Datagrid binding in WPF

I know this has been asked already but I have done almost everything what is suggested by developers.

<DataGrid x:Name="Imported" VerticalAlignment="Top"
          DataContext="{Binding Source=list}"
          AutoGenerateColumns="False" CanUserResizeColumns="True">
    <DataGrid.Columns>                
        <DataGridTextColumn Header="ID" Binding="{Binding Path=ID}"/>
        <DataGridTextColumn Header="Date" Binding="{Binding Path=Date}"/>
    </DataGrid.Columns>
</DataGrid>

I am trying to show this in modal dialog box and populating the license list in the constructor of the modal dialog box. But still nothing is getting populated inside the DataGrid.

Constructor code:

public diagboxclass()
{
    List<object> list = new List<object>();
    list = GetObjectList();
}
public class object
{
    string id;
    DateTime date;
    public string ID
    {
        get { return id; }
        set { id = value; }
    }
    public DateTime Date
    {
        get { return date; }
        set { date = value; }
    }
}

Do you guys think something to do with the object list?

Without seeing said object list, I believe you should be binding to the DataGrid's ItemsSource property, not its DataContext.

<DataGrid x:Name="Imported" VerticalAlignment="Top"
          ItemsSource="{Binding Source=list}"
          AutoGenerateColumns="False" CanUserResizeColumns="True">
    <DataGrid.Columns>                
        <DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
        <DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
   </DataGrid.Columns>
</DataGrid>

(This assumes that the element [UserControl, etc.] that contains the DataGrid has its DataContext bound to an object that contains the list collection. The DataGrid is derived from ItemsControl, which relies on its ItemsSource property to define the collection it binds its rows to. Hence, if list isn't a property of an object bound to your control's DataContext, you might need to set both DataContext={Binding list} and ItemsSource={Binding list} on the DataGrid).
