Powershell GUI format text on TextBox and RichTextBox

I was preparing some auditing and reporting tools for some of newly received projects and wanted a way to formatting representation of data on my GUI form in nice way. To show this nice formatting you can use tags inside TextBlock and RichTextBox inside xaml code and binding can be used.These tags are as same as html tags. below examples are used on TextBlocks. For more on tagging you can check this link https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.documents.span, below are the few examples I used for formatting.

Sample text <Span FontWeight="Bold">bold</Span>, <Span FontStyle="Italic">italic</Span> and <Span TextDecorations="Underline">underlined</Span> words.
Text <Span Foreground="Blue">with blue </Span> <Span Foreground="Orange">and</Span> <Span Background="Magenta">Magenta highlight</Span> 

Microsoft Powershell wpf textbox richtext format text background foreground bold color underline italic text formatting run.png

Formatting text data on Richtextbox is very easy and formatting is done in same manner using tags on paragraphs in below format.

<Run FontFamily="Segoe UI" Text="This is "/>
<Run Foreground="#FFF00C0C" FontFamily="Segoe UI" Text="Line 1 "/>
<Run TextDecorations="Underline" FontStyle="Italic" FontFamily="Segoe UI" Text="Underline and Italic"/>

The earlier shown tags example was to update XAML code directly, but I was also looking to update text after data collection, and my report should be looking nicer, cleaner and professional while sharing. As below I have 2 screenshots of same report but check the difference right side of screen definitely looks cool and much good in readable format, for example I need to highlight if there is a unwanted settings it should be shown as Red. 

Microsoft powershell wpf gui graphical user interface, forms Text formating textbox richtextbox controls, bold italic, backgroundproperty foregroundproperty, underlined strike, font size

Here in this script I have created two functions, first is for TextBox and second is for RichTextBox. The gist is as below.

First function TextFormatting has below code and it is to format text on Textblock. More information on this object can be found here https://msdn.microsoft.com/en-us/library/system.windows.documents.run(v=vs.110).aspx.

$ObjRun = New-Object System.Windows.Documents.Run
$ObjRun.FontWeight = 'Bold'
$ObjRun.Text = 'Your text'

$TextBlock.Inlines.Add($ObjRun)

Next function Format-RichTextBox formats text on richtextbox, more Information can be found on this .net object as below urls.
https://msdn.microsoft.com/en-us/library/system.windows.documents.textrange(v=vs.110).aspx
https://msdn.microsoft.com/en-us/library/system.windows.documents.textrange.applypropertyvalue(v=vs.110).aspx

$RichTextRange = New-Object System.Windows.Documents.TextRange($RichTextBoxControl.Document.ContentEnd, $RichTextBoxControl.Document.ContentEnd) #($RichTextBoxControl.Document.ContentStart, $RichTextBoxControl.Document.ContentEnd)
$RichTextRange.Text = 'YourText'
$RichTextRange.ApplyPropertyValue([System.Windows.Documents.TextElement]::BackgroundProperty, 'DarkGreen')
