Get GridViewRow from Autopostback control event

Sometime we have checkbox control or other control inside gridview.
We need to do when checkbox clicked then some action affected to that row, for example getting datakey, rowindex or getting cell value.

ASPX

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

This sample code is getting gridviewrow from checkbox checked changed event then displaying value from another cell to a label.

C#

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
  GridViewRow gvrow = ((Control)sender).Parent.Parent as GridViewRow;
  Label1.Text = gvrow.Cells[2].Text;
}

Using Naming Container

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
  {
        GridViewRow row=(GridViewRow)(((CheckBox)sender).NamingContainer);

  }
