I think it's kind of noob question but I'm new to SQL Server in .NET and I've already lost several hours on this...
I started new project, inserted DataGridView on empty form and as Data Source I chose Add->Database and I created new SQL Server Database File. I called it db.mdf. Now I get DataSet named dbDataset and BindingSource named dbDataSetBindingSource. I also added LINQ to SQL Classes to my project and dragged my table (where I added some rows before) to my .dbml. Next I doubleclicked my dbDataset and in designer dragged and dropped the same table.
I hope you have an image now ;). The thing is that when I run program, nothing shows in DataGridView. I know that I can do
dbDataClassesDataContext db = new dbDataClassesDataContext();
var records= from rec in db.MyTable select rec;
dataGridView1.DataSource = records;
And it works perfect. But I believe that dbDataSet and dbDataSetBindingSource should work too... How to use them just to show data in DataGridView?
