<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
<RowDefinition Height="40"/>
<RowDefinition Height="40"/>
<RowDefinition Height="40"/>
<RowDefinition Height="40"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Content="Nesting Layout Demo"
FontSize="15" FontWeight="Bold"
Foreground="Blue"
Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="3"/>
<StackPanel Grid.Column="0" Grid.Row="1" Orientation="Horizontal">
<Label Content="Name" FontSize="15" FontWeight="Bold" />
<TextBox Name="txtName" Text="Barack Obama" VerticalAlignment="Center"></TextBox>
</StackPanel>
<StackPanel Grid.Column="0" Grid.Row="2" Orientation="Horizontal">
<Label Content="City" FontSize="15" FontWeight="Bold"/>
<TextBox Name="txtCity" Text="New York" VerticalAlignment="Center"></TextBox>
</StackPanel>
<StackPanel Grid.Column="0" Grid.Row="3" Orientation="Horizontal">
<Label Content="State" FontSize="15" FontWeight="Bold"/>

</StackPanel>
<StackPanel Grid.Column="0" Grid.Row="4" Orientation="Horizontal">
<Label Content="Country" FontSize="15" FontWeight="Bold"/>
