Examples

The following code example demonstrates how to use the TotalCount property to get the total number of the rows in all buffers of the DataStore after filtering data by the criterion (Budget >= 200000) and deleting data from the DataStore.

using DWNet.Data;
using System;

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

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

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

            datastore.Retrieve();

            Console.WriteLine("Retrieved Totalcount: {0}",
                datastore.TotalCount);

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

            // Filters data that do not meet criteria 'Budget >= 200000'
            datastore.SetFilter("Budget >= 200000");
            datastore.Filter();

            Console.WriteLine("After filtered, Totalcount: {0}",
                datastore.TotalCount);

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

            // Deletes the first row in the DataStore
            datastore.DeleteRow(0);

            Console.WriteLine("After deleted, Totalcount: {0}",
                datastore.TotalCount);

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

            /*This code produces the following output:
            
            Retrieved Totalcount: 4
            Retrieved Rowcount: 4
            After filtered, Totalcount: 4
            After filtered, Rowcount: 3
            After deleted, Totalcount: 4
            After deleted, Rowcount: 2
            */
        }
    }
}
