Answer 1

Name your DataGrid so that the code in the code behind can access it. In the textbox subscribe to the KeyUp or LostFocus events and find the object which matches what was put in the textbox.

Example List Contains Orders with a unique OrderId

Xaml

<DataGrid AutoGenerateColumns="True"
          Name="myGrid"
          ItemsSource="{Binding Orders}"/>

<TextBox x:Name="tbSelection"
         KeyUp="tbSelection_LostFocus"/>

Codebehind

private void tbSelection_LostFocus(object sender, RoutedEventArgs e)
{

    if (string.IsNullOrWhiteSpace(tbSelection.Text) == false)
    {
        int userOrderId; 

        if (int.TryParse(tbSelection.Text, out userOrderId))
        {
            var orders = myGrid.ItemsSource as List<Order>;

            var order = orders.FirstOrDefault(ord => ord.OrderId == userOrderId);

            if (order != null)
                myGrid.SelectedItem = order;
            else
                myGrid.SelectedIndex = -1; // Default to nothing.

        }
        else
            myGrid.SelectedIndex = -1; // Default to nothing.
    }

}

Result
