using System;

namespace Appeon.ApiDoc.IDataStoreExamples
{
    public class SetItemExample
    {
        private SchoolContext _context;

        public SetItemExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example1()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            // Retrieves rows from the database for datastore
            datastore.Retrieve();

            Console.WriteLine("After Retrieve, Rowcount: {0}",
                              datastore.RowCount);

            // Sets the value for column 2 in row 1 to "Engineering New"
            datastore.SetItem(0, 1, "Engineering New");

            Console.WriteLine("Gets the original value of name: {0}",
                datastore.GetItemString(0, 1, DwBuffer.Primary, true));

            Console.WriteLine("Gets the modified value of name: {0}",
                datastore.GetItemString(0, 1, DwBuffer.Primary, false));

            /*This code produces the following output:
            
            After Retrieve, Rowcount: 4   
            Gets the original value of name: Engineering
            Gets the modified value of name: Engineering New
            */
        }
    }
