            <ItemTemplate>
                <asp:CheckBox ID="CheckBox1" runat="server" oncheckedchanged="CheckBox1_CheckedChanged" AutoPostBack="true" />

public partial class Default14 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack == true)
            return;
        DataTable dtTemp = new DataTable();
        dtTemp.Columns.Add("Student ID");
        dtTemp.Columns.Add("First Name");
        dtTemp.Columns.Add("Last Name");
        dtTemp.Rows.Add("1", "Peter", "Leow");
        dtTemp.Rows.Add("2", "James", "Song");
        dtTemp.Rows.Add("3", "Mick", "Sam");
        dtTemp.Rows.Add("4", "MAry", "Cool");
        GridView1.DataSource = dtTemp;
        GridView1.DataBind(); 
    }

    protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chk = (CheckBox)sender;
        TextBox1.Text = "";
        foreach (GridViewRow row in GridView1.Rows)
        {
            CheckBox chkBox = (CheckBox)row.FindControl("CheckBox1");
            if (chkBox != null && chkBox.Checked)
            {
                TextBox1.Text += " " + row.Cells[1].Text.ToString() + " " + row.Cells[2].Text.ToString() + " " + row.Cells[3].Text.ToString();
