Question

Hello got typed Dataset named DSMain.

Tables

User:
U_id int
U_fname string
U_lname string U_Case int

Case:
C_id int C_date string C_status int

U_Case is in relation with C_Status,

I want to add data to this table.

public static void
AddNewDluznik(string fname, string
lname, int case)
{
MainData.User.AddUserRow(fname, lname,
case);
}

Without rel it works.

Argument ‘3’: cannot convert from ‘int’ to ‘Zefir.DSMain.CaseRow’.

Answer 1

The way you are doing it, AddUserRow has the following signature:

AddUserRow(string fName, string lName, CaseRow case) //note case is of type CaseRow, not int.

You need to reference the CaseRow in your Case table to which your user is referencing:

public static void AddNewDluznik(string fName, string lName, int case)
{
    MainData.User.AddUserRow(fName, lName, MainData.Case.FindByC_id(case));
}

Alternatively, if you are working with isolated tables, and not the whole DataSet you can:

public static void AddNewDluznik(string fName, string lName, int case)
{
     var row = MainData.User.NewUserRow();
     row.U_fname = fName;
     row.U_lname = lName;
     row.U_Case = case; 
     MainData.User.AddUserRow(row);
}
