WPF Best Practice for DataEntry Window

i`m currently playing around with WPF and now i wonder what would be the layout for a typical dataentry window (20+ textboxes and stuff).

atm i`m using a grid object like this (basic sample)

    <Grid Margin="2,2,2,2">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"></ColumnDefinition>
            <ColumnDefinition Width="*"></ColumnDefinition>
        </Grid.ColumnDefinitions>

        <Grid.RowDefinitions >
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
        </Grid.RowDefinitions>

            <Label Grid.Row="0" Grid.Column="0">Vorname:</Label>
            <TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Path=Surname, UpdateSourceTrigger=PropertyChanged}" ></TextBox>

            <Label Grid.Row="1" Grid.Column="0">Nachname:</Label>
            <TextBox Grid.Row="1" Grid.Column="1" Text="{Binding Path=ChristianName, UpdateSourceTrigger=PropertyChanged}"></TextBox>

            <Label Grid.Row="2" Grid.Column="0">Strasse (Wohnsitz):</Label>
            <TextBox Grid.Row="2" Grid.Column="1" Text="{Binding Path=Street1, UpdateSourceTrigger=PropertyChanged}"></TextBox>

            <Label Grid.Row="3" Grid.Column="0">Ort (Wohnsitz):</Label>
            <TextBox Grid.Row="3" Grid.Column="1" Text="{Binding Path=Town1, UpdateSourceTrigger=PropertyChanged}"></Tex
