Question

I have the following AppBar.

<Page.BottomAppBar>
    <AppBar x:Name="bottomAppBar" Padding="10,0,10,0">
        <Grid>
            <StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
                <Button x:Name="switchMeasurementMode" AutomationProperties.Name = "Breath rate" Style="{StaticResource AppBarButtonStyle}" Click="switchMeasurementMode_Click" />
            </StackPanel>
        </Grid>
    </AppBar>
</Page.BottomAppBar>

It looks like this

I tend to change its text during run-time with the following C# code

    private void switchMeasurementMode_Click(object sender, RoutedEventArgs e)
    {
        this.switchMeasurementMode.Name = "111";
    }

But the button text is not changed. Is there anything I had missed out?

If you use the default styles for AppBar in Windows 8 C# projects, then you have to change the attached property AutomationProperties.Name either in XAML using:

AutomationProperties.Name = “new name”

or in code using:

Button.SetValue(AutomationProperties.NameProperty, “new value”);
or
AutomationProperties.SetName(Button, “new value”);
