The following code example demonstrates that the UpdateEnd event is triggered when update finished in the DataStore.

using DWNet.Data;
using System;

namespace Appeon.ApiDoc.IDataStoreBaseExamples
{
    public class UpdateEndExample
    {
        private SchoolContext _context;

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

        public void Example()
        {
            // Instantiates datastore with datawindow: d_department
            var department = new DataStore("d_department", _context);

            // Inserts a department record.
            decimal id = 1;
            var insertRow = department.InsertRow(0);

            department.SetItem(insertRow, "Departmentid", 10);
            department.SetItem(insertRow, "Name", "test depart");
            department.SetItem(insertRow, "Budget", id);
            department.SetItem(insertRow, "Startdate", DateTime.Parse("2018-12-12"));

            // Defines what to do after Update completes.
            department.UpdateEnd +=
                (object sender, DwUpdateEventArgs args) =>
                {
                    Console.WriteLine("{0} records have been updated into the database.",
                                       args.RowsInserted);
                };

            department.Update();

            /*This code produces the following output:
            
             1 records have been updated into the database.
            */

        }
