How can I align a CheckBox with its content?

I know it's too late, but here is a better solution, without setting margins. Margins should be set differently for different heights of TextBlock or Checkbox.

<CheckBox VerticalAlignment="Center" VerticalContentAlignment="Center">    <TextBlock Text="Well aligned Checkbox" VerticalAlignment="Center" /></CheckBox>

Update:

It's worth checking out @nmarler's comment below.

Edit - New Answer: (previous was no good)

Not the best way i believe , but can do the work:

<CheckBox>    <TextBlock Text="Poorly aligned CheckBox" Margin="0,-2,0,0"/></CheckBox>

Using negative margin to push the content up, result:

The default Style of a CheckBox don't look like that in WPF. It aligns perfectly in both XP and Windows 7. Can you give a better description of how to reproduce this problem?

Two things I can think of to get the offset that you're seeing is either changing the Padding or the VerticalContentAlignment. The default CheckBox value for VerticalContentAlignment is Top and a CheckBox with Content has Padding set to "4,0,0,0". Try to change these two around and see if it makes any difference.

Here is a comparison

From the following Xaml

<Grid>    <Grid.RowDefinitions>        <RowDefinition Height="*"/>        <RowDefinition Height="*"/>        <RowDefinition Height="*"/>        <RowDefinition Height="*"/>    </Grid.RowDefinitions>    <CheckBox Grid.Row="0"              Content="Poorly aligned CheckBox" Margin="9" />    <CheckBox Grid.Row="1"              Content="Padding=4,4,0,0" Margin="9" Padding="4,4,0,0"/>    <CheckBox Grid.Row="2"              Content="Vertical Center" Margin="9"              VerticalContentAlignment="Center"/>    <CheckBox Grid.Row="3"              Content="Vertical Top" Margin="9"              VerticalContentAlignment="Top"/></Grid>
