your question is not so clear...Do you want to calculate the value out the Grid view if the Quantity changes dynamically?

this code execute partially...

public void totalprice()
{
float pricee;
int quantityy;
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);

Instead of adding total price in code behind you can give like this

SQL

CREATE TABLE ItemList
(
[ItemID] int primary key identity(1,1),
[ItemName] varchar(20),
[ItemPrice] float,
[ItemQuantity] int,
[ItemRate] AS ([ItemPrice]*[ItemQuantity])
)

here I have used calculated column([ItemRate]) for ItemList..u simply call and bind this table using grid view

ASP.NET

<div>
       <asp:gridview id="GridView1" runat="server" autogeneratecolumns="False" xmlns:asp="#unknown">
           AutoGenerateEditButton="True" DataKeyNames="ItemID"
           DataSourceID="ProductDataSource">
           <columns>
               <asp:boundfield datafield="ItemID" headertext="ItemID" insertvisible="False">
                   ReadOnly="True" SortExpression="ItemID" />
               <asp:boundfield datafield="ItemName" headertext="ItemName">
                   SortExpression="ItemName" />
               <asp:boundfield datafield="ItemPrice" headertext="ItemPrice">
                   SortExpression="ItemPrice" />
               <asp:boundfield datafield="ItemQuantity" headertext="ItemQuantity">
                   SortExpression="ItemQuantity" />
               <asp:boundfield datafield="ItemRate" headertext="ItemRate" readonly="True">
                   SortExpression="ItemRate" />
           </asp:boundfield></asp:boundfield></asp:boundfield></asp:boundfield></asp:boundfield></columns>
       </asp:gridview>

       <asp:sqldatasource id="ProductDataSource" runat="server" xmlns:asp="#unknown">
           ConnectionString="<%$ ConnectionStrings:PurchaseMasterConnectionString %>"
           SelectCommand="SELECT * FROM [ItemList]"
           UpdateCommand="Update [ItemList] set ItemQuantity=@ItemQuantity where ItemID=@ItemID "></asp:sqldatasource>

   </div>

now click edit in grid change u r quantity value click update now rate will be updated automatically
