The following code example shows how to use the Clear method to clear data from all buffers.

using Appeon.ApiDoc.Models;
using DWNet.Data;
using System;

namespace Appeon.ApiDoc.IDataStore_GenericExamples
{
    public class ClearExample
    {
        private readonly SchoolContext _context;

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

        public void Example()
        {
            // Instantiates a DataStore object with datawindow object: d_department.
            var datastore = new DataStore<D_Department>(_context);

            datastore.Retrieve();
			
			// Removes the first row from the DataStore.
            datastore.RemoveAt(0);
			
			// Sets the Name column in the first row to Engineering New.
            datastore.SetItem(0, "Name", "Engineering New");
			
			// Filters rows by the filter criterion (Name = Engineering New).
            datastore.Filter(a => a.Name.Equals("Engineering New"));

            // Clears data from all buffers
            datastore.Clear();

            Console.WriteLine("TotalCount: {0}", datastore.TotalCount);
            Console.WriteLine("DeletedCount: {0}", datastore.DeletedCount);
            Console.WriteLine("FilteredCount: {0}", datastore.FilteredCount);
            Console.WriteLine("ModifiedCount: {0}", datastore.ModifiedCount);

            /*This code produces the following output:
            
            TotalCount: 0
            DeletedCount: 0
            FilteredCount: 0
            ModifiedCount: 0
            */
