Examples

The following code example demonstrates how to use the GetValues method to get the original values of the Name column in the primary buffer of DataStore.

using System;
using DWNet.Data;
using PowerScript.Bridge;

namespace Appeon.ApiDoc.DataStoreExtensionsExamples
{
    public class GetValuesExample
    {
        private readonly SchoolContext _context;

        public GetValuesExample(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);

            datastore.Retrieve();
            // Modifies the data in the first row
            datastore.SetItem(0, 1, "department name");

            // Gets the original data values in the primary buffer
            var names = datastore.GetValues<string>("Name", DwBuffer.Primary, true);

            Console.WriteLine($"names Length={names.Length}, names[0]={names[0]}");

            /*This code produces the following output:
            
            names Length=4, names[0]=Engineering            
            */
        }
    }
}
