GridView 中RowCommand事件用法

GridView 中RowCommand事件用法
//如果我照提示说的把enableEventValidation的值设为False,就获取不到e.CommandArgument的值.
    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {

        if (e.CommandName == "Del")
        {
            
            Response.Write("删除");

            GridViewRow row = (GridViewRow)((Control)e.CommandSource).Parent.Parent;

            string index = row.Cells[3].Text;//当前行第一个单元格的值

          
            object myCommandArgument = e.CommandArgument;
            
            Response.Write(myCommandArgument);

            Response.Write(index);

        }

        if (e.CommandName == "Upd")
        {
            
            Response.Write("修改");

            string dw = e.CommandArgument.ToString();

            for (int i = 0; i < GridView1.Rows.Count; i++)
            {
                string id = Convert.ToString(GridView1.Rows.Cells[0].Text);

                if (id == dw)
                {
                    Response.Write(id);

                }

            }
          
        }

    }
