            <Setter Property="Visibility" Value="Visible"/>
        </DataTrigger>

wish help you to fix your issue How can I different design the text within the TextBox-Element in XAML , You need to use the WPF RichTextBox control for that.
Example:

code :

<RichTextBox x:Name="txtRichBox">
                        <FlowDocument>
                            <Paragraph>
                                I am bold inside
                                <Bold>not outside</Bold>
                            </Paragraph>
                        </FlowDocument>
</RichTextBox>

Boolean to Visibility Converter in Win RT XAML not working first time

like below fixes the issue Nevermind... It was my own stupid fault, it seems I had another condition in the getter of the IsValid property which was always false when it shouldn't have been.
Fixed :)

will be helpful for those in need If you are only having one player on each client you could set the user class to a static class and then call that from each page.
e.g

code :

public static class Player
{
   public static string nickname{get; set;}
   //ect
}

Player.nickname = "myname";

Updating XAML component Visibility in real time - UWP

By : Hannes van Zyl

hop of those help? To clarify, data bindings in WPF are not continuously re-evaluated. Once the UI gets a value for your JobStatus property, it's not going to ask again. Unless, that is, you tell it to.
The more common way to do this is to implement INotifyPropertyChanged on your ViewModel and then fire the PropertyChanged event. But you can also force the binding to update programmatically by calling the UpdateTarget method of the binding expression:

code :

sample.GetBindingExpression(TextBlock.VisibilityProperty).UpdateTarget();

var timer = new System.Windows.Threading.DispatcherTimer();
timer.Interval = TimeSpan.FromSeconds(1.0);
timer.Tick += timer_Tick;
timer.Start();
...
void timer_Tick(object sender, EventArgs e)
{
    sample.GetBindingExpression(TextBlock.VisibilityProperty).UpdateTarget();
}
