9.2.2 Custom Sorting Using the IComparer Intece

The following code example demonstrates custom sorting using the Sort(IComparer) overload of the Sort method, which takes an implementation of the IComparer intece to perform a multiple-column sort.

using System;

using System.Drawing;

using System.Windows.Forms;

class Form1 : Form

{

private DataGridView DataGridView1 = new DataGridView();

private FlowLayoutPanel FlowLayoutPanel1 = new FlowLayoutPanel();

private Button Button1 = new Button();

private RadioButton RadioButton1 = new RadioButton();

private RadioButton RadioButton2 = new RadioButton();

// Establish the main entry point for the application.

[STAThreadAttribute()]

public static void Main()

{

Application.Run(new Form1());

}

public Form1()

{

// Initialize the form.

// This code can be replaced with designer generated code.

AutoSize = true;

Text = "DataGridView IComparer sort demo";

FlowLayoutPanel1.FlowDirection = FlowDirection.TopDown;
