Does anyone have an example using codebehind (in vb) where records are
pulled out of a table on the .vb page and used to populate the form on
the .aspx page?
All I see are examples where form data from .aspx page is submitted from
the .vb page to a table.
Can everything in asp.net be done using codebehind? Or is it limited?
I dont know what you want to do using code behind .Though you can certainly
push your business logic in corresponding vb or cs file.
I been doing component coding in C# and aspx is just reflecting what is in
cs file.
This example may help out ..else pleasr rephrase what you want to get
through code behind feature.

Description :
I am using Serviced components so you might not need to understand it fully.
Just see Public variables in CS file ..and method PopulateArray(). This
method queries an out sider component to get data .And then initialize
public data members , they are then used in 'aspx' file.
You can access every thing (public) in you code in your aspx page using same
<% %> directive.
Problem solved ????
Let me know if it persists. .
