Problem with Create([Bind

Hi,

I use asp net core mvc (2.0)

I have three tables which have relations:

CREATE TABLE [dbo].[ProdukteArtikel] (
    [ID]		INT            IDENTITY (1, 1) NOT NULL,
    [Price]		DECIMAL (18, 2)          NULL,
    ...
CONSTRAINT [PK_ProdukteArtikel] PRIMARY KEY CLUSTERED ([ID] ASC)
);



CREATE TABLE [dbo].[Produkte] (
	[ID]			INT             IDENTITY (1, 1) NOT NULL,
	...
CONSTRAINT [PK_Produkte] PRIMARY KEY CLUSTERED ([ID] ASC)
);



CREATE TABLE [dbo].[ProdukteArtikelRelation] (
	[ID]			INT		IDENTITY (1, 1) NOT NULL,
	[Produkt]		INT		NULL,
	[ProduktArtikel]	INT		NULL,
	[Piece]			INT		NULL,
	[Price]			DECIMAL (18, 2)	NULL,
	[Total]			DECIMAL (18, 2)	NULL,
CONSTRAINT [PK_ProdukteArtikelRelation] PRIMARY KEY CLUSTERED ([ID] ASC),
CONSTRAINT [FK_ProdukteArtikelRelation_ProdukteArtikel] FOREIGN KEY ([ProduktArtikel]) REFERENCES [dbo].[ProdukteArtikel] ([ID]),
CONSTRAINT [FK_ProdukteArtikelRelation_Produkte] FOREIGN KEY ([Produkt]) REFERENCES [dbo].[Produkte] ([ID])
);

In View/ProdukteArtikelRelation/Create I write Data to dbo.ProdukteArtikelRelation.
There I have only 3 Fields: "Produkt", "ProduktArtikel" and "Piece".
"Produkt" and "ProduktArtikel" are SelectLists. For "Piece" there is a entry field.

My "ProdukteArtikelRelation" Controller looks like:

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("Id,Produkt,ProduktArtikel,Piece,Price,Total")] ProdukteArtikelRelation produkteArtikelRelation)

Is there a possibility to read the "Price" from "ProdukteArtikel", make a short calculation and store these values in "Price" and "Total"?

Thanks
