I've read a few threads here but can't seem to get a grip on this. I want to get Vendor data from an access table. And in a datagrid, I want to have a plus sign next to each vendor and when expanded, show the employees of that particular vendor.

I have two relational tables: the Profiles table which contains 3 kinds of user roles (Manager, Developer, Common User) and the Users table which contains information about the user and their roles ID (Profile_ID field) in the Access 2010 database.
I created a Webform in ASP.NET which should simply register users, asking for their names, selecting their roles in a dropdown list and inserting it all in the Access database. As in the following code:
Dim cs As String = ConfigurationManager.ConnectionStrings("Access 2010").ConnectionString
Dim cn As New OleDbConnection(cs)
[Code].....
It happens that I can't insert in the database because they have a relationship between each other, it gives me an error. Actually, I just need to insert data in the Users table 'cause the roles are fixed. How can I do it?
EDIT
The error I get is You can not add or change records, it is necessary that they have a related record in table 'Profiles'.

I have two tables: One wich contains the columns "first_name", "last_name" and "status_id". The other table contains "status_id" and "description".
Now, I want to display "first_name", "last_name" and "description" in one DataGridView. What is the best way to do this?
What I'm doing now, is that I'm manually adding a datacolumn to the first table. Then I'm looping through each row and filling the new column manually. Now, that doesn't seem very smart and efficient, but I haven't found any better solution.

I have a form with datagridview. I populate my datagrid with my dataset data.
Everything is going fine.
The only issue i found is.
if i lock the system and leave the form with datagridview containing data it it, and after some time (say 10 mins, when monitors goes to standby mode) if i unlock the system i see that the datagrid is empty. but a window with label has no effect its intact.
It appears my connection to the db is correct when I select different options the datagrid displays the correct number of records. So I am not sure why I can not see the data in the grid.[code]....
