    <p>Try using a BindingList&lt;> instead of List&lt;> and (as already suggested by Daniel), implement INotifyPropertyChanged. However, I think you can also call .Refesh() if you didn't want to implement the INotifyPropertyChanged interface.</p> <p>Here's an example ripped from <a href="http://www.switchonthecode.com/tutorials/csharp-tutorial-binding-a-datagridview-to-a-collection" rel="noreferrer">here</a></p> <pre><code>public class Car : INotifyPropertyChanged { private string _make; private string _model; private int _year; public event PropertyChangedEventHandler PropertyChanged; public Car(string make, string model, int year) { _make = make; _model = model; _year = year; } public string Make { get { return _make; } set { _make = value; this.NotifyPropertyChanged("Make"); } } public string Model { get { return _model; } set { _model = value; this.NotifyPropertyChanged("Model"); } } public int Year { get { return _year; } set { _year = value; this.NotifyPropertyChanged("Year"); } } private void NotifyPropertyChanged(string name) { if(PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(name)); } } _dgCars.AutoGenerateColumns = false; DataGridViewTextBoxColumn makeColumn = new DataGridViewTextBoxColumn(); makeColumn.DataPropertyName = "Make"; makeColumn.HeaderText = "The Car's Make"; DataGridViewTextBoxColumn modelColumn = new DataGridViewTextBoxColumn(); modelColumn.DataPropertyName = "Model"; modelColumn.HeaderText = "The Car's Model"; DataGridViewTextBoxColumn yearColumn = new DataGridViewTextBoxColumn(); yearColumn.DataPropertyName = "Year"; yearColumn.HeaderText = "The Car's Year"; _dgCars.Columns.Add(makeColumn); _dgCars.Columns.Add(modelColumn); _dgCars.Columns.Add(yearColumn); BindingList&lt;Car&gt; cars = new BindingList&lt;Car&gt;(); cars.Add(new Car("Ford", "Mustang", 1967)); cars.Add(new Car("Shelby AC", "Cobra", 1965)); cars.Add(new Car("Chevrolet", "Corvette Sting Ray", 1965)); _dgCars.DataSource = cars; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
