Calculating values on web page in asp.net

Question

I am having a ASP.net web page. It is some sort of order page ...

we have table on that page. the columns are Name of product, unit price, Quantity, Total price of the product. there are multiple products in rows of table

The Quantity column have TextBox for inputting the value.

I have one Calculate button... on clicking that the Total Price column should display the calculated value of products.

on button click all products rows "Total Price" column should display calculated value (Quantity * UnitPrice)

I am not getting how to achieve that, as im new to ASP.NET.

Any Idea ?

what are you using asp.net controls or html controls. for asp.net you can refer using thier name and for html you have to use javascript or jquery for code — Amritpal Singh

retag your question, add some other tags like Javascript if you, as you said, want to use javascript. — Mubarek

@Vijay if you are not constrained with javascript then you should use jquwery that will ease a lot of your work — Amritpal Singh

but if i have to use datagrid now then i have to replace all my Table. Also i have to fill the table partially with the fixed texts and partially with the fields from database... and also after calculation i have to modify the values in particular column cell too. How can i achieve that?

Here's another one that doesn't reach for jQuery.

Have a look at the Repeater control[msdn.microsoft.com/en-us/library/zzx23804(v=vs.85).aspx] or the GridView[msdn.microsoft.com/en-us/library/… control to get your data on to the page.

If you have hard coded your table as your comments suggest then why not just do

int ProductOneTotal = (int)ProductOnePrice.Text * (int)ProductOneAmount.Text;
int ProductTwoTotal = (int)ProductTwoPrice.Text * (int)ProductTwoAmount.Text;

      ...and so on for each product and then.

int ProductTotal = ProductOneTotal + ProductTwoTotal + ....the rest;

Leaving you with ProductTotal which is the total value.
