Button.Content changes in RC0/RTW?

Question

I noticed after upgrading to RC0 or RTW that my custom Button.Content is now centered and will not stretch to the entire width of the Button.

Is there a breaking change I missed?

Well, it seems as though the default value for HorizontalContentAlignment must've changed.  I fixed my issue by explicitly setting it to Stretch.

Hi all,

This property only affects a control whose template uses the HorizontalContentAlignment property as a parameter. On other controls, this property has no impact. The default is HorizontalAlignment.Center. Therefore, we need to set it implicitly.  For example,

        <Button Width="150" Height="30" HorizontalContentAlignment="Stretch" >
            <Button.ContentTemplate>
                <DataTemplate>
                    <TextBox Text="50"></TextBox>
                </DataTemplate>
            </Button.ContentTemplate>
        </Button>

Best regards,
