如何使用

后面的代码在网格视图页脚中显示多行信息

例如

protected void gridinvoice_RowDataBound(object sender, GridViewRowEventArgs e)
{
    decimal Amount = 0;

    for (int y = 0; y < gridinvoice.Rows.Count; y++)
    {
        Amount += Convert.ToDecimal(gridinvoice.Rows[y].Cells[4].Text);
    }

    if (e.Row.RowType == DataControlRowType.Footer)
    {  
        e.Row.Cells[3].Text = "Amount";
        e.Row.Cells[4].Text = Amount.ToString();
    }

}

如何在页脚中添加运费和总金额

def get_host_regex(self, spider):
    """Override this method to implement a different offsite policy"""
    allowed_domains = getattr(spider, 'allowed_domains', None)
    if not allowed_domains:
        return re.compile('') # allow all by default
    regex = r'^(.*\.)?(%s)$' % '|'.join(re.escape(d) for d in allowed_domains if d is not None)
    return re.compile(regex)

def spider_opened(self, spider):
        self.host_regex = self.get_host_regex(spider)
        self.domains_seen = set()

根据您的要求，您可以尝试这样：

protected void gridinvoice_RowDataBound(object sender, GridViewRowEventArgs e)
{
    decimal Amount = 0;

    for (int y = 0; y < gridinvoice.Rows.Count; y++)
    {
        Amount += Convert.ToDecimal(gridinvoice.Rows[y].Cells[4].Text);
    }

    if (e.Row.RowType == DataControlRowType.Footer)
    {  
        e.Row.Cells[3].Text = "Amount: <br/> Shipping Cost: <br/> Total Amount:";
        e.Row.Cells[4].Text = Amount.ToString() +"<br/>"+shipping.ToString() +"<br/>" + total.ToString();
    }

}

或者您可以使用控件和页脚模板在Aspx页面上构建页脚，并将值分配给后面代码的控件。

  protected void gridinvoice_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        decimal Amount = 0;

        for (int y = 0; y < gridinvoice.Rows.Count; y++)
        {
            Amount += Convert.ToDecimal(gridinvoice.Rows[y].Cells[4].Text);
        }

        if (e.Row.RowType == DataControlRowType.Footer)
        {  
           Label lblamount = e.Row.FindControl("lblid") as Label;
           lblam.Text = Amount.ToString();
        }

    }
