You have to use DataBinding. Get the data you want to show in textBoxes in the dataTable, then set data binding for each textBox and use "CurrencyManager".

this is the complete coding am using upto this everything working just tell me acc to my code what i have to do for NEXT and PREVIOUS BUTTIN coding thanks..

Hmmm, you didn`t study that link at all. I can see that from your code.
I cannot do all the code instead of you.
Please as I told you, read all whats there on that website.

Some way points: you have to get the data from databse into DATATABLE (not directly into textboxes).
Use connection and dataAdapter classes to fill dataTable, the follow the steps from that website (you have to use controls databinding, and CurrencyManager class on those two buttons forward and backward).

// Position to prev Record in Customer

        }

yes this thing i know but where i can define current manager and binding text?

As I see from you code, you are doing .NET application (web application).
So CurrencyManager is out of question. It is only available in win forms. Win forms and Asp.net applications are two completel different things.
Iam not very familiar with asp.net programming (yet), so I cannot help you out here. Sorry. But you can take a look at here, or ask a question to some Asp.NET forum.
I hope you manage to work it out.
