	 //数据绑定后触发
	 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
	 {
	 //如果行的类型是数据绑定行
	 if (e.Row.RowType == DataControlRowType.DataRow)
	 {
	 //行的状态是：正常状态 或者 交替行
	 if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
	 {
	 Label lblSex = e.Row.FindControl("lblSex") as Label;
