Formatting text in a TextBlock

Question

How do I achieve formatting of a text inside a TextBlock control in my WPF application   e g   I would like to have certain words in bold  others in italic  and some in different colors  like this example     The reason behind my question is this actual problem   lblcolorfrom Content    Colour From      colourChange ElementAt 3  Value ToUpper      I would like the second part of the string to be bold  and I know that I could use two controls  Labels  TextBlocks  etc   but I d rather not  due the vast amount of controls already in use

You need to use Inlines    lt TextBlock Inlines gt       lt Run FontWeight  Bold  FontSize  14  Text  This is WPF TextBlock Example      gt       lt Run FontStyle  Italic  Foreground  Red  Text  This is red text      gt   lt  TextBlock Inlines gt    With binding    lt TextBlock Inlines gt       lt Run FontWeight  Bold  FontSize  14  Text   Binding BoldText     gt       lt Run FontStyle  Italic  Foreground  Red  Text   Binding ItalicText     gt   lt  TextBlock Inlines gt    You can also bind the other properties    lt TextBlock Inlines gt       lt Run FontWeight   Binding Weight            FontSize   Binding Size            Text   Binding LineOne     gt       lt Run FontStyle   Binding Style            Foreground  Binding Colour            Text   Binding LineTwo     gt   lt  TextBlock Inlines gt    You can bind through converters if you have bold as a boolean  say

There are various Inline elements that can help you  for the simplest formatting options you can use Bold  Italic and Underline    lt TextBlock gt      Sample text with  lt Bold gt bold lt  Bold gt    lt Italic gt italic lt  Italic gt  and  lt Underline gt underlined lt  Underline gt  words   lt  TextBlock gt      I think it is worth noting  that those elements are in fact just shorthands for Span elements with various properties set  i e   for Bold  the FontWeight property is set to FontWeights Bold    This brings us to our next option  the aforementioned Span element   You can achieve the same effects with this element as above  but you are granted even more possibilities  you can set  among others  the Foreground or the Background properties    lt TextBlock gt      Sample text with  lt Span FontWeight  Bold  gt bold lt  Span gt    lt Span FontStyle  Italic  gt italic lt  Span gt  and  lt Span TextDecorations  Underline  gt underlined lt  Span gt  words   lt Span Foreground  Blue  gt Coloring lt  Span gt   lt Span Foreground  Red  gt is lt  Span gt   lt Span Background  Cyan  gt also lt  Span gt   lt Span Foreground  Silver  gt possible lt  Span gt    lt  TextBlock gt      The Span element may also contain other elements like this    lt TextBlock gt       lt Span FontStyle  Italic  gt Italic  lt Span Background  Yellow  gt text lt  Span gt  with some  lt Span Foreground  Blue  gt coloring lt  Span gt   lt  Span gt   lt  TextBlock gt      There is another element  which is quite similar to Span  it is called Run  The Run cannot contain other inline elements while the Span can  but you can easily bind a variable to the Run s Text property    lt TextBlock gt      Username   lt Run FontWeight  Bold  Text   Binding UserName    gt   lt  TextBlock gt      Also  you can do the whole formatting from code-behind if you prefer   TextBlock tb   new TextBlock    tb Inlines Add  Sample text with     tb Inlines Add new Run  bold     FontWeight   FontWeights Bold     tb Inlines Add        tb Inlines Add new Run  italic      FontStyle   FontStyles Italic     tb Inlines Add  and     tb Inlines Add new Run  underlined     TextDecorations   TextDecorations Underline     tb Inlines Add  words
