Vista - How do I get to a TextBlock inside a Style

I have defined the following style:

<Style x:Key="EmployeeRequestCustomHeaderLabelArea" TargetType="{x:Type
igDP:HeaderLabelArea}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type igDP:HeaderLabelArea}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock TextAlignment="Center" Grid.Row="0" FontSize="16"
FontStyle="Oblique" Foreground="White" Text="Are Awaiting Your
Approval"></TextBlock>
<ContentPresenter Grid.Row="1" Content="{TemplateBinding
Content}"/>
</Grid>
</ControlTemplate>

</Setter.Value>
</Setter>
</Style>

The style is used here:

<igDP:XamDataPresenter x:Name="EmployeeRequestDataPresenter">
<igDP:XamDataPresenter.FieldLayoutSettings>

<igDP:FieldLayoutSettings
HeaderrLabelAreaStyle="{StaticResource

EmployeeRequestCustomHeaderLabelArea}"/>
</igDP:XamDataPresenter.FieldLayoutSettings>


How can I programmatically change the Text property in the TextBlock?

I'd say the easiest way is to set a Name on the TextBlock. Then you can use:

TextBlock myText
= bn.Template.FindName( "myTextBlock", bn ) as TextBlock;
if ( myText != null )
{
myText.Text = "World";
}

Note: The VisualTree is not expanded yet in the Window's constructor, so
you have to wait until the Loaded event is fired to access the
Template's elements.

HTH,
