClassePerLifoFifoGestioneInner>).
The class i built like this:
public class ClassePerLifoFifoGestioneInner
{
public int Artico01S00_LifoFifo_NrMag { get; set; }
public string Artico01S00_LifoFifo_CodiceArticolo { get; set; }
public decimal Artico01S00_LifoFifo_Anno_Formazione { get; set; }
public short Artico01S00_Stato { get; set; }
public string Artico01S00_Categoria { get; set; }
public string Artico01S00_SubCategoria { get; set; }
public string Artico01S00_Famiglia { get; set; }
public string Artico01S00_Sub_Famiglia { get; set; }
}
I have a windows form, with some lookupedits, textboxes, calcEdits etc; where I input or choose some values in and when i press a button to search in the list that i have i would like to filter it with those values directly in the where in a way that's dynamically created without having to hardcode the lambda expression directly in to the code.
Example: If I enter NrMag = 1 and CodiceArticolo = 00024005 on my form. I want to filter my List like this: LstCurrClassePerGestioneDettaglio.Where(x => x.Artico01S00_LifoFifo_NrMag == NrMag && x.Artico01S00_LifoFifo_CodiceArticolo == CodiceArticolo) in a way that is dyanamic, based on how many values(lookupedits, calcEdits, textboxes) I input in the form.
Another example would be: I entered NrMag = 1, CodiceArticolo = 00024005, Stato = true; LstCurrClassePerGestioneDettaglio.Where(x => x.Artico01S00_LifoFifo_NrMag == NrMag && x.Artico01S00_LifoFifo_CodiceArticolo == CodiceArticolo && x.Artico01S00_Stato == Stato);
The final goal is to have this expression dynamically created and slam it in to the Where of my query.
var expression = MethodThatIdontKnowHowToCreate();
LstCurrClassePerGestioneDettaglio = LstCurrClassePerGestioneDettaglio.Where(expression).ToList();
So i can fill my GridControl DataSource.
gcArtico01S00_LifoFifoGestione.DataSource = LstCurrClassePerGestioneDettaglio;
