GridView项模版的按钮事件获取该按钮所在行数据

GridView的模版列中加入按钮，触发按钮事件后，如何获取该行的某个值？

<asp:TemplateField HeaderText="ResetPassword">
       <ItemTemplate>
            <asp:Button ID="ResetBtn" runat="server" CssClass="ButtonInGridView" 
                    Text="Reset" onclick="ResetBtn_Click" />
       </ItemTemplate>
</asp:TemplateField>

protected void ResetBtn_Click(object sender, EventArgs e)
{
        Button btn = sender as Button;
        GridViewRow row = (GridViewRow)btn.NamingContainer;

this.NameLbl.Text = row.Cells[0].Text;
}
