Textbox Controls and data display

Hello All,
Am using textbox to display details of customers like customerID, companyname, contactname, address, city, region, country, phone in a aspx page from the ms access database. My question is Is it possible to update and delete data in the textbox. Also i have used next, previous button in the same page to navigate through the data. when ever i press next button it displays first and second data only. Beyond that it doesnt display even though there are 91 records in the database. how to solve it. When i press last it shows last record but when i press previous button it directly displays the first record when it has to display the previous record when i am viewing the last record. How to resolve this. Please help me with these.

Thanks in advance,

Avinash
