Textblock and HyperlinkButton do not align correctly - silverlight-4.0

Question

I'd like to have a hyperlink and a textblocks on the same line, however both controls act somewhat different. The hyperlink is just a few pixels more to the right, like there is a margin but it's not, is it? Just look at this piece of code:
<UserControl x:Class="SilverlightApplication7.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<TextBlock Grid.Row="2" Text="Umsatzsteuerart: " />
<TextBlock Grid.Row="2" Grid.Column="1" Text="Test" />
<TextBlock Grid.Row="3" Grid.Column="0" Text="Hersteller:" />
<HyperlinkButton Grid.Row="3" Grid.Column="1" Content="Test" />
<TextBlock Grid.Row="4" Grid.Column="0" Text="Umsatzsteuerart:" />
<TextBlock Grid.Row="4" Grid.Column="1" Text="Test" />
</Grid>
</UserControl>
Shouldn't all three ui-controls be aligned to the same line? Is there a solution for this problem? HorizontalAlignment doesn't effect anything...

Answer 1

Found the solution myself:
Setting the padding of the HyperlinkButton will align the hyperlink correctly.
