				?

									<%@ Page Language="C#" %>

									<%@ import Namespace="System.Collections" %>

									<script runat="server">

									void Page_Load(Object sender, EventArgs e) {

									if(!Page.IsPostBack){

									ArrayList data = new ArrayList();

									data.Add(new Person("Tom",33,true));

									data.Add(new Person("Jhon",39,false));

									data.Add(new Person("Mark",20,false));

									data.Add(new Person("Linda",27,true));

									MyDataGrid.DataSource = data;

									MyDataGrid.DataBind();

									}

									}

									void GetValues_Click(Object sender, EventArgs e) {

									String Result = "";

									foreach(DataGridItem dataGridItem in MyDataGrid.Items){

									//Get name from cell[0]

									String Name = dataGridItem.Cells[0].Text;

									//Get text from textbox in cell[1]

									String Age = ((TextBox)dataGridItem.FindControl("AgeField")).Text;

									//Get Checked property of Checkbox control

									bool IsGraduate = ((CheckBox)dataGridItem.FindControl("IsGraduateField")).Checked;

									// get Values from Checkboxlist

									String Skills = "";

									foreach(ListItem item in ((CheckBoxList)dataGridItem.FindControl("CheckBoxList1")).Items){

									if (item.Selected){

									Skills += item.Value + ",";

									}

									}

									Skills = Skills.TrimEnd(',');

									//Get RadioButtonList Selected text

									String Experience = ((RadioButtonList)dataGridItem.FindControl("RadioButtonList1")).SelectedItem.Text;

									//Get DropDownList Selected text

									String Degree = ((DropDownList)dataGridItem.FindControl("DropDownList1")).SelectedItem.Text;

									// Build String to show result.

									Result += Name;

									Result += " [Age -" + Age + "] ";

									if (IsGraduate){

									Result += "Is Graduate , ";

									}else{

									Result += "Is not Graduate , ";

									}

									Result += "Has Skills[" + Skills + "] , ";

									Result += "Has " + Experience + " Experience , And " ;

									Result += "Has " + Degree + " Degree." ;

									Result += "<br>";

									}

									ResultField.Text = Result;

									}

									class Person{

									String _Name;

									int _Age;

									bool _IsGraduate;

									public Person(String name,int age, bool isGraduate){

									_Name = name;

									_Age = age;

									_IsGraduate = isGraduate;

									}

									public String Name{

									get{return _Name;}

									}

									public int Age{

									get{return _Age;}
