Question : Visual Studio SQL Best Practices

I am once again trying to learn Visual Studio and I am looking for sample code that will show me how to connect to a sql database, plus how to create a basic data entry form where there is header information on top and line detail in the body. Let's say I have a DSN called MyConnection, a database called MYDataBase, userid is MyUser and the password is password. In that database are two tables, one called Header and the other called Detail. Here are the fields:
Header.OrderNumber
Header.CustomerNumber
Header.CustomerName
Header.OrderDate
in the Detail table are:
Detail.OrderNumber
Detail.LineNumber
Detail.ItemNumber
Detail.ItemDescription

So what I am looking for is a sample VS 2008 project that would show me how to bring up the form, establish the connection, on the top of the screen display the order header information and in the body display the order detail information. This would be a multi-line display.

As I search for solutions I am finding conflicting methods. I am an old C programmer and now I am trying to use VS 2008 C#.
If anyone can provide a basic example for this project that would be sufficient to get me started. Once I see the concepts actually in code I can take it from there.

You must put the code behind this:
      DisplayOrderDataGrid.DataSource = myDataSet.Tables["Orders"].DefaultView;
//MUST after this line
         DisplayOrderDataGrid.Columns[0].HeaderText = "Your Text";
         DisplayOrderDataGrid.Columns[0].Width = 500;
