How can I define DataGrid's rows declaratively in XAML?

Question

I have this code and I need to bind second and third cells in rows to different properties. Sorry for my bad english.

<DataGrid AutoGenerateColumns="False" HorizontalAlignment="Stretch" Name="measureDataGrid" VerticalAlignment="Stretch">
                                        <DataGrid.Columns>
                                            <DataGridTextColumn x:Name="measureName" Header="Наименование" Width="*" />
                                            <DataGridTextColumn x:Name="measureValue" Header="Значение" Width="Auto" />
                                            <DataGridTextColumn x:Name="measureDestValue" Header="Потенциальное значение" Width="Auto" />
                                        </DataGrid.Columns>
                                        <DataGrid.Items>
                                            <!--<DataGridRow>-->
                                            <RowDefinition/>
                                            <RowDefinition/>
                                            <RowDefinition/>                                                           
                                        </DataGrid.Items>                                   
                                    </DataGrid>
