GridView1.DataBind();

int NUM = 0;

foreach (DataRow dr in cart.Rows)

{NUM += int.Parse(dr["NUM"].ToString()) * int.Parse(dr["jiage"].ToString());

}

Label3.Text = NUM.ToString();

十．删除时跳出对话框

双击GridView的OnRowDataBound事件；

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) {

if (e.Row.RowType == DataControlRowType.DataRow)

{

if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)

{

((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除："" + e.Row.Cells[1].Text + ""吗?')");

}

}

}
