Answer 1

<asp:GridView ID="GridView1" AutoGenerateColumns="False" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowCommand = "OnRowCommand">

Use

OnRowCommand = "OnRowCommand"

Now when any action happen on the grid the OnRowCommand event is executed.

protected void OnRowCommand(object sender, GridViewCommandEventArgs e)
{
    int index = Convert.ToInt32(e.CommandArgument);
    GridViewRow gvRow = GridView1.Rows[index]; 
}

Answer 2

<ItemTemplate>
    <asp:Button ID="Button1" runat="server" Text="Button" 
            OnClick="MyButtonClick" />
</ItemTemplate>

and your method

protected void MyButtonClick(object sender, System.EventArgs e)
{
    //Get the button that raised the event
    Button btn = (Button)sender;

    //Get the row that contains this button
    GridViewRow gvr = (GridViewRow)btn.NamingContainer;

}
