Hi guys, i am totally new to asp.net or C#.. In a page i need to have a gridview, which at start will contain a single row. there are 3 columns (2 textbox and 1 label).
one of these textbox has autocomplete feature, so whn i write a item name in that textbox and in the other textbox put a quantity, i need to display the item's price from database * the quantity in the label. also i need to add another row and do the similar for that row also. at the end i need to display the sum of all the amounts that has been displayed in each rows in a label outside the gridview.

Do you have a specific programming question? Everything you wrote is quite a bit of explanation that probably could not be easily answered in a forum post.

If you're 'totally new' to both, then this is an insane task for you. You should learn C#, then if you already know HTML and SQL, learn ASP.NET. You've spent a week trying to solve a specific task ? It would go faster if you broke it down in to component steps and worked out how to do those. I hope no-one is waiting for you to complete this, if you spent a week trying to work out how to do one task ?
