Sorting with DataGridView using C#.

Introduction

In this article I m going to discuss how to use DataGridView in window form and how to bind data from the XML file.

Here I am using the following XML file. This file contains the record of some books.

<?xml version="1.0" encoding="utf-8" ?>
<bookstore>
    <book>
        <SrNumber>1</SrNumber>
        <Title>ASP.NET 2.0</Title>

Now lets start how to use DataGridView. Simply open Visual Studio clik on File -> New -> Project and drag a DataGridView control from the toolbar on the form like as follows.

Figure 1. DataGridView control on Window Form.

I also put four buttons to perform sorting by various types. Now I m writing C# code to binding the data and perform the sorting. On the form load dataGridView is binding. And on button click you can see the code of sorting.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
using System.Xml;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            XmlDataDocument xmlDatadoc = new XmlDataDocument();
            xmlDatadoc.DataSet.ReadXml("C:\\books.xml");

            DataSet ds = new DataSet("Books DataSet");
            ds = xmlDatadoc.DataSet;

            dataGridView1.DataSource = ds.DefaultViewManager;
            dataGridView1.DataMember = "Book";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            XmlDataDocument xmlDatadoc = new XmlDataDocument();
            xmlDatadoc.DataSet.ReadXml("C:\\books.xml");

            DataSet ds = new DataSet("Books DataSet");
            ds = xmlDatadoc.DataSet;

            DataView myDataView = ds.Tables[0].DefaultView;
            myDataView.Sort = "title ASC";

            dataGridView1.DataSource = myDataView;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            XmlDataDocument xmlDatadoc = new XmlDataDocument();
            xmlDatadoc.DataSet.ReadXml("C:\\books.xml");

            DataSet ds = new DataSet("Books DataSet");
            ds = xmlDatadoc.DataSet;

            DataView myDataView = ds.Tables[0].DefaultView;
            myDataView.Sort = "PublicationYear ASC";

            dataGridView1.DataSource = myDataView;
        }

        private void button3_Click(object sender, EventArgs e)
        {
            XmlDataDocument xmlDatadoc = new XmlDataDocument();
            xmlDatadoc.DataSet.ReadXml("C:\\books.xml");

            DataSet ds = new DataSet("Books DataSet");
            ds = xmlDatadoc.DataSet;

            DataView myDataView = ds.Tables[0].DefaultView;
            myDataView.Sort = "Price ASC";

            dataGridView1.DataSource = myDataView;
        }

        private void button4_Click(object sender, EventArgs e)
        {
            XmlDataDocument xmlDatadoc = new XmlDataDocument();
            xmlDatadoc.DataSet.ReadXml("C:\\books.xml");

            DataSet ds = new DataSet("Books DataSet");
            ds = xmlDatadoc.DataSet;

            DataView myDataView = ds.Tables[0].DefaultView;
            myDataView.Sort = "Author ASC";

            dataGridView1.DataSource = myDataView;
        }
    }
}

Output

Now debug the application and you will get the following output.
