怎么实现点击GridView中一个按钮可以获取这一行的数据,控件都是在模板中的

Question

gridview数据

Answer 1

按钮设置命令后，在命令执行的事件中，通过Convert.ToInt32(e.CommandArgumentCo)获取行索引，这样你通过索引就可以访问到数据集中指定索引的row，就可以访问其中各个单元格了

Answer 2

按钮命令是什么..可以详细一点么   哪个事件..  我的按钮都是这个时间下判断的.
 
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        
        if (e.CommandName == "del")
        {
            ppm.DeletePaper(Convert.ToInt32(e.CommandArgument.ToString()));
            this.GridView1.DataSource = ppm.GetPapers();
            this.GridView1.DataBind();
        }
