Horizontal alignment of datagrid row header content

Question

I got a simple question for all you friendly XAML experts. I have a datagrid with some row headers, which default horizontal alignment is center. All i want is to change this alignment to left. I have tried with the following code, but that dosent seem to work. Is it because the content consists of a textblock? If so, how do i get to change its alignment? I have tried changing the background of the header and it seems to work just fine.

Style:

<Style x:Key="DataGridRowHeaderStyle" TargetType="sdk:DataGridRowHeader">        
   <Setter Property="HorizontalContentAlignment" Value="Left"/>
</Style> 

Control:

<sdk:DataGrid x:Name="CheeseWeightsColumnStatsDataGrid"                           
              ItemsSource="{Binding CheeseWeightColumnStats}" IsReadOnly="True"              
              AutoGenerateColumns="False"
              HeadersVisibility="Row" 
              LoadingRow="CheeseWeightsColumnStatsDataGrid_OnLoadingRow" 
              RowHeaderStyle="{StaticResource DataGridRowHeaderStyle}">
</sdk:DataGrid>

Answer 1

I would create a template for the row header and bind it to a property of the class that is displayed in the row:

  <sdk:DataGrid.RowHeaderTemplate>
    <DataTemplate>
      <TextBlock Text="{Binding HeaderText}" HorizontalAlignment="Left"/>
    </DataTemplate>
  </sdk:DataGrid.RowHeaderTemplate>
