Answer 1

document获取单价和数量 然后相乘

编辑按钮会加入,但是编辑了数量,价格还是没变.
另外问问...document是啥...

Answer 6

这是repeater的你可以参考一下foreach (Control c in this.rp.Controls)
        {
            txtAcount = c.FindControl("txtAcount") as TextBox;
           
            if (txtAcount!=null)
            {
                countt = txtAcount.Text;
              if (Comment.IsNumber(countt)==false)
              {
                  return;
                
              }
            }
        }
