Examples

The following code example demonstrates how to use the GetNextModified method to get the row number of the modified row in the primary buffer.

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

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

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

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

            // Modifies the data of 2nd column in 2nd row
            datastore.SetItem(1, 1, "department name");

            // Gets the row number of the modified row in the DataStore.
            int row = datastore.GetNextModified(-1, DwBuffer.Primary);

            Console.WriteLine($"row={row}");

            /*This code produces the following output:
            
            row=1           
            */
        }
    }
}
