推荐答案

尝试以下代码:

try this code:

public void totalprice()
   {
       float pricee;
       int quantityy;
      float totalprice;
       foreach (GridViewRow row in GridView1.Rows)
       {
           int pro_id = Convert.ToInt32(GridView1.DataKeys[row.RowIndex][0]);
           pricee = dal.getprice(pro_id);
           quantityy = dal.getquantity(pro_id);
           totalprice += quantityy * pricee;
       }
      lbltprice.Text = totalprice.ToString();
   }

// this is a javascript code used to retrieve gridview row value
function Read_Data()
{
    var str=0;
    // here grid_list is the id of your asp.net gridview
    // grid_list.ClientID gives asp.net server executed id of the gridview
    // inside the for loop cells[3] which denote 3 column from the gridview
    // str is a variable which will sum up all your row values on the column
    var Grid_Table = document.getElementById('<%=grid_list.ClientID%>');
    for(var row=1; row<Grid_Table.rows.length; row++)
    {
                    if(document.all)
                        str=str+Number(Grid_Table.rows[row].cells[3].innerText);

                    else
                        str=str+Number(Grid_Table.rows[row].cells[3].textContent);

    }
    alert(str);
    return false;
