Hi,

I am not sure where best to ask this, but i'm developing a custom order form for a project, a Datagrid (for each category) then has a gridview inside it, with the products in that category, the gridview has columns: Product, Price, Quantity, Total. I need to have it so that when they enter a quantity, the total (column 2 x column 3) is calculated, autopostback isn't an option as the order form and the code that drives it is quite extensive, and reload times are too long.

Additionally at the bottom of each category, i'd like to 'total the total columns', and show a grand total at the very bottom, all without postback.

I assume i'll need to incorporate javascript somehow, or can it be done somehow without javascript - Ajax isn't an option for me either:(

If java is the option, does anyone have a small example of how i might achieve this?

Hoping for an answer, and thanks :)
