Pass data from a WPF window to main window

Hi,

I have a DataGrid in my MainWindow.xaml which has various columns. I have another windows 'AddFixtures.xaml' which has a load of text boxes in, I want the data from the text boxes in this window to go to rows in the datagrid in MainWindow.xaml.

What I have tried:

I have a class for Fixture in the code behind 'AddFixture.xaml:

public class Fixture
        {
            public int fixtureID { get; set; }
            public int channelID { get; set; }
            public string fixtureName { get; set; }
            public string position { get; set; }
            public string patch { get; set; }
            public string mode { get; set; }
            public string power { get; set; }
            public string direction { get; set; }
        }

which then I get all the data from the various text boxes when I click the 'Ok' button:

private void BtnAddFixture_Click(object sender, RoutedEventArgs e)
        {
            var data = new Fixture {
                fixtureID = Int32.Parse(txtFixtureID.Text),
                channelID = Int32.Parse(txtChannel.Text),
                fixtureName = cbxFixture.Text,
                position = cbxPosition.Text,
                patch = cbxUniverse.Text + "." + txtChannel.Text,
                mode = cbxMode.Text,
                power = cbxSocca.Text + "." + cbxWay.Text,
                direction = "Forwards"
            };

        }

So I literally just need to get the var 'data' to my 'MainWindow' to add the rows.

I have binded the class to my datagrid columns like this:

<DataGrid x:Name="FixtureView"  AutoGenerateColumns="True" Grid.Column="1">
                <DataGrid.Columns>
                    <DataGridTextColumn Binding="{Binding fixtureID}" Header="Fixture ID" Width="*"/>
                    <DataGridTextColumn Binding="{Binding channelID}" Header="Channel ID" Width="*"/>
                    <DataGridTextColumn Binding="{Binding fixtureName}" Header="Name" Width="3.5*"/>
                    <DataGridTextColumn Binding="{Binding position}" Header="Position" Width="2*"/>
                    <DataGridTextColumn Binding="{Binding patch}" Header="Patch" Width="*"/>
                    <DataGridTextColumn Binding="{Binding mode}" Header="Mode" Width="1.5*"/>
                    <DataGridTextColumn Binding="{Binding power}" Header="Power" Width="*"/>
                    <DataGridTextColumn Binding="{Binding direction}" Header="Orientation" Width="2*"/>
                </DataGrid.Columns>
            </DataGrid>

Would be very greatfull if anyone could tell me what I need to do, have been searching for hours!
