RichTextBlockOverflow content - xaml

How can I get content from RichTextBlockOverflow (for example some text)?
And maybe someone know can I set RichTextBlockOverflow invisible?

RichTextBlockOverflow doesn't have its own content, it shows overflow content from the RichTextBlock it is linked to. If you want to know what text shows in the RichTextBlockOverflow you can use ContentStart ContentEnd properties and extract text from the RichTextBlock using Select and SelectedText

How can I make an image float or right-align in a Google Colab markdown cell?

To explain the process that is going on in my notebook code, I use markdown text boxes between snippets of code. I would like to use small images to illustrate the text (a diagram often makes text clearer).
I cannot find a way of having those images floating on the right however.
I tried adding tags with CSS styling, but Colab seems to be removing those. I tried wrapping things in , but again no luck there.
You can also use the now deprecated align attribute on the image tag.

One option is to use an HTML cell with the code hidden, which is triggered by the presence of a form title. For example, create a code cell with this content:
##title Some Stuff
%%html
Here are some words.
<img src="https://www.w3schools.com/html/smiley.gif"
style="float:right;width:50px;height:50px;">
Here are some other words and there is an image floating around it.
Then execute the cell & double click on the rendered title to hide the source. The result looks like this:

Applying Style To RichTextBlock using Range Information in UWP

This code snippet comes from RichEditBox style application,
Document.Selection.SetRange(paragraphStartIndex, paragraphStartIndex + data.Text.Length);
Document.Selection.CharacterFormat.Strikethrough = FormatEffect.On;
However, can we do similar things with a RichTextBlock?
I know that I can add a <run> or a <Span> and add style information to these elements, but is there any way to grab the whole RichTextBlock content and apply style to a range of text within it?
RichTextBlock and RichEditBox are rich text-related controls, but they are very different in display.
The process of RichEditBox displaying rich text is like drawing on paper, because it carries the modified function, so there is a complete Document as a carrier.
RichTextBlock is not responsible for modification, it is only responsible for display, so it is more like building blocks. RichTextBlock has a lot of display elements to render different visual effects, but they are independent of each other. You can't set effects for a certain character. You can only set the effect for the entire block (such as Paragraph).
When you select text in the RichTextBlock, you can get the parent element of the currently selected text point through RichTextBlock.SelectionStart.Parent or RichTextBlock.SelectionEnd.Parent, and set the effect.
Best regards.

Can not display tooltip when mouse is over text on PDF

I need some way to have like a tooltip when the mouse is over text. I mean, something like <block>Some text</block> and when the mouse is over "Some text" y need to display a tooltip, just like an HTML link that when the mouse is over it, a tooltip with the value of the title attribute is displayed.
I've searched so much and could not find the answer to my problem.
Annotations in PDF are not part of the XSL FO Specification. The only product I am aware of that supports such things is RenderX's XEP engine. You can review the documentation on this feature here:
http://www.renderx.com/reference.html#PDF%20Note%20Annotations
One would use:
<fo:block>Note here<rx:pdf-comment content="This is the text of a popup comment"/> and some text after</fo:block>
rx:pdf-comment has additional attributes to set the title of the annotation, the color of the annotation and the opacity it displays with. You can also change the icon used in the PDF.

Silverlight 4 RichtTextBox - how do I get the text without the formatting?

How do I get the text out of a Silverlight 4 RichTextBox without the formatting? I know the Xaml property will give me the XAML but I just want the text.
This is a little late, but I will post anyway. There is a trick that involves selecting all the text in code and then accessing the Text propety of the TextSelection object. Like so:
myRichTextBox.SelectAll();
var plainText = myRichTextBox.Selection.Text;
I am using it in my apps and although it is not the prettiest solution, it works. Found it here:
http://forums.silverlight.net/forums/p/184560/422007.aspx
If you just want text, why not use TextBox instead?
There are various third-party components that support this kind of functionality (unfortunately paid). For example, Telerik's RadRichTextBox supports both highlighting and exporting rich text content as plain text, latter trough component called TxtFormatProvider.

how to show rich formatted text in textarea

I have a form that uses Richtexteditor of Flex3 to write in their reply. The reply is then posted to a textarea, where all of the formatting is lost! I have embedded the font since I was doing some tweeening on the text boxes.
I need to find out how keep the formatting intact in the textarea from richtexteditor!
has anybody an idea?
Make sure that you set the htmlText property on the TextArea, not just text.
