TextBlock Text property was bound to a source, can I format the text display?

Question

I have a TextBlock object with a bound Text property.

I cannot control the binding source, but I can change Binding and TextBlock.

I want to format some key word display style...

For example:

I want to formart word "key" to bold, and formart word "RED" to red color,

And source data is "Example keyword and RED word".

After formatting, the equivalent Xaml should be

Example <Bold>key</Bold>word and <Span Foreground="Red">RED</Span> word

Of course, if the source was changed, Text must also changing synchronously.

What should I do?

you should go with richtextbox. TextBlock not support text formating as you want. — maulik kansara, Jul 05 '18 at 06:55
If your source data like 'Example keyword and RED word' then how you will decide which text is red and which text is bold ? — Anant Dabhi, Jul 05 '18 at 06:57
@maulikkansara I can change `TextBlock`, but I can't replace it — Mr. Squirrel.Downy, Jul 05 '18 at 06:57
@AnantDabhi text "key" to bold and text "RED" to red, that's I want to know... — Mr. Squirrel.Downy, Jul 05 '18 at 07:00

You can use TextBlock.inlines like below-

<TextBlock.Inlines>
    <Run FontWeight="Bold" FontSize="14" Text="Key" />
    <Run Foreground="Red" Text="Red" />
</TextBlock.Inlines>

You can also use binding for Text property in inlines.

You can refer this example.

Oh, you said I should move the `Binding` for `Text` to `Inlines`? I'll try it – Mr. Squirrel.Downy Jul 05 '18 at 07:03
I meant if you have different properties in code then you can use binding in inlines otherwise you are good to go with hardcoded texts if 'Key', 'Red' are fixed to be styled. – Gaurav Jalan Jul 05 '18 at 07:34
I can't confirm what text will in the Source, so I can't hard code – Mr. Squirrel.Downy Jul 05 '18 at 08:01
