Letterspacing (tracking) with TextBlock in WPF?

What is the best way t开发者_开发问答o do letterspacing (tracking) with TextBlock in WPF?

I would think TextBlock.Typography would have taken care of this but it doesn't. What is the best approach?

It seems that this problem cannot be solved easily. You can google and find something like this http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/789c3e1b-e3ae-476f-b37f-d93ef6d0cb7b/ (approach with glyphs). But taking into account the fact that String is enumerable collection sometimes you can solve your problem with markup like this:

<Grid>
    <ItemsControl>
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid Rows="1"/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemsSource>
            <System:String>
                Hello World
            </System:String>
        </ItemsControl.ItemsSource>
    </ItemsControl>         
</Grid>

Tuning this markup (panels, templates) you can get any desired layout of string. And of course you could separate this markup to a special UserControl. Just as a variant for particular cases.

I used the approach suggested by Kreol, and found this to be working except that some letters are wider than others.

When using a UniformGrid every column have same width by definition. This lead to variable spacing between letters.

Instead I used a stackpanel with horizontal orientation, and a left margin on each element:

<Grid>
    <ItemsControl ItemsSource="{Binding SomeString}" HorizontalAlignment="Center" VerticalAlignment="Center">
            <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                            <StackPanel Orientation="Horizontal" />
                        </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
                <ItemsControl.ItemContainerStyle>
                        <Style>
                            <Setter Property="Control.Margin" Value="1,0,0,0"/>
                            <Setter Property="Control.Foreground" Value="#1E395B"/>
                         </Style>
                </ItemsControl.ItemContainerStyle>
        </ItemsControl>
</Grid>
