I have an ASP pg with a formview list control on it that hooks up to a sql database customer table
I want to access the customer name outside the form.
How do I:
A) access the bound text box in the form view template? Something like Text1.text=formview1.customername.text (that doesn't work but that's the kinda thing)
B) access the database field in the table that the sqlsource connects to to feed the formview
Really appreciate the help. I bet it's easy to do but I'm just not getting there.
I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?

Code:

I am new to ASP.NET. I have encountered a problem in navigating the database records that is displayed in the web form , the Next and Previous buttons. I have 4 imageboxes and 2 textboxes under each image box for displaying database records.
I am currently using an Access database with a table "Images" and there are 4 columns in it. "ImageID", "ImageDescription","ImageofPicture","Description".
My Code is below:

Im using Visual Web Developer 2010 Express and have put together a custom form using ASP controls and labels.
I now need to update an access database with the data that is captured on the form. I have added an AccessDataSource but do not know how to link the fileds to the fileds within the database so that when I click submit it updates the table.
I'm new here and really, new to asp.net except the very basic things.
I am trying to create a very simple (I think simple) web form with five textboxes and three dropdown boxes and one submit button. The user enters information in the textbox fields and selects from the dropdown lists (which are populated from the database), hits enter and the database runs the query and returns information on a separate page (or can it return to the same page via panels?) The original page returned to a separate page using server transfer.
I have this page already existing in asp but feel that it would be much better served in asp.net.
Can someone point me to a post where I would guess this has been answered many times?
How do I submit the new data to the database, update the records and return the query?
