Specify FontWeight for buttons

[Jeremy]

Hello,

I'm using the MessageBox control and I need to display a list of choices to my users. In my case, I need each button to be a simple text. In order to do that, I've come up with the following XAML:

<ControlTemplate x:Key="shareMessageBoxTemplate"
                 TargetType="telerik:RadMessageBoxControl">
        <Border
                Padding="12"
                Background="{StaticResource PhoneChromeBrush}">
            <Border.Resources>
                <Style TargetType="Button">
                    <Style.Setters>
                        <Setter Property="Template">
                            <Setter.Value>
                                <ControlTemplate TargetType="Button">
                                    <TextBlock
                                        Margin="14"
                                        Text="{TemplateBinding Content}"
                                        FontSize="30"
                                        FontWeight="ExtraLight"/>
                                </ControlTemplate>
                            </Setter.Value>
                        </Setter>
                    </Style.Setters>
                </Style>
            </Border.Resources>

            <Grid>
                <ContentControl x:Name="PART_Title" Visibility="Collapsed"/>
                <ContentControl x:Name="PART_Message" Visibility="Collapsed"/>
                <CheckBox x:Name="PART_CheckBox" Visibility="Collapsed"/>

                <ContentControl
                        x:Name="PART_ButtonsContainer"
                        HorizontalContentAlignment="Stretch">
                    <ContentControl.ContentTemplate>
                        <DataTemplate>
                            <StackPanel x:Name="PART_ButtonsPanel"/>
                        </DataTemplate>
                    </ContentControl.ContentTemplate>
                </ContentControl>
            </Grid>
        </Border>

The problem is that the 

FontWeight="ExtraLight"

option does not seems to be taken into account (the text is still rendered using a bold style).

Am I missing something ? I've also tried to set the resources in the Resources section of the ContentControl but it doesn't work either.

Regards,
Jeremy

Hello Jeremy,

 Thank you for writing.
I am afraid that I have no idea why your XAML does not work. It looks like it should. I tried setting ExtraLight as font weight for a standalone TextBlock on an empty page and it does not have any effect. Perhaps the ExtraLight value is broken in the WindowsPhone Silverlight. There seems to be no difference between ExtraLight and Normal.

Please write again if you need assistance with our controls.

Ok I found the issue (based on this thread):Font selection is a bit of a mess. You can select FontWeight for some typefaces such as Verdana, but for Segoe WP they created a separate FontFamily for each weight. Instead of FontWeight you would select FontFamily="Segoe WP Light"

In my case, changing the FontWeight="ExtraLight" to FontFamily="Segoe WP Light" did the trick.

Hey, Jeremy, thanks for info! That one is still actual, at least for wp7.
