Relational Data In Datagrid?

Aug 5, 2005

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.

Insert Relational Data In Access Database Using ASP.NET?

Oct 12, 2011

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'.

Display Two Relational Tables In A DataGridView

Jan 1, 2011

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.
