Здравейте! Проекта е на C# WPF базата с данни е MS - SQL Server 2014. Кода на Datagrid в XAML e:

 <DataGrid.Columns>
                <DataGridTextColumn Header="ID" Width="20"  Binding="{Binding Path = IDperson}"></DataGridTextColumn>

                <DataGridTextColumn Header="Name" Width="100" Binding="{Binding Path =Name}"></DataGridTextColumn>
                <DataGridTextColumn Header="Surname" Width="100" Binding="{Binding Path =LastName}"></DataGridTextColumn>
                <DataGridTextColumn Header="Phone Number" Width="150" Binding="{Binding Path =Phone}"></DataGridTextColumn>
                <DataGridTextColumn Header="Email" Width="200" Binding="{Binding Path =Email}"></DataGridTextColumn>
            </DataGrid.Columns>

Изполвам LINQ to SQL а ето и кода на C#

private void DataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            DataClasses1DataContext prova = new DataClasses1DataContext();
            List <Person1> dati = (from Person1 in prova.Person1s select Person1). ToList();
            ContactsGrid.ItemsSource = dati;

Не ми отчита грешки, но в крайна сметка ми излиза празен Datagrid.
